Qmidiroute patched for some GS use

I bought a D-05 and wanted to experiment with it by playing my usual midi playlist. Sadly, I didn't know of a way to automatically forward certain program numbers to it. For instance, I wanted to send all piano (PC#1-6) to it, while using the SC-8850 for the rest. Qmidiroute can be used, but based on the channel, not the program number, and that would mean creating a new configuration for every midi file that changes where the pianos are. Anyway, since a solution wasn't immediately apparent, I decided to build this functionality into qmidiroute with another patch. It's finally done!

As far as features go, it now has this "Program Forward" map, where an input value (PC#, 0-127) may be matched to output to, in addition to the alsa port mapped to whatever device, a specific (or offset) channel, a specific value PC# (or range), and a fixed specific GS Variation (0-65) (or -1 can be used to just pass the input variations).

I also added a "SysEx Forward" map so that the SC-8820 can be on equal footing when used with the SC-8850. It takes no input arguments, and just outputs to the specified port.

SysEx Forward is also useful when used additionally with the "Drum Forward" map. Drum Forward takes an input channel range and matches, like Program Forward, with the PC#. For simplicity it just outputs to the same channel as was input. SysEx Forward is needed because GS SysEx can be used to alter any channel into becoming drums. Without SysEx Forward, drums may be forwarded to a channel other than 10 and would play as piano or whatever instrument happened to be there. Anyway, Drum Forward's output value (PC#) range can be set (0-127) to select the wanted Drums. Of course, the alsa port is set to specify the output device.

Qmidiroute has 2 virtual output ports by default, but if you need more, the amount can be given on the command line with -p, like so:
qmidiroute -p3

There you have it! The uses are many, but I've considered testing certain SC-8820 instruments along with the rest on the SC-8850. So far, I've just been playing with the D-05 and SC-8850, though. It's a neat perk to be able to "Program Forward" SC-8850 default instruments into more favorable variations, such as "Wide FreHrns", without having make modifications to every MIDI file. I'll include a test qmidiroute mapping that plays with that idea a bit, sending pianos 1-6 (0-5) to SC-8850 Part A as "St.Soft EP", and to Part B as "EP Legend", while French Horns are all changed to "Wide FreHrns" and play on both Part A and Part B. To set this up, I use aconnect to connect the SC-8850 parts to the virtual ports, in a terminal, like so ("aconnect -l" will list all ports available):
aconnect 129:1 32:0 ; aconnect 129:2 32:1
Also, you need to be sure your player is connected to qmidiroute's input (which in my example is 129:0), and that, likely, is done through the GUI of the player, but otherwise could be done with aconnect similarly to the above commands (where 14:0 is the player's output port):
aconnect 14:0 129:0

Again, I based this patch on the standard debian qmidiroute 0.4.0 source, but have also included one that will incrementally patch on top of my previous Note Off patch. Both retain the Note Off map functionality too, to fix the CM-32L/CM-64 overflow assign.

I hope it's useful to someone other than me. Enjoy:

Edit 2019-11-13 Found 2 bugs already, and fixed them. I'm sorry to those of you that already downloaded it, if you noticed what I just did: After my gs-reset.mid file, with the example .qmr file the non-variation SC-8850 Parts were being changed to variations 8, and 10). Also, the Drum Forward was stuttering because it was checking for changes in the variation. Drums not having a variation, it was never setting a value. What a silly mistake, but I guess that's what last minute changes lead to... more changes after tests are repeated.

Final Edit (I hope, for a long time) 2019-11-14 After the drums were working, I noticed and fixed a bug where the GS Map being set on drum channels would be retained when the user specifies one that exists in a more recent map, so just like with standard GS instruments, I decided to let the user choose which map (through their module's front panel buttons) by first sending the drum map bank as "0" (and rewriting all possibly conflicting changes) when the GUI-set output PC# ("Value") maps to any PC# higher than zero.

Edit 2020-03-31 Everything else still seems to be working and now I've patched a segmentation fault that happened when time-shifting audacious. It probably occurred under other conditions too, but for me, audacious made it obvious. Now, I can once again enjoy the very useful feature of audacious to be able to skip to anywhere in a track without playing the whole song (although, skipping SysEx should be avoided). If I'm not mistaken, this bug has existed for a very long time, and is in the original, unpatched, version of qmidiroute-0.4.0 and probably well before that.

Thanks if you're trying it out,

Because my edit yesterday didn't trigger an updated date, I'm posting here for anyone else who has experienced the qmidiroute crashes I have. I think that latest patch solves them. It's much more stable for me anyway.

I hope it helps,

At long last, I've upgraded everything I can think of, and they seem to be working well!
This changed enough, that I thought a version bump of .1 was justified, so this patch upgrades debian's qmidiroute-0.4.0 source (or any of my previous patched versions) to 0.5.0.
(106.69 KiB) Downloaded 214 times
I added Channel & Polyphonic Aftertouch matching. It's a neat thing to play with: Polyphonic Aftertouch to Note On creates a fun effect, at least with instruments that naturally decay. :) Of course, you can, instead, use these to change any controller numbers into aftertouch, although most synths probably can trigger effects more easily from controller numbers than aftertouch of either type. You can also match "Note On" input to "Polyphonic Aftertouch" output to re-record aftertouch information with a velocity-only keyboard (but when doing this you may want to only match input velocities greater than zero, since my keyboard sends "Note Off" as "Note On" with a velocity of 0, and the aftertouch will turn off as soon as each key isn't held. On the other hand, if you do this, the aftertouch will never turn off, but if you play softly, it can be subtle).

The 65 variations I'd allowed sending to, previously, for the SC-8850 was too low to use many of the INTEGRA-7's banks, so I expanded them (as well as the banks) to the full MIDI range of 0-127. Along with those expansions, I also tried to align my design more with qmidiroute's, and so now Program & Drum Forwarding can match on input bank and variation, rather than just program number.

SysEx delays are now able to be set, differently (whether unmatched, forwarded, or edited).

SysEx Edit is my nicest addition, but its syntax is pretty particular. My example .qmr files should help anyone wanting to write their own. First, SysEx bytes (in hexadecimal characters without the leading "0x", i.e. just "f0" or "F0") are separated by spaces, while multiple messages are separated by commas ",".
A message may be matched from input to output as a list of constant bytes, or something more fancy may be done. If you want to change one message into more than one, you can include the message to be matched on input twice or more (each separated by a comma), and for each of those, put the desired message on output. The opposite works too. You can match multiple input messages and change each into the same output message. In the INTEGRA-7 qmr I'm including, I match both GS and GM1 resets to replace each with a GM2 reset. In input, I have "f0 41 10 42 12 40 00 7f 00 41 f7, f0 7e 7f 09 01 f7" (GS & GM1 reset), and in output there's "f0 7e 7f 09 03 f7, f0 7e 7f 09 03 f7" (GM2 reset for each input).
While that can be useful, better still is the ability to change a message with ranges. To get the MT-32's MASTER VOLUME to a nice level, I match 00-64 (0-100 in decimal) to 0-30 (0-48 in decimal), but since this changes the checksum, we also need some more special syntax. I got this idea from the Behringer BCR2000, but had to expand it for my use: "cks-1 05:08" specifies the type of checksum (1 being Roland, 2 or 3 for other types, as the BCR specifies - described on page 55 of "B-Control MIDI Implementation" by Mark van den Berg @, along with the address start byte offset as hexadecimal (byte number 0 in the message is F0), separated by a colon (:) from the data start byte offset as hexadecimal (directly after the address in this case, numbered again from 0 on byte F0). So for the complete example of MASTER VOLUME editing, I have "f0 41 10 16 12 10 00 16 00-64 cks-1 05:08 f7" as input and "f0 41 10 16 12 10 00 16 00-30 cks-1 05:08 f7" as output. The checksum will be written to the offset "cks-#" (the necessary "##:##" isn't counted in this offset) is from the end f7/F7 byte. This way, a longer message including the MASTER VOLUME byte somewhere in the middle, will still write the checksum to the byte just before the f7/F7. If one wanted to set a constant MASTER VOLUME, that could be done with "f0 41 10 16 12 10 00 16 00-64 cks-1 05:08 f7" as input , and "f0 41 10 16 12 10 00 16 30-30 cks-1 05:08 f7" as output. If the input edit includes a range (-), the output must too, even if the output range creates a constant value like that. Either of the checksum (cks-#) or range (-) bytes may be at different offsets (from input to output), although there's no utility I've seen for that behavior.

SysEx Edit also has a rarely needed feature of removing sequentially duplicate SysEx messages (I encountered it in some ZUN SC-8850 SMFs). It's best to not enable it, in most cases, though as playback containing only GS reset SysEx messages will only output the first GS reset.

In debugging some playback on the INTEGRA-7, I decided to add the option to delay between bank and variation messages (this setting is found on the unmatched tab, even though it affects all). Although I solved the INTEGRA-7 issue I'd been having another way (holding back these messages until the program change is received so it is known where to send them), I read in Yamaha's "XG Format Music Data Production Recommendations" ("sisin") manual that XG requires a delay between these CC0 and CC32 messages (of "1/480", however I haven't researched if that's in seconds or some other unit, it's on page "5", or 9, of the version 1.15 pdf).

Another change I almost forgot to mention is that the check boxes in the Event Log portion of the window is now saved, so you can disable the logging messages for a headless device and save CPU usage.

Finally, and this is a big internal change, but hopefully unnoticeable: While trying to debug some anomalies with SC-8850 variations being set, I decided to port the entire input procEvents() loop from Qt to pthreads, just in case Qt's event loop wasn't processing input fast enough and missing some messages. With this change, I also used aseqdump's idea to put ALSA in non-blocking mode, in hopes it will help. In the end, I'm not sure if Qt's event loop being slow was the issue, but it doesn't hurt, and I was already using pthreads for the SysEx delays code, having wanted to learn it for a while.

Sadly, the addition of these match types makes save files incompatible with prior qmr format, so it's a good idea to keep the version you have saved your previous .qmr files in, to manually migrate values (with each version's window open) and save new .qmr files. I updated the ones I'm including again, though, so no worries if you've just used them. It's actually not too hard to examine the saves as text files and edit them accordingly, but it's probably not for the uninitiated. By releasing all these changes at once, I hope to avoid future .qmr file incompatibilities.

Finally, with the input bank/variation matching, I've included a few different capital tone fallback qmr files. (One just performs SC-55 fallback, although it's really to give a closer SC-55 approximation on an SC-55mkII since the original SC-55 does its own fallback. One makes the SC-55mkII "fallback" (well, forward and back, in this case) to "Fl.Key Click" to emulate the oldest SC-55. And the final one just performs SC-55mkII fallback so it never sees a variation it doesn't recognize, as it would've done if Yamaha hadn't had capital tone fallback patented then.)

Edit 2020-11-11: I decided to fix a bug due to not realizing ALSA may split SysEx into 256 byte chunks, so although it hasn't been downloaded yet, it would be best to wait until I patch it. I'll let you know when done. Thanks for your patience. :) -Done! (Edit 2020-11-14) Split SysEx messages are recombined so that internal checksum calculation will always work. It can be used to standardize MIDI file recording with arecordmidi, which would have recorded them split: now you can connect qmidiroute between MIDI input ports and your recording program to recombine each SysEx message to its original entirety. I also took the opportunity to speed up the input function substantially so the chances of lost SysEx are minimal (even compared to aseqdump somehow!). Audacious-3.4.3 (the last version I can find with the necessary AMIDI-Plug ALSA Backend, for some reason) may skip fast SysEx on a file's first play, but replaying it (even right away, before it finishes) seems to send all SysEx messages. However, aplaymidi, itself, is reliable and always seems to send all SysEx.

I hope you are as excited as I am about this upgrade.

I had a fairly hard time installing this on another debian machine of mine today, so I feel obligated to tell anyone trying this for themselves the steps I took:

In a terminal, go to the directory the patches were downloaded to

Code: Select all

cd ~/Downloads/
Become root:

Code: Select all

& enter your root password

Code: Select all

sudo su
& enter your user account password

Extract the patches to /usr/src with something like this:

Code: Select all

7z x -o/usr/src ./qmidiroute-0.4.0-to-0.5.0-patches.7z
Go where we want to extract the source

Code: Select all

cd /usr/src/
Download & extract debian's source for qmidiroute-0.4.0

The patch version I uploaded today (0.5.1) adds and modifies about three main things:
(113.34 KiB) Downloaded 214 times
1. SysEx Edit: If you have multiple offset values that do (or could) occur on the same message, you can now group them with a new syntax to denote it. That is, wrap each comma-separated message in parentheses. Because just describing it can seem complicated, I'll give the example of my first reason for it. MT-32 family Part Volumes are set through a range of semi-close addresses, so in at least one occurrence, they might be just in a single, long, SysEx message like so (from KQ4.SYX):
f0 41 10 16 12 03 00 00 01 0c 18 32 0c 00 01 00 64 06 00 00 00 00 00 00 01 30 18 32 0c 00 01 00 00 07 00 00 00 00 00 00 01 14 18 32 0c 00 01 00 64 0a 00 00 00 00 00 00 01 1d 18 32 0c 00 01 00 60 09 00 00 00 00 00 00 00 3b 18 32 0c 00 01 00 64 07 00 00 00 00 00 00 00 20 18 32 0c 00 01 00 64 05 00 00 00 00 00 00 00 24 18 32 0c 00 01 00 64 0b 00 00 00 00 00 00 01 3a 18 32 0c 00 01 00 50 0e 00 00 00 00 00 00 31 f7

I include the old Master Volume translation first, but then (contained in parentheses) lower all the parts' volumes. Here's what goes in SysEx Edit Input:
f0 41 10 16 12 10 00 16 00-64 cks-1 05:08 f7, (f0 41 10 16 12 03 00 08 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 18 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 28 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 38 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 48 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 58 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 68 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 00 78 00-64 cks-1 05:08 f7, f0 41 10 16 12 03 01 08 00-64 cks-1 05:08 f7)

For this to work properly, it is important to match each comma-separated input message to the same number of comma-separated messages for the output, including putting the parentheses around the same number of messages for the output as was in the input:
f0 41 10 16 12 10 00 16 00-30 cks-1 05:08 f7, (f0 41 10 16 12 03 00 08 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 18 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 28 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 38 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 48 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 58 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 68 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 00 78 00-5a cks-1 05:08 f7, f0 41 10 16 12 03 01 08 00-5a cks-1 05:08 f7)

That will remap Master Volume 0-100 to 0-48, and each Part Volume 0-100 to 0-90. In my real test, I had Part 2 outputting 5a-5a (a constant 90), so the muted timpani that Ari discovered wasn't. I'm happy to report that KQ4_5.mid played without clipping, after also adding a rule tab to eliminate all controller 7 messages, by sending them to an unused port. Here's the actual output when using the examples above (Part 2-timpani is muted, but otherwise it should serve help understanding):
f0 41 10 16 12 03 00 00 01 0c 18 32 0c 00 01 00 5a 06 00 00 00 00 00 00 01 30 18 32 0c 00 01 00 00 07 00 00 00 00 00 00 01 14 18 32 0c 00 01 00 5a 0a 00 00 00 00 00 00 01 1d 18 32 0c 00 01 00 56 09 00 00 00 00 00 00 00 3b 18 32 0c 00 01 00 5a 07 00 00 00 00 00 00 00 20 18 32 0c 00 01 00 5a 05 00 00 00 00 00 00 00 24 18 32 0c 00 01 00 5a 0b 00 00 00 00 00 00 01 3a 18 32 0c 00 01 00 48 0e 00 00 00 00 00 00 75 f7

2. Program & Drum Forward now has a Velocity Multiplier value to help in supporting non-GM/GS compliant instruments. If some just seem a little quiet or louder than you are used to, just increase or decrease the multiplier. 1.00 is the default. With it, output velocities remain the same as input. I thought this might help with some non-GS/GM quiet sounds on the INTEGRA-7, but haven't remembered which yet.

3. The Unmatched rules tab now has a check box that disables Note Off Velocity for all (matched and unmatched) messages. I just was thinking that it would be easy enough to implement now, and allows simpler consolidation for multi-device maps supporting the CM-32L/CM-64 at the same time as the Sound Canvas family. Leave it unchecked, and those weird messages will go through unscathed. I think they're a relic of glitches or flaws in devices, though, and would be interested to hear of some practical use for Note Off having velocities set.

Sadly, changes 2 and 3 break the save format again, but I've updated all my included .qmr files and added a few more I've had kicking around.

Expect to always use the build instructions above (viewtopic.php?f=4&t=17790&p=18542#p18511), because I don't know a way to automate it, although that's what autoconf and automake were designed for.

Thanks for trying it, and I hope all is well! :)

First, since I forgot to mention it before now (in this thread), version 0.5.0 added the ability to remove SysEx messages when using the "SysEx Edit" type for both Input and Output. To do so, SysEx Input would contain the message to remove, and its corresponding SysEx Output message would be left blank or a space. As otherwise illustrated before, other messages can still be edited on input and output, separated from each of the two messages just described, by a comma.
To use the silly example of removing MT-32 resets, while at the same time editing GS resets to actually be MT-32 resets this could be on input (without the quotes):
"f0 41 10 16 12 7f 01 f7, f0 41 10 42 12 40 00 7f 00 41 f7"
and this on output (still without quotes):
", f0 41 10 16 12 7f 01 f7"
That would do it. Qmidiroute would only send an MT-32 reset to its output port, when a GS reset is sent to its input port.
And, the trick above still exists in the current version. Since it was purposeful, although I forgot to tell anyone until recently, I won't be removing it in any release.

Now for today's release: Version 0.5.2 is finally complete and perfect, although eventually It's pretty likely that I'll find another future necessity to add because programming this has been addicting and I'm a perfectionist. It feels so capable now, that I considered calling it 0.6, but time will tell.

Here it is:

To build it, you'll still probably want to follow this post (while swapping in the current version):

I hope this release finds everyone well, and as always, thank you for using it!

Read further for my pedantic release notes:
This time, many possible GUI improvements were noticed, added and/or fixed:
I finished implementing the output modes since I noticed them lacking, and "Offset" and "Reverse, Offset" wouldn't have worked for "GS Bank" or "GS Variation" (although I'm not likely to ever need those modes for them). indexOut wasn't my creation in the first place, but I did co-opt it for "GS Variation" (and more), so it's interesting that the prior author, in adding it, didn't notice it wasn't working either (for offsetting controller numbers, etc). Although, that use, too, seems esoteric so I shouldn't really be surprised.
A very useful new repair allows for switching the Input or Output Type temporarily, while storing user-set settings to variables that are recalled when necessary. It had been already implemented, but only for the Output Mode controls. For instance, now Pitchbend's "Pitch" is by default set to its maximum range (-8192 to 8192), and if either of the values are changed, before going to another Input or Output Type, that user-set range is restored when back on the Pitchbend type. It isn't every type that gets its own variable, though. These recall variables that I created are for when a given field's range, or use, changes. Anyway, switching types is now safer, without needing to worry about remembering the values you had set. Before, they may have been reset by simply looking at another Input or Output type's fields. The variables are in runtime memory only, though, so if you close qmidiroute or open a different qmr file, they're lost and you will still have to reset any hidden, unsaved, values again. Only fields shown on each rule, are saved to a .qmr file when you do.
An output channel range was added for the very specific use of "SysEx Edit" Input type to "Controller" Output type, so that you only need one rule to create up to 16 controller messages from just one matching SysEx input message.

Many deprecation warnings by my more recent version of the QT library (5.15.2) were resolved for future-proofing.

Drum Forwarding now matches drums based on XG and GM2 drum set controller messages being input (as well as the GS drum detection I already had in previous versions). For these controllers to be used for this drum setting purpose, though, the last MIDI initialization standard sent to qmidiroute's input port, must have been an "XG System On", or "GM2 Reset", respectively. Since SysEx is already supposed to be "Exclusive" to a vendor, though, the GS drum SysEx is used to match drums, no matter what the last recognised MIDI standard was.

To simplify multi-device single .qmr file creation further, I added a "Forward Mode" filter to the forwarding rules so that now they can match only messages based on the last MIDI initialization standard sent to qmidiroute's input port. The choices are "All" (just like it had worked before "Forward Mode" existed, forwarding everything), "MT-32, GS & GM1/2", "MT-32, GS & GM1", "GS & GM1/2", "GS & GM2", "GS Only", "MT-32 Only", "GS, XG & GM1/2", "MT-32, XG & GM1", "XG & GM1/2", "XG & GM2", "XG Only", "GM1/2 Only", "GM2 Only", and "GM1 Only". For example, an "XG Only" SysEx Edit In and Out rule will notice an XG System On message (f0 43 10 4c 00 00 7e 00 f7) and send that (or its specified edit) to the output port, and continue to send SysEx (or, as specified, edits of it) until an MT-32 Reset, GS Reset, GM1 Reset, or GM2 Reset is encountered. This feature can also be used with the "SysEx Forward", "Program Forward" and "Drum Forward" rule types, to send unedited SysEx, Programs/Instruments, and Drums to a specified output port with your chosen bank, variation, and PC#, etc..

SysEx Edit's "SysEx" text boxes can each now use an asterisk ("*") to match any of one or more bytes in a SysEx message. If you have an asterisk both in input and output, whatever is seen on input where the asterisk existed (if the rest of the message is matching), is copied to wherever the output message contains the asterisk. However unlikely useful that is, it follows traditional asterisk use on the GNU/Linux & UNIX command line utilities, so that's what I tried to duplicate. I created it simply for use as an easy match-all (or match-most) for SysEx messages, though. As an example, some XG messages mess with the SC-8850, when it isn't in XG-Lite mode (due to deleting the "XG System On" message, or if that's otherwise missing). I noticed the problematic messages all began with "f0 43 10 4c" so, wanting to remove them, now I can put this on SysEx Edit's Input, but first, here, I match "XG System On" (f0 43 10 4c 00 00 7e 00 f7) to change it:
f0 43 10 4c 00 00 7e 00 f7, f0 43 10 4c * cks-1 05:08 f7
Then on SysEx Edit's Out, I have this "GS Reset", and then a comma-separated empty message (without the quotes):
"f0 41 10 42 12 40 00 7f 00 41 f7,"
Which converts "XG System On" to "GS Reset", and the empty message simply removes all remaining messages starting with "f0 43 10 4c". The input's "cks-1 05:08 f7" doesn't actually test the input checksum, which is good (since it would be looking to match Roland's, but Yamaha's should be on their messages, here) I just like to always include it for any sitation for clarity (and since it is a placeholder which would affect output if edit replacements existed).

Here's another nonsensical example to illustrate how the asterisk replaces if it's on both input and output.
If you have this in Input SysEx Edit:
f0 41 10 42 12 * cks-1 05:08 f7
And this in Output SysEx Edit:
f0 41 10 42 12 02 88 * 11 cks-1 05:08 f7
And send it a GS Reset (f0 41 10 42 12 40 00 7f 00 41 f7), you get this from qmidiroute's output port:
f0 41 10 42 12 02 88 40 00 7f 00 11 26 f7
To begin to pick apart how that works, the asterisk on input is between the 0x12 byte and the checksum placeholder/definition ("cks-1 05:08") byte. Since the GS Reset message matches the bytes up to the asterisk in the Input SysEx Edit box (these match: "f0 41 10 42 12"), the asterisk becomes a placeholder for the further bytes read from the GS Reset message, directly after those beginning bytes that were already matched. That is, the asterisk becomes its "40 00 7f 00". The asterisk ends at the 0x00 because the Input SysEx Edit box specifies that after the asterisk, there's a checksum placeholder/definition and then a 0xf7.
Now that we've matched the GS Reset, it can be edited for output. The matched start of the message "f0 41 10 42 12", is outright replaced by the Output SysEx Edit box's bytes before its asterisk, which is "f0 41 10 42 12 02 88". Now those four previous asterisk placeholder bytes are output: "40 00 7f 00". Next, it's the 0x11 which comes after the asterisk in the Output SysEx Edit box. And finally, the Output SysEx Edit box says there's a new checksum to be written, along with the 0xf7. And sure enough, when you put all that together, you get what was suggested above: "f0 41 10 42 12 02 88 40 00 7f 00 11 26 f7"
Like I said, asterisks for SysEx replacement don't seem too useful, but it follows (as closely as I could come up with) the standard GNU/Linux asterisk command logic.

SysEx Edit Output can now be used with many other Input Types, using the SysEx range syntax as your variable in the message (such as "00-7f", which is 0-127 decimal, so perfect for most cases). Using a range means you'd want to use the "cks-1 05:08" syntax too, otherwise Roland would ignore it due to a bad checksum. If, instead, you opt not to include a range in the message, it will be sent exactly as you wrote it, without any changing bytes.
"Note" Input uses the note/key played for the variable range byte.
"Note Off" Input, similarly, uses the lifted note/key to create the range byte.
"Controller" Input uses the controller "Value" (not the CC#, but that is one of the match limiting criteria).
"Channel Aftertouch" Input uses the aftertouch (pressure) "Value" for obvious reasons.
"Polyphonic Aftertouch" Input uses the aftertouch velocity (pressure) "Value" too.
"Pitchbend" Input uses the "Pitch", of course.
"Program Change" Input uses the Program Number (PC#) "Value".
This rule's setup allows limits to how often SysEx messages are output (set in milliseconds, up to 2000ms maximum, which is 2 seconds). Setting that to 0ms doesn't limit messages at all. While limiting, messages are simply dropped, except for the last one captured, that will play either when the time limit runs out (if other messages are being sent through) or just before the next message qmidiroute receives on input is played. You can also "Remove Sequential Dups" (duplicates) by setting its box to "1", while with a "0" duplicates will always output. With it enabled to "1", for example, an Input Note, Output SysEx Edit rule would only output the SysEx message set when you play different keys in series (when you have both side's ranges allowing for it - the Note range set to, perhaps, 0-127, and the SysEx range, perhaps "00-7F"). Two presses of the C note would only register once, unless you play something else in between them. I just thought it wiser to limit SysEx repeats from bogging down devices unnecessarily, but you may decide that for yourself by setting "Remove Sequential Dups" on or off (1 or 0).

SysEx Edit as Input can be converted to Controller Output now too, since Spikey made me aware of Reverb and Chorus sometimes being set by controllers (which lead me to want GS Reset SysEx to set them). If the, now standard, range syntax is used in the Input SysEx Edit box (such as "00-7f"), the Output Controller's "Value" (restricted by the Controller Output's "Value" range) will be variably set by whatever input byte occupies its location/address in the actual input SysEx messages. Using no SysEx range means the Output Controller "Value" range will be averaged, so if you want it a certain fixed value, just set both Output "Value" range numbers to that same desired fixed number. Setting a SysEx range, from a lower value to the actual value of a byte you know won't change (such as the 0xf0 start or 0xf7 end, using either "00-f0" or "00-f7" at the start or the end of the message, respectively) would have the same effect, and then you only need to set the Controller's maximum Output "Value" range number to the chosen fixed value.

Drum Forward Output now has a "Generate GS Drum SysEx" option. When "0", nothing new is done, but when set to "1" it converts XG & GM2 controller-set drums to GS by generating the GS SysEx message for Drum enabling (or disabling) on the required channel. These SysEx messages even alternate between Roland's GS Drum Map1 and Drum Map2, so that drum program changes can provide some multi-drumset play on GS.

Finally, all of the .qmr files I previously had released have been updated to be compatible. While doing so, though, I took the liberty of adding two new conversion map files: XG-for-GS-Devices.qmr (add adding its functionality to all of the SC-8850 files), and GS-for-XG-Devices.qmr. For me, the SC-8850's XG-Lite mode seems heavily filtered, and manual conversion this way sounds clearer (and it's nice to be able to use the SC-8850 controls without making everything "Piano 1"). Although many XG files do love to sweep filters, they aren't curtailed with these manual conversions. Some XG filter sweeps are so loud on non-XG devices that I wouldn't have minded, but haven't yet found their precise cause. The INTEGRA-7-SuperNATURAL-1port.qmr converts from XG too, but was simpler to implement, since it doesn't need GS Drum SysEx to set drums on a channel.

Sorry to have released it with a glitch (especially to the one or two people who already downloaded it), but I noticed what seems a long standing one (at least it's in 0.5.1 for sure), and just fixed it, replacing the original flawed version 0.5.2. It was apparent when I tried the SC-55 variation fallback qmr files, yesterday, and was getting incorrect variations from the unmatched output. I sorted it out as soon as I could, and hope that's without introducing new bugs. So far, the edits didn't hurt anything I've tested, and I tried to test everything it could affect.

I have again released a last-night-noticed fix to a bug (which, this time, was created during my first fix release). And again, I replaced my 0.5.2 version link with it. Again, I'm sorry to the early adopters. This repair only changed eight lines, so I imagine no harm could be done, and I tested it with everything I think it applies to... Hopefully, those are not my famous last words. ;) Well, they literally can't be since I haven't described what was fixed yet, yeah!

Anyway, I noticed that XG drums on channels other than 10, were being forwarded as non-drums, but it must have also affected Program Forward (since the same four lines are used in both sections). Anyway, Program and Drum Forwarding needed their isMap() return(false) conditions corrected. I wonder if/when I'll be able to easily conceptualize the negative conditionals at the end of isMap(). If any of these conditions is true, isMap() returns false. That simple negation has lead me to much too much uncomfortable squirming.

I hope this is good news for anyone who tried it and noticed the flaws, and not as much of a chore as it is for me.

Whoops, I noticed I'd forgotten Program Change's section... It's been fixed right away, but not quite quick enough for one person. Sorry to you!‚Äč

So I have a question:
What does this thing do? I don't mean any disrespect, since you obviously put a lot of work into this program, but I really get lost in all the technobabble...
Could you give a brief summary, preferably in layman terms?
