RE: Patch for some Roland devices' USB digital audio
Sorry, I should've realized that embedded plaintext patches are preferred, as I've been on the linux-media list since forever. This should improve the ability to find the pertinent devices too, so here it is again:
A couple days ago, I found this excellent informational post, and that Mike Oliphant's patch is in mainline now: http://blog.nostatic.org/2020/01/getting-boss-gt-1-effects-processor-to.html
Since I was fairly certain it applies to the Roland devices I own, I added my USB IDs. Wonderfully, now USB audio capture seems to be working perfectly from the three devices I can test: the INTEGRA-7, Boutique D-05, & VG-99!
I don't know if the D-05 and VG-99 have digital audio playback/output, as I only tried it with the INTEGRA-7. It does work, but only when the INTEGRA-7's "Sampling Rate" is set to "44.1 kHz" and "Ext Part Source Select" is set to "USB AUDIO".
I searched a bit for other Roland devices people have had USB digital audio issues with over the years, and took the liberty of adding them to the patch too. Likely there are still many more, especially in the Boutique line, but I couldn't find their USB IDs.
I hope this can be added to the mainline kernel too, as this support should help many that have struggled. I, certainly, have been hoping somebody would figure this out for quite a while, and even bought a USB through/monitoring device to try to develop it myself (sadly, the software supporting that has its own bugs, so I probably should've just used wireshark). Suffice it to say, I'm quite happy to have this figured out, and to not have to delve into stuff I know nothing about! :)
Thanks,
Lucas

Soon after posting it, I realized that output inclusion is implied for anything using USB implicit feedback. So, now I've tested that on the "Boutique" D-05 and VG-99. They seem to be working as expected. There is one caveat, namely the D-05's analog outputs aren't as clean as the other two devices, with little quiet occasional clicks sounding something like dust on an LP record's play. Possibly that can be chalked up to it having only 1/8" minijack connections, but I suspect something more driver-related as I've not noticed it during use as a synthesizer. Its firmware version is "1.02(1033)," so not up-to-date which may mean it's just the hardware itself, but I've decided not to risk any changes with it yet. If I knew I could revert it, that would be another story. Also USB captures from it, play perfectly cleanly on my usual sound device, the Edirol UA-4FX.
You probably already know this, as someone coded them, but here are the commands I've had to use for format compatibility with these devices:
D-05: arecord -D hw:Boutique -f S32_LE -c 2 -r 96000 ./file.wav aplay -D hw:Boutique -f S32_LE -c 2 -r 96000 ./ile.wav INTEGRA-7: arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 96000 ./file.wav (then change MENU->SYSTEM->SOUND->Sampling Rate to 44.1 [kHz] (otherwise its 96[kHz]) and change MENU->SYSTEM->SOUND->Ext Part Source Select to USB AUDIO) arecord -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav aplay -D hw:INTEGRA7 -f S32_LE -c 2 -r 44100 ./file-44100.wav VG-99: arecord -D hw:VG99 -f S24_3LE -c 2 -r 44100 ./file.wav aplay -D hw:VG99 -f S24_3LE -c 2 -r 44100 ./file.wav
I have another of the devices I added, with the patch, arriving soon (the R-26) so I'll have to get back to you with how that works too.
Thanks to anyone looking into adding this,
Lucas
