Carla patch changes not handled properly using gig files #140

Closed asbaklm closed 6 years ago

asbaklm commented 10 years ago

I tried some gig files in Carla and patch changes in the editor when selecting from "Program" aren't working properly (don't seem to change, or they change somewhat but appear to keep playing the original patch + new patch overlaid?). These work ok when using Qsampler.

Changing patches might not be working so well in the current code. I'll give it a check before the next beta release.

Got it, many thanks for taking a look =)

Can you check if this issue still happens? (It should be fixed now) Thanks.

I see this is an old bug but it appears it's still present as I'm having the same problem using Carla-Rack as an LV2 plugin in Qtractor.

Upon changing "Program" for a loaded gig, the name will update correctly but the actual sound will not - it remains that of the initial patch. After re-loading the session in Qtractor, Program's name returns to the initial patch (the sound is the initial patch too). I've tried various gigs with the same result, though I have had the sound change correctly on a handful of occasions (around 5% so far) and can't ascertain why it worked correctly on these occasions.

FYI, in case it's relevant, upon changing Program the following appears in Qtractor's Messages window:

Carla assertion failure: "sendGui || sendOsc || sendCallback" in file ../backend/plugin/CarlaPluginLinuxSampler.cpp, line 467

And, on closing Carla's GUI, the following appears:

Using "carla" theme Carla 1.9.6 (2.0-beta4) started, status: Python version: 3.3.5 Qt version: 4.8.6 PyQt version: 4.10.3 Binary dir: /usr/local/lib/carla Resources dir: /usr/local/share/carla/resources Carla assertion failure: "pData->pipeRecv != INVALID_PIPE_VALUE" in file ../../utils/CarlaPipeUtils.cpp, line 1013 Carla assertion failure: "pData->pipeSend != INVALID_PIPE_VALUE" in file ../../utils/CarlaPipeUtils.cpp, line 1094 Carla assertion failure: "pData->pipeSend != INVALID_PIPE_VALUE" in file ../../utils/CarlaPipeUtils.cpp, line 831 [the assertion failures are variously repeated below this]

The patches do appear to change correctly when running Carla-Rack in standalone mode. Save/load state are also working.

I'm running Carla-Rack 1.9.6 (2.0-beta4) from git, a recent Qtractor git version (0.7.7.17) and LinuxSampler 2.0.0, on opensuse 13.1.

I suspect that this is happening to me with maestro_concert_grand_v2.gig from http://linuxsampler.org/instruments.html . The first program does not have sustain pedal release noises, and the second one does, but when switching to it there are still no sustain pedal release noises. This is with the latest 2.0-beta7.

geckolinux commented 6 years ago

To follow up on my last comment, it appears that it is now working correctly with the 2.0-beta7 in my distro's repo, my previous comments were with the precompiled binary tarball supplied by falkTX/Carla.

falkTX commented 6 years ago

what version of libgig do you have installed from opensuse repos?

geckolinux commented 6 years ago

libgig8 4.1.0

falkTX commented 6 years ago

Gig file support was removed from Carla, due to many issues regarding linuxsampler (the library used for gig sampling). I'm closing this bug, sorry for the inconvenience.

geckolinux commented 6 years ago

Ooh. I'm sorry to hear that. I'm surprised that GIG sampling has been so troublesome, as I have been using GIG soundfonts with Carla since 2.0-beta7 with good success. Even the patch changes work well now.

The reason why I think that GIG support is important for Carla is because LinuxSampler/Carla are the only synthesizers I can find that have realistic sustain pedal behavior.

falkTX commented 6 years ago

Issue was mostly with SFZ files it seems, but anyway, you can just load linuxsampler within carla and control it with qsampler. Or if you just use gig files, use the ls16 plugin.

geckolinux commented 6 years ago

Thanks for the reply.

I really don't like the qsampler interface, and ls16 doesn't appear to be available for my distro.

What about adding back the GIG support under Experimental Features?

falkTX commented 6 years ago

I really rather not do that.

For ls16, you can use my sources or even the binary. See https://launchpad.net/~kxstudio-debian/+archive/ubuntu/plugins/+sourcepub/3810796/+listing-archive-extra (deb extraction is need on that case) the plugins as I build them are self-contained, so no external libs necessary.

geckolinux commented 6 years ago

Thanks for the link. I tried extracting the dssi directory to /usr/local/lib64/dssi and setting that path for searching DSSI plugins in Carla. But the scan for new plugins doesn't seem to find it. When running the scan I can briefly see /usr/local/lib64/dssi/ls16.so flash across the scan progress, but even after running Carla it says no DSSI plugins are available.
