In addition to what @NeonSilicon said, which is probably the best way to check if the audio output is working on your board, to debug MIDI messages you can do the following:
aseqdump and connect your MIDI device to it with
aconnect. You should see incoming MIDI messages
- Launch SUSHI with the
--log-level=debug flag. This will turn on MIDI logging among the other things, if MIDI messages are received properly, you should see lines like this in SUSHI’s log file:
[2019-12-14 15:39:56.501] [debug] [alsamidi] Received midi message: [e0 0 3e 0] timestamp: 358983144
Which config / plugin are you testing? With the latest build the MDA JX10 VST2 version can stop outputting sound. We investigate the problem and, although very weird, I’m more surprised that it actually sounds in other configs / setups.
It’s using an old-school Chamberlein State Variable Filter that blows up under certain conditinos. I have the same problem with latest GCC on my X86 Linux machine. We tried several build options for the VST2 version but without any luck so far… interesting that the VST3 version doesn’t seem to exhibit the same problem apparently.
