I had the same problem to start with, until I figured out that it was
halting due to an inability to open the sound device that it was trying
to open:
...
spawning audio thread
bristolAudioOpen(plughw:0,0, 44100, 256, 1200008)
audioOpen(b7f9a200, 0, 1024): plughw:0,0
opening device plughw:0,0, flags 0000000d
open playback on plughw:0,0, pre 8
Could not configure playback period size
period size is -1208655184
Problem opening audio device plughw:0,0, exiting audio thread
...
On my system, audio "device" 0 is a virtual MIDI device (for some reason
which escapes me at the moment). I have audio output devices (soundcards,
the first built-in, and the second an add-on card) at "1,0" and
"2,0".
For some reason I'm not able to get Bristol to use the add-on card at
2,0, though other audio applications (some through JACK, others not)
are able to.
Bristol is working for me if I add "-audiodev plughw:1,0", though its
output isn't very loud (compared to other audio applications), which I
worry about because I would ideally like to use it in lieu of hardware
synthesizers, and I'm as yet unable to get any MIDI control of it. :-(
I hope I've helped ... Can anyone help me control Bristol via MIDI?
