I have the same problem here, playing with an usb
keyboard.
Sometimes you probably have "clicks" (digital saturation) too.
Bristol has had these issues although they were supposed to have been
iron out in the later releases. The cause of the clicks was largely
due to voice reassignment with mono synths fixed by implementing a
different note assignment method (note preference with droning) and
the sticky notes were due to scheduling issues between threads fixed
with a jack ringbuffer message passing method.
Now a lot of the distributions are still packaging bristol-0.40 which
is a couple of years out of date. If you have newer versions then I
can work on some debuging with you, if you don't have 0.60 then it
would make sense to try that first.
I cannot rule out other issues but lets start with the versions you
have and take it from there.
Kind regards, nick.
You're right, I didn't mention system info. I have version 0.60.7
running on Archlinux, standard kernel. Jack is running on laptop
built-in audio card with:
/usr/bin/jackd -r -t2000 -dalsa -dhw:0 -r44100 -p2048 -n2 -Xseq
I found the hanged note stops if I change the midi channel in bristol.
Not sure if the note is still there playing when I change back to the
original channel, I'll try it next time it hangs.
