Hi All,
I am dealing with an issue with Bristol where the B3 emulator uniquely
exhibits stuck notes. None of the other emulators seem to show this problem
and all debuging to date indicates that this is not an external issue such
as lost MIDI messages, etc. The B3 has a lump of code that emulates all 92
tonewheel whenever a key is pressed, it chews up a nice amount of CPU and
this may be related to note event management sequences that might be buggy.
Now the guy who reported the issue sees it regularly, he just needs to play
a sequence of notes quickly and eventually one will stick on until pressed
again. For the life of me I cannot reproduce this on my dev system, after
hours and hours of playing.
The bristol B3 is perhaps not the most popular example of hammond emulators
but has anybody seen this?
i have some extremely limited and utterly circumstantial evidence that
the ALSA sequencer can cause this. Check the comparative versions of
his and yours. I stress: I can't prove this either, I've just seen
vaguely similar behaviour that given a brief debugging seems to be
caused by the sequencer at some level. Relevant?
