ive looked into this linux issue a bit today with the help of andrew
burnson. i do indeed hear the "drift" on an (emulated) linux but i
do'nt yet know the cause or the cure (if any). its not Grace's
scheduler per se: even if i spool midi messages out without using the
scheduler or processes whatsoever i get the drift . as far as the
scheduler lloop goes im able to improve it a bit by not 'waiting' but
its not a huge improvment. the problem seems more basic, but im not
sure if its Grace, or juce, or what. increasing the process priority
of the Grace app itself and/or its individual threads doesnt seem to
help. note that even with the drift you can still write midi files
fine and you can also work with clm audio files, its just the realtime
midi as far as i can tell.
ill keep poking at this but any fix will probably not be in the next
release (today or tomorrow)
