There should be improvements to MIDI under linux/alsa (thanks to
updated by Gary Scavone in RtMIDI). The first thing to try (if you
haven't already) is to lower the real-time audio buffer size using the
> chuck --bufsize128 foo.ck
Try different powers of two to hopefully find a good balance between
latency and stability. If that doesn't work out, then we will proceed
with more tests...
