...but no, AFAIK the issue you experience isn't a known issue. Yes, USB
MIDI is known to cause more MIDI jitter, than other MIDI interfaces.
You could reduce MIDI jitter by using a rt-patched kernel. Regarding
latency, mainline kernels, such as the Ubuntu lowlatency kernel, are
not optimal, it's better to build a rt-patched kernel, since this also
reduces MIDI jitter.
