Are you sure that those are caused by the Roland device?

How many MIDI channels did you send by a single MIDI interface?
Did you use a lot of CC, SysEx or similar data, maybe unintended after
touch?

Are some events doubled?! Or are some equal events very close to each
other? Perhaps closer in sequence time than the length of MIDI
jitter could be?

If using a lot of CC or similar data, how many ticks are you using with
your sequencer and do you quantise this data and or reduce it?

It might help to disable running status by the sending device,
unfortunately, AFAIK it's not possible to disable running status by
Linux.

Did you test different MIDI interfaces?

I seriously doubt that a Roland synth has a broken MIDI implementation.

Most likely it's an overloaded MIDI interface and/or a bad MIDI
interface.

If not, more likely the issues are cause by the Linux computer, than by
a Roland synth.
