I'm using linux-rt and PCI/PCIe devices to minimize MIDI jitter. The lower
the audio latency, the less MIDI jitter here.
MIDI can be perfectly in unison with recordings. I never had issues
regarding to jitter when using a C64 or Atari ST. PC MIDI is a wicked
thing and not related to the OS. Assumed there where no issues with my RME
card, IOW if I could use low latencies, than MIDI would be ok on my
machine, as long as it will work with linux-rt. 3.10-rts don't run on my
USB-MIDI is completely unusable.
MIDI within Linux, IOW when not using hardware MIDI, should be without
To avoid or at least reduce MIDI jitter don't use Jack1, but Jack2 with
the -Xalsarawmidi switch.
Enable HR Timer for the sequencer.
