MIDI queue drift correction is all about adjusting the ALSA(-MIDI) Sequencer skew rate to minimize the drift to JACK(-audio) frame time; although it doesn't really matter to when all processing is done internally, inner to qtractor engine, which btw is always sample-accurate, it's more of a concern specially to external (ALSA-)MIDI event streams in the long run, when the (JACK-)audio and (ALSA-)MIDI clocks surely and increasingly drift away from each other.
re. What does MIDI queue drift correction
hi,
MIDI queue drift correction is all about adjusting the ALSA(-MIDI) Sequencer skew rate to minimize the drift to JACK(-audio) frame time; although it doesn't really matter to when all processing is done internally, inner to qtractor engine, which btw is always sample-accurate, it's more of a concern specially to external (ALSA-)MIDI event streams in the long run, when the (JACK-)audio and (ALSA-)MIDI clocks surely and increasingly drift away from each other.
hth. cheers
