There might be another strange behaviour. IIRC when I recorded audio
from external MIDI devices (when I used my USB MIDI in the past), some
waveforms were recorded, before the MIDI event should be played.
I need to test this again.
Btw. I used Qtractor, that didn't had a latency compensation that might
work bad, hence all MIDI events should have (positive) delay, but
negative delay for recordings. When doing the test today I even didn't
notice if always the virtual or the external drum sounds were later or
if it does change, far less that I was able to hear if there was just
delay or negative delay, I didn't record anything and it's hard to hear
those details, it's easier to hear that something isn't in timeing.
ALSA MIDI thru definitive has audible latency. I played live testing
this. I can't say if it was stable latency or jitter.
Do you know the psychological effect, when you try to sing, while you
just can here your vocals with much delay?
You will lose timing.
amidiplay can play MIDI files for two MIDI channels? Note! It's not easy
to notice this jitter, when there isn't a reference, e.g. you try to
groove live or a bass by a software synth should be in sync with
external drums. Just listening to one source with jitter just works for
a short time, than you become unable for hours to notice a bad timing.
But you always will notice this issues for real work, e.g. when first
recording an external bass and than recording the external bass drum
Here it's Wednesday too ... when I said I've got time from Friday to
Sunday for Linux only, I was talking about the da after tomorrow :D.
Btw. I assume that the max. time difference on earth won't be days ;).
A thunder-storm put a spoke in my wheel .. I shouldn't be online now :D.
