Yes :). > I had presupposed > before that your MIDI device was triggering *after* your software > synth, but it occurs to me that it might be the other way around. Do > you hear the audio from your software synth first, or from your MIDI > device? I can't say it today, now I do some office work. I had the impression that it might vary. Sometimes the virtual drum sampler and sometimes the standalone drum sampler was played earlier, I need to check this ASAP. For older tests with my USB MIDI device it was exactly that way, that jitter had positive and negative delay. At least the recorded waveforms of external MIDI equipment (when I used USB MIDI, now I'm using PCI MIDI), were recorded by Qtractor, before theoretically the MIDI event was send ;). Note! Qtractor had no latency compensation, all recorded audio of external MIDI instruments should have (positive) delay, but negative delay. - Ralf PS: Today I just listened to similar sounds and didn't notice if there was negative delay or what drum sample might be played before the other, I just noticed that they were not played in unison. _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
