I recorded audio simultaneous with the MIDI from my Motif into Cubase. My audio latency is theoretically 5.8 msec, (though according to Cubase, the input latency is 6.531 msec, ). As expected the audio straight from my Motif appeared consistently after the MIDI: 2 msec, 5 msec, 5 msec, and 4 msec later. Assuming consistent input audio latency of around 6 seconds then, it seems the MIDI was recorded (inconsistently) between 1 to 4 msec after the key was hit.
Is this inconsistency, “MIDI jitter”?
And why is the calculated latency of 5.8 msec (256 samples, 44.1K) different than Cubase’s reported 6.531 msec? And why does Cubase report different latencies for input (6.531 msec) vs output (6.485 msec)?
