Hi softbass,
To avoid misunderstandings and to reproduce your topic exactly, we need an short step by step description.
If i am understand you right :
- create an audio track and assign audio input from external audio device ( eg. Vocals )
- create midi track and assign midi Input from external midi device ( Motif > Midimate II (Midi Interface) > iPad > Cubasis Midi Input
- start recording midi and audio simultaneously for 10 minutes
- start playback after recording one midi and one Audio track
Result : The recorded midi data does not synchronize with the recorded audio data and vice versa.
The longer the playback, the greater the offset between the recorded midi and audio data.
Is this your usecase ?
best greetings
Jan
