Midi notes from IAC Driver are not recording

When using one DAW and IAC to send MIDI to Cubase recorded notes all snap to transport start position. Audition and Performance is not effected.

This only seems to be an issue with DAW to Cubase. I use IAC and NativeKontrol PXT to control Cubase via Push and there’s no issue.

Can a MOD move this to the BUGs section?

It seems to be a ReWire issue with Cubase - IAC MIDI ports work as expected sending DATA between DAW and Cubase when not ReWired.

IAC also works fine with Reaper and Live in ReWire.

Similar problem here.

My scenario: I’m generating MIDI from a custom software (no ReWire), sending it to a IAC MIDI port, then route that into Cubase. Audition is fine, but recording collapses all notes to start position.

This is five years later but did you ever find a solution? I have the exact same problem in Cubase 11. (External software sending MIDI notes via IAC; all notes end up at time point zero).
