Hi John1289,
Great to hear BM3 works as expected via IAA Audio at your end as well.
Our engineering confirms, that IAA MIDI seems not supported by BM3. Will try getting in touch with them to make them aware of the issue.
Here comes the technical background information from our engineering:
BM3 lists itself as an IAA instrument, but in reality it’s only an IAA generator.
IAA instruments receive MIDI through IAA, which is not the case with BM3. If you add a MIDI track and assign BM3 as an instrument, playing on the Cubasis keyboard will not produce any sound.
In the video, the CoreMIDI connection between Cubasis and BM3 is configured in the inspector. CoreMIDI is not related to IAA in any way.
To record an IAA generator like BM3, is to set the MIDI track to “No instrument”, write the notes on the MIDI track, set it’s CoreMIDI output to BM3 (as shown in the video). Then add an audio track, open the Routing panel in the inspector and select Inter-App / BM3 as input (instead of mono). Recording audio on this track will result in an IAA recording of BM3 playing the (CoreMIDI, not IAA MIDI) notes from the other MIDI track.
Best,
Lars
