Cubasis 2.4.1 - IAA instrument issues

Hi All,

I am not sure if this has already been discussed. I tried to find a topic like this, but didn’t find one. Apologies if this is a known issue already.

I notice that when i try to create a midi track that uses an IAA, such as Model 15 or say zMors Modular, this works for a little bit, but eventually the IAA instrument will stop responding within Cubases. To fix it, I will have to manually switch to the IAA app itself and force close it. Then, I’ll need to go back to to the Cubasis midi track and toggle the Inter-App instrument. That Inter-App will automatically open up again, and when i go back to Cubasis, the Cubasis keyboard will now be able to play that app.

I’m running Cubasis 2.4.1 on a 12.9" iPad Pro, in case the hardware matters.

Anyone else have this problem?


I have the exact same problem. Could you solve it?
