It was before the OS update. I don't remember doing anything special on the iCM4 or the Organelle. It just works. My iCM4 was set to send everything from the iPad and the Computer out from the two 5-DIN outputs.
I can send MIDI to the Organelle and to my guitar pedals from the iPAd at the same time, AND also send MIDI to the pedals from the Organelle. I can also connect my QuNeo over its MIDI Host box to the iCM4 and send MIDI from it to the Organelle and the iPad.
I will resume using it with the Organelle next week. I'll report back if anything changed after the OS update, but I don't see why it should.
