I just plugged my old BCR2000 into a MacBook Pro (Ventura 13.0.1) with Ableton Live (11).
Controls are working but seems like MIDI inputs and outputs not.
MIDI data (notes) from the sequencer (clip) are not sent. LED`s on BCR not flashing so I think there is something I am missing or it just not working on the latest macOS.
Think I set up everything correctly - in Live`s preferences, all BCR`s ports are set to "Track" and BCR is in "u3" mode.
