Here's how you do it:
Setup Ableton:
- connect the BSP to your computer
- go to Ableton Preferences -> MIDI Sync and in the Midi Ports table enable Track for the Arturia Beatstep Pro output (attachment picture 1)
- create a MIDI track in Ableton and set the output to Arturia Beatstep Pro and the channel to 1 (attachment picture 2)
- Create a MIDI sequence and add some notes to play
Setup the Beatstep Pro:
- set MIDI sync to internal (int), this is important, if the Beatstep Pro sequencer is also running, it will not forward MIDI-to-CV from external MIDI input
- Select sequencer 1
- set sequencer 1 MIDI channel to 1 (chan + step1)
Setup your CV hardware:
- connect sequencer 1 pitch/gate/volume CV outputs to your modular hardware
- it's a good idea to verify the connection by playing back a sequence from the Beatstep Pro directly.
If everything is fine your modular should be sequenced from Live by playing back the MIDI sequence.
