First, how do you have everything plugged in?

I have my keyboard’s midi out plugged into the midi in of the octatrack, and the midi out of the octatrack connected to the midi in of my synth (minitaur)

hit function + project(mixer) and in midi settings go to channel and make sure the OT’s channel (i have mine set as 16) and your keyboards midi channel is set to the same.

now click midi and then function + playback and assign the channel to the desired channel on your synth and click yes. Now you should be able to play that correspoding channel on your synth with your keyboard and record notes into the OT’s sequencer with live record mode (play+record) enabled.

I have my A4 setup like this as well, set up tracks 1-8 to voices 1-4, with 1-4 controlling a single note, and 5-8 controlling the same voices with a midi arp. great fun :slight_smile:

Let us know how it goes
