The setup: Octatrack and OP-1 connected via iConnect audio/midi box.
I want to sequence the OP-1’s synths with the Octatrack’s MIDI arpeggiator, but I also want to use the OP-1’s keyboard to play the Octatrack.
The result would be that I hold a chord on the OP-1’s keyboard, and this chord is arpeggiated by the Octatrack, which then plays the OP-1’s synth. Is this possible?
So far I have sequenced the OP-1’s synth from the Octatrack, and used a keystep as the external keyboard. But I’d rather not use the extra box.
FWIW, I have the OP-1 and the Octatrack’s midi both set to ch 13. The autochannnel is 11.
Every time the OP-1 receives a note via MIDI or plays a note via the keyboard, it gets sent THRU its MIDI OUT channel; so I think you may have some crazy loop back issues if you try connecting it that way.
I have a similar set up, but my USB MIDI host is a RK-006 - and every time I send a note or play the OP-1, the host lights up, indicating that a message is being sent to the Out Port.
Your best bet is using the OT as the master controller - use the OT’s keyboard to trigger the arp; and do not connect the OP-1’s MIDI Out port to the OT.
That sounds workable, although if I use the OT’s keyboard to trigger the arp, I can’t hold a trig at the same time. I like to hold a trig and play a chord to lock it to that trig.
You got me thinking though. Perhaps I could use the iConnect box to remap the OP-1’s ch.13 output to ch.11 (autochannel).
That’s if the OP-1 even outputs midi notes when in synth mode. I should check that. (EDIT: Yes, it does).
Update: looks like this will work. I just hooked the OP-1 up to a midi monitor app on my iPad, and in audio mode, it outputs midi keypresses, but does not pass through notes triggered by incoming midi.
That should hopefully mean I can remap the OP-1’s out to autochannel, and avoid feedback loops. In theory that’s set-and-forget, too.
I tried remapping the outgoing midi from the OP-1, as mentioned above, but in the end it’s not necessary. I just set the OP-1 and the target MIDI track on the Octatrack to the same MIDI channel (Ch 13 in this case).
The result is that the OP-1 sends notes to the Octatrack, even with the OP-1 in normal synth audio mode. You can use it to lock chords to trigs, or live record.
Also, when you play the Octatrack pattern back, it sequences the OP-1. When sequenced externally like this, the OP-1 does NOT send out MIDI notes. This is the key, and also the reason that remapping is not required.
I hooked up a midi monitor to see what was going where, and it confirms that the OP-1 is behaving as described above.
