Can anybody help? I want to use Kamata!Looking at the guide (since I don’t own an OPLab) you probably want to set it to Mode 3 “Dual Mode”. The Octatrack would go to the Midi-In I suppose and the iPad to the (smaller) UBS Device port.
I think you should get away with the Octatrack being the Clock master. In the settings of the Gadget make sure you have “Easy” selected for the Midi Input (you can probably get more fancy later) and the clock either on “Auto” or “Ext”. I’d start with “Auto” as well.
On the Overview panel of Gadget where you see all your instruments there’s a small Midi button below the instrument fader. If it’s yellow that instrument should receive Midi. When Gadget detects external Clock signals it’ll automatically replace the Stop and Play buttons with a message to indicate external sync.
If you can’t get it to work this way then try forcing external sync via the Gadget settings. If that fails you might want to invest in any of the Midi plumbing apps. I’m using Midi flow which allows you, beyond a lot of other stuff, to monitor what’s going in and out of connections. Very useful.
Btw: If Mode 3 works for you, I think you should be able to attach the OP-1 to the second UBS Host interface on the OPLab.
