Regarding the MIDI clock sync trick (click track), although I suppose it applies to all midi control between Gadget and Audulus:
okay so as usual when you get stuck, sometimes walk away and come back and it works.
@robertsyrett is right. When you are sending midi out of Tapei, and you also have Audulus running, you can just select Audulus as the destination within the Gadget app. You select this when zoomed out in this screen.
If you are running Gadget and Audulus an IAA plugin within AUM, you select AUM as the destination. In AUM itself, you also use the routing matrix to send the signal from Aum to Audulus.
If you hit play in Gadget, the sync pulse will blink in the matrix window above, making the routing easier.
This is a single device method.
