Forgot about this, and it just arrived at my front door! 
I bought this (I think?) as a USB host between the OP1 and everything else - also hoping to use it as a multi fx of some variety. Any advice on where to start? is the Ax community good?
Aaaaaand it looks like the Ax forum is down xD I guess that’s my first attempts fruitless!
I posted the patch in the axoloti appreciation thread. I may grab a second.
Lots of useful features and it can do MPE for my linnstrument (and the roli seaboard/k-board types).
