Sure! I’m using an iConnect Midi USB–>DIN, and always make sure to connect both IN and OUT to the Minilogue. It’s doubly fun to then route the audio out of the ML and back into Dunes. I try to always make sure that I’ve got the midi device I want to use mapped to #1 in the SYSTEM menu. If it’s still not working, sometimes it’s helpful to modify the script by changing line 25 to read local midi = midi.connect(1).
But please take that last suggestion with a grain of salt because I am, like, way out of my league once we start diving into code.
