Midi trigger for Koala Sampler / USB-C Connection

Post by Go4Sail » Thu Mar 19, 2026 2:45 pm

Hello everyone,
after numerous attempts to connect the Aerodrums 2 to my smartphone and trigger my own samples in the Koala app, I realized that I do need a bit of help after all. So far, I’ve only managed to get MIDI control messages to arrive in Koala once. Unfortunately, it’s not working at the moment, and I’d like to know about your experiences connecting the AD2 to a smartphone via a USB‑C cable.
My cable is OTG‑capable and has so‑called e‑marker chips, which should actually support hosting.

I’m happy about any tips!

PS:
For the time being, I’m using my Arturia MiniFuse 2 to access the MIDI data via the host function. This works remarkably well, although it would be nicer if the smartphone could connect directly to the AD2 control unit. Triggering and playing back (and controlling) the beats is already quite feasible with this workaround.
