the usb hosting works the same as midi din... assuming you the device you are connecting is usb midi class compliant.
if you use midi/in/monitor ... do you see midi messages?
if not, try different usb cables,
also if available use the controller with a power adapter rather than relying on usb power
Hi @mlbstrd,
The Midi USB is the vertical usb slot (type-A receptacle).
As @thetechnobear said, it should work like the DIN inputs with the midi objects you already use (both inputs are merged).
Make sure that the usb cable you use between your keyboard and the Axoloti works fine (some mini to type A cables are designed to charge phones and are power only, without data wires).
Actually that's not strictly accurate...
midi/in objects ( and cc assignment) don't care about the midi source. ie they will handle from any source.
But... you can filter from a particular midi source by using a subpatch, then you have the choice to choose USB device/USB host/din.
