The App should in theory work with any Midi enabled device, but there are a few controllers which don't seem to work as expected. This is a list of controller surfaces that users have reported on. If available, I'd also recommend you install the editor software for you controller to be able to customize the buttons, in some cases it's needed in order for all functions to work (notably feedback). I'll link them on the names in the list. If you are using a device which is not on the list, leave a comment below.
