Looks pretty, but i didn’t have a chance to try it because of some bug that doesn’t allow me to change MIDI output, so i can’t output the signal out of it.
Those are some wild shortcuts :D if it doesnt work due to those you can still click on the menuitems and also on the small buttons [M] for refresh and [</>] to switch between devices. If devices cant be detected at all and a restart doesnt help either it might actually be broken sadly :/ what os do you use in that case? and to which device are you trying to connect?
Hope it all works out and thanks for messaging :)
