I'm having the same problem. For all the millions of things one can do with a controller like this, the one thing that brung me here a few hours ago is the need to add a real or virtual mini-keyboard to my DAW so I can play high-pitched violins, piccolos etc. on the top octaves of my 49-key controller while keyswitching their articulations way down at the typical C1> range with MIDI Designer. So far, all I've come up with is buttons. But they have to be toggled rather than hit once for each keyswitch, as one would do with a regular synth keyboard. Is there no simple MIDI keyboard simulation available for this app?
