MIDI keyboard compatibility

hello! I don’t know if this is the best place to ask, but I’m very new to synths and thought the organelle would be great as a portable keyboard using a 61 key MIDI controller. I hooked up my 32 key M-Audio KeystationMini MK3 and it worked fine, but when I plug in my Korg microkey261 it doesn’t. The organelle recognizes it as a controller and it seems to have power, I even tried it with a powered bus, but it doesn’t work with any of the patches I tried. does anyone know what this issue could be? thanks for any help!
