so then in the AMS (Audio Midi Setup) on the mac you should create and ‘connect’ the keyboard to the 128…with the virtual cables. then you should see the pc200 as a midi input…if you want you can pm me and i can show you over a video chat…Yes I am using a Mac Actually exactly like yours. I just have 32GB RAM though. I have an old MOTU MIDI Express 128. I am just using Ch.1. The PC-200 OUT goes to the MOTU with the USB from the MOTU to Mac mini. The MOTU ch. 1 light blinks but, in MIDi or Controller in Luna nothing shows up. Thank you for your response.
add 3 hours to that i’m on the west coast usa. PSTI am afraid I will need you to walk me through it. I have everything up I think but, I can't draw the cable connections. I am in Switzerland so I am 6 hours ahead EST. I have tomorrow completely free and Tuesday is also free. Thank you very much for your help.
