Hello, I am trying to connect my old Roland PC-200 Mk II to my Mac via a Roland UM-ONE USB/MIDI interface. I have successfully managed this before, but now I don't seem to be able to get it to work.
When I initially switch the keyboard on I can see input lights on the interface when I hit a key, but, after a short while (less than a minute) the MIDI/SELECT light on the keyboard comes on and I then don't get any indication on the interface.
Even before the MIDI/SELECT comes on, I don't seem to be able to get any sound out of the Mac, but clearly the stuck MIDI/SELECT is the first problem to sort out.
I would be grateful for any help. Anyone experienced this before?
