Thanks for the quick reply Phil. Tried that and doesn't seem to work. Here are my global MIDI/Tempo settings:
Midi Base Channel - 1
Midi Thru - Off
RX Midi Clock - Off
TX Midi Clock - Off
Tempo - Preset
BPM - 120
USB Midi - On
MIdi PC RX - Both
Midi PC TX - Off (which is, I think, the one you suggest turning off above)
Cheers
