As ever, could be many things.
1) Do a MIDI/Get command on Vsig. If the BUSY light on the 7600 flashes, go to step (2)
If it does not flash, it could be one of:
bad cabling – try reversing the cable connections – sometimes things are labeled "IN" when they mean "to IN", etc.
bad MOTU setup.
bad Vsig Preferences/Comms setup.
SETUP/MIDI/MIDI is disabled on 7600.
2) If it does flash, and you get activity on the 7600 screen go to step 3
If no screen activity on 7600 it could be one of:
SETUP/MIDI/System Exclusive is off.
SETUP/MIDI/Device ID is not 1. Check MOTU for same.
3) If you get 7600 screen activity but nothing on Vsig, it could be one of:
bad cabling.
bad MOTU setup.
bad Vsig Preferences/Comms setup.
