Troubleshooting
If you’re experiencing problems or unexpected behavior from your Pro
3, here are a few typical scenarios and their solutions:
If the Pro 3 isn’t producing sound:.
1. Recall the Basic Program by holding the Transpose down button and
pressing the latch button.
2. If the problem is still there, check the following:
Volume - make sure it is set to an appropriate value
Rear-panel output jacks - make your audio cables are connected to left/right
output.
In the global menu, make sure that local control is set to on.
If the sequencer or arpeggiator has stopped running:
Check the midi clock mode setting in global to ensure the Pro 3 is set
to master or off. Or if set to slave or slave thru or slave no s/s, make
sure the Pro 3 is receiving MIDI clock.
If some of the programs sound different than usual:
In the Global menu, check scale/alt tuning and make sure it’s set to
equal temperament. Also, check the Mod wheel position. The Mod
wheel can do more than just add vibrato. Also, check the midi clock
mode setting in the global menu to ensure the Pro 3 is set to master or
off. Or if set to slave or slave thru or slave no s/s, make sure the Pro 3
is receiving MIDI clock.
If there is a ground hum in the audio output:
USB can cause ground loops, so try to resolve any grounding issues
between the computer (if connected) and the Pro 3. Or use MIDI, which is
opto-isolated.
