Troubleshooting

If you're experiencing problems or unexpected behavior from your
Prophet-5, here are a few typical scenarios and their solutions:
If the Prophet-5 isn't producing sound:
1. Recall the basic preset by holding down
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
• In the
globals
If some of the programs sound different than usual:
• In the
globals
NOL. Also, check the Mod wheel position. The Mod wheel can do more
than just add vibrato and maybe be affecting filter cutoff.
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 Prophet-5. Or use MIDI,
which is opto-isolated.
If the Prophet-5 is behaving erratically:
• This is almost always caused by a MIDI feedback loop. Make sure
that any MIDI Thru functionality is turned off on the MIDI interface/
hardware or in the MIDI software application. Disconnect all Prophet-5
MIDI connections (MIDI and USB cables) and see if the problem
persists. You can also monitor the MIDI traffic with MIDI Monitor
(Mac OS) or MIDI-OX (Windows) to see if the Prophet-5 is being
overrun with duplicate messages.
