Appendix D: Troubleshooting and Support
If the Prophet X 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/hard-
ware or in the MIDI software application. Disconnect all the Prophet
X’s MIDI connections (MIDI and USB cables) and see if the problem
persists. You can also monitor the MIDI trafc with MIDI Monitor
(Mac OS) or MIDI-OX (Windows) to see if the Prophet X is being
overrun with duplicate messages.
If the Prophet X doesn’t seem to respond to its controls:
Make sure local control is on in the global menu.
If MIDI System Exclusive data is not transmitted/received:
Make sure that the midi sysex cable setting in the global menu is set
to usb or midi depending on which you are using to transmit or receive
MIDI messages.
If the Prophet X plays out of tune:
Check the master coarse and master fine parameter in the global
menu to make sure they are both set to 0.
If the pitch or mod wheel doesn’t go to full range:
Recalibrate the pitch and mod wheels. See “Calibrating the Prophet X”
on page 117.
If the touch sliders don’t go to full range:
Recalibrate the touch sliders. See “Calibrating the Prophet X” on page
117.
If the lter sounds strange or out of tune:
You may need to retune the lters. See “Calibrating the Prophet X” on
page 117.
