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 traffic 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 filter sounds strange or out of tune:
• You may need to retune the filters. See “Calibrating the Prophet X” on
page 117.
