If the Pro 3 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 Pro 3 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 Pro 3 is being overrun with duplicate
messages.
If the Pro 3 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 Pro 3 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.
• You may need to recalibrate the oscillators. See “Calibrating the VCOs
and Filters” on page 126.
If the pitch or Mod wheel doesn’t go to full range:
• Recalibrate the Pitch and Mod wheels. See “Calibrating the Pitch and
Mod Wheels” on page 126.
If the touch slider doesn’t go to full range:
• Recalibrate the touch sliders. See “Calibrating the Pitch and Mod
Wheels” on page 126.
If the filter sounds strange or out of tune:
• You may need to recalibrate the filters. See “Calibrating the VCOs and
Filters” on page 126.
