Main Panel Controls
When Bypass is On, you can pre-set the knobs anywhere you like without
sending MIDI controller messages. When you turn Bypass Off again, nothing
is transmitted, but the knobs are now in the desired position for your perfor-
mance. When you turn a knob, the value of the new knob position will be sent
This feature can also be used to set up any of the knobs the way you want,
then send the values later using the Snapshot feature. See page 26 for more
information.
13. Snapshot
When this button is pressed, the stored current settings of all performance
controls (knobs, wheels, footswitch/pedal) are transmitted. This feature can
also be used in conjunction with the Knob Bypass control to setup, and then
send a group of MIDI continuous controllers messages at once.
Snapshot mode is always accessible, except while Edit mode is active.
14. Controller Knobs
The 16 Controller Knobs are designed to modify the sound during perfor-
mance. MIDI Continuous Controller messages are transmitted whenever the
knobs are turned (except when "Knob Bypass" is enabled).
Whenever a controller knob is turned, the current value of the knob is
displayed on the LED. Next, the letters "CC" flash on the display, followed by
the flashing MIDI Continuous Controller number of the knob.
Normal mode
Any MIDI Continuous Controller number can be assigned to any knob. See
"MIDI Controller Knob Settings" on page 35.
16 Channel Controller mode
In this mode, one MIDI Continuous Controller number is assigned to all 16
knobs and each numbered knob transmits on the same numbered MIDI
channel. This gives you control of one parameter (such as volume or pan) for
all 16 MIDI channels. See page 24.
