EXPRESSION PEDAL USE AND SETUP
The Grand Canyon accepts an expression pedal with TRS plug or control
voltage (CV) on a TS plug at its EXP phonejack. Please see page 15 for
specifications on acceptable expression pedals and voltage range for the
Grand Canyon. An expression pedal has one function when the EXP MODE
Button is off, and a different one when the button is on.
EXP MODE Button Off – When the EXP MODE button is not lit, the
expression pedal works like a volume pedal placed before the Grand
Canyon. The expression pedal controls the level of both the signal going
into the delay effects block and the level of the dry signal, generating
expressive, swelling delay effects. When the EXP MODE button is not lit,
any Expression Settings (see below) are disabled.
EXP MODE Button On When the EXP MODE button is lit, the Grand
Canyon’s Expression Settings are enabled. You can create an Expression
Setting for each Delay Type where you assign the knobs you want to
sweep and customize each knob’s range and direction. Any parameters
that are assigned to the expression pedal will be taken over and the
current knob positions will be ignored. After you create an Expression
Setting for a particular Delay Type it remains in memory until you change
it again, even if you remove power. In addition, when you save a preset,
the current Expression Setting for that Delay Type is also saved.
Note: if the EXP MODE button is turned on while no expression pedal is
connected, any parameters controlled by the expression pedal will be set
to the saved toe position of the Expression Setting.
