DECAY

PARAMETER
VALUE
Turn VALUE to adjust the selected parameter.
The display will show parameter values while the
knob is being turned. A decimal point in the
display indicates changes have been made
since the last store operation.
The PARAMETER button cycles the selection
of DECAY, DELAY and FX LVL. A lit LED
indicates the currently selected parameter.
Editing an Effect
The VALUE knob is always active, and will
adjust whichever parameter is indicated by
the display LEDs. The first turn of VALUE will
display the current parameter setting. Sub-
sequent adjustments will increment or dec-
rement parameter values along their entire
range (1-16).
The decimal point on the display will light
when a parameter is adjusted to indicate that
the effect has been modified since the last
store operation. If no further adjustments are
made with VALUE, the display will revert to
showing the number of the currently running
effect. The edit indicator will remain on until
the effect is stored, or until changes are lost
by selecting another effect with the REGIS-
TER/PRESET knob.
For each preset, three parameters have
been made available for front panel control
through the DECAY, DECAY, and FX LVL
controls. Control over these parameters is
simple press PARAMETER/LEARN to
select a parameter, then adjust it with the
VALUE knob. All parameter settings made
from the front panel can be stored with the
effect.
