Storing parameter changes
DELAY, (Pre-delay)
When the DELAY button is pressed the display in the EFFECTS section shows the current PRE-
DELAY value. This value can be adjusted using the LEVEL slider in the EFFECTS section.
DELAY inserts a tiny space between the source sound, (a key being pressed), and the resulting
reverb output. Adjusting the PRE-DELAY value will change the length of this space. The purpose
of pre-delay is to “clean-up” the resulting reverberated sound so that the original sounds can
be heard to speak clearly for a fraction of a second before the reverb effect kicks in.
PRO-EFX SECTION
Unlike the REVERB section, the two available parameters in the PRO-EFX section do not have
definitive names. They are named simply PARAM 1 and PARAM 2. Whenever you select a new
PRO EFX effect using the Virtual-POT, the functions of PARAM 1 and PARAM 2 will change
accordingly. This allows for maximum flexibility of the effects in this section without the need
for too many buttons.
For example, when you use an effect that contains movement or “modulation”, (such as a
CHORUS, or PHASER effect), it is very important to have a control for the speed of that movement,
(usually called the MODULATION FREQUENCY). However, certain effects contain no modulation,
(such as COMPRESSOR or LOUDNESS), so a dedicated speed control would have no function
when these particular effects were selected.
Whenever you select a new REVERB or PRO EFX effect using the Virtual-
POT in either section, the two user controllable parameters related to that
effect will be reset to the factory pre-set values.
For example, let’s say you select FLANGER in the PRO EFX section and
then change the values of both PARAM 1 and PARAM 2. Now you temporarily
switch to a different effect, for example TREMOLO and then return to
FLANGER. The values of PARAM1 and PARAM2 will not be those which you
set earlier but the factory pre-set values. This ensures that each effect will
sound “correct’ when first selected.
The effect sections themselves do not have memories for storing these
parameter changes. If you have modified the parameters of an effect in
either section and wish to memorize these changes, you must store the
entire resulting sound combination into one of the PERFORMANCE MEMORIES.
Below is a list of PARAM 1 and PARAM 2 functions in the case of each effect.
