The primary function of the PRO-GRAM button is Program section, but it may also be used in conjunction with the WRITE button,
to store a new program or permanently edit an existing one.
c) WRITE Button
The WRITE button is used to write new programs and permanently edit existing ones. A Program may be edited in
place or copied into a new location, using the UP and DOWN buttons.
d) UP and DOWN Buttons
The primary function of the UP & DOWN buttons is to select a desired Delay time. An 'autoshift' function causes the
Delay time to change mo re rapidly the longer an UP or DOWN Button Is depressed, so that large changes may be
made quickly.
The UP & DOWN buttons may also be used for program selection and program copying, in conjunction with the
PROG RAM and WRITE buttons.
e) PROGRAM UP and DOWN Footswitch Jacks (Rear Panel - ?)
Two footswitch jacks are provided to allow remote program selection This capability is especially useful for live

3. Regeneration Section

The Regeneration section is used to provide repeating echoes, and to alter the tone colour of flanges, chorusing and
other effects in a variety of ways.
The Regeneration section includes the following:
a) FEEDBACK Control
b) INV Button
c) HIGH & LOW Filters
d) HOLD Button & Footswitch (Rear Panel - ?)
a) FEEDBACK Control
The FEEDBACK control determines how much (if any) of the signal coming out of the delay line is fed back into the
input of the delay line, in order to pro duce a repeating each or add emphasis to a flange. Feedback is also sometimes
called 'Regeneration', 'Recirculation', or 'Resonance' (in a flanger).
b) lNV Button
The INV button in the Regeneration section inverts the phase of the feedback loop when it is lit. It is particularly useful
with flanging, chorusing, etc,
NOTE: only the feedback loop is affected by this switch, and no change will occur if FEEDBACK Is set to O. There
