MIXER
These slide levers function to mix the four
Solo Melody sound sources: 16' and 8' square
waves including pulse width modulation (uni.
8' sawtooth wave | / V ), and polyensemble.
The Polyensemble
control allows the output
sound
of
the
Polyensemble
Section
to be
processed by the Solo Melody Section. İf you
don't want the Polyensemble Section Envelope
Generator
to affect this processing, set the

LFO (Low Frequency Oscillator)
PULSE WIDTH MODULATION
The pulse width modulation can be controlled
(1) manually; (2) by the envelope generator;
and (3) by the LFO (low frequency oscillator).
(1) Manual

Set the Modulation Selector Switch to ENV.
Instead of manual operation of the slide levers,
the envelope curve generated by the envelope
generator functions to control the sound.

ENVELOPE GENERATOR
This envelope generator functions in the same
manner
as in the Polyensemble and Bəss Sec-
tions. The envelope curve generated here is also
used
for adjusting pulse width
modulation,
VCF, and VCA modulation.
