ENV knob: Adjusts

envelope generator source.
OSC B
knob: Adjusts
level

source.
FREQ A
switch: Selects OSC A frequency
destination.
FILTER switch: Selects
filter
cutoff
frequency
destination.
OSC B
(through
POLY-MOD) will be useful for
creating clangorous sounds
such
as
bells, chimes,
percussion, and "ring modulation" effects.
Various
pitch and timbre sweeps can be
obtained, using the filter envelope
generator
to modulate FREQ A.
Note
that the FILTER
switch
is a
redundant path for the the filter
envelope—which
is
already controlled by the
ENVELOPE AMOUNT knob. This path is
provided
so
that
OSC B can
modulate the filter. Therefore the
POLY-MOD FIL
ENV
knob does not
operate through the POLY-MOD FILT switch.
