ENVELOPE MODIFIER
This patch allows the
SH-7
to
be used
for altering
the
envelope
of an external
sound
source.
When
using the
Roland RS-202
Strings or
Roland
VK-6
or
VK-9
Organs, the
gate
output
of these
instru-
ments
can
be
used
to
trigger
the
SH-7
Envelope
Generators, thus
creating
polyphonic
synthesizer-
like
sounds.

This patch allows processing of
an
external
sound
source
by means
of the
Ring Modulator
for
producing
bell-
and
gong-like
sounds.
Good
effects
are
obtained
by
using external sources
with
piano-like
envelopes
such
as
an
electric
piano
or
electric
guitar,
combined
with
the
triangle
wave from VCO-1
(B).
The
sounds
can
be
varied
by
changing the
VCO RANGE
control or
the
VCO
pitch
by means
of the keyboard.
Use
the
HPF.and
VCF
to
remove unwanted harmonics
from
the
sound.
