A
monophonic analog
synthesizer with a 32-note
keyboard. Manufactured between
1980 and
1982.
The SH-09 offers a single
VCO with a 5
octave range (2'-32') and a ±65 cent
tuning range. It is
switchable between
sawtooth,
square and
pulse (with
PWM)
waveforms, along with a
white noise source. A square/pulse sub-
oscillator is also available.
As a
filter there is a self-oscillating low-pass
VCF which can modulate an external
source through the
envelope follower. There are controls for
cutoff,
resonance, envelope
polarity, envelope control and MOD control.
The
LFO offers
sine, square and
random waveforms, as well as controls for
rate and
delay. There is also a
sample/hold section and a CV/gate
interface for external
triggering.
The SH-09 has often been compared to the
SH-101, but due to the 09's
discreet circuitry and the 101 using the
CEM 3440 chip, the two
units sound very different from eachother.
