A
duophonic analog synthesizer with a 44-note
keyboard. Manufactured between
1978 and
1981.
The SH-7 features 2
VCOs, switchable between
sawtooth,
triangle,
square, and
pulse waveforms. VCO2 is
detuneable from VCO1, which has an extra square wave section (VCO1B). A
noise generator is also available, as well as a
ring modulator with external input. The
oscillators can be
modulated manually, by the
LFO or by one of the 2
ADSR envelope generators. A
monophonic mode is featured for creating thick 2-VCO sounds.
For a
filter, the SH-7 offers a self-oscillating 24
dB/octave low-/high-pass
VCF. It has modulation controls for
ENV1, LFO /
sample/hold, keyboard /
pedal and VCO / noise.
The
VCA features a
hold function and can be modulated by either one of the EGs. The LFO offers sine, up-ramp and pulse waveforms and has controls for
delay and
rate. A
sample/hold section is also present, with 3 waveform
sources and
output lag control.
Other features include a
bender with flexible modulation
routings (pitch/
cutoff/VCA by
CV/LFO), plus a
mixer section for VCO1, VCO2, VCO1B, noise and ring modulator / external signal. A CV/gate
interface is included for external control.
