Roland SH-2 (1979)
Monophonic analog synthesizer with two detunable oscillators and sub-oscillator, -24 dB/octave low-pass VCF with external processing, LFO for PW/VCO/VCF/VCA modulation and ADSR envelope.
Synthesis
Oscillators
- VCO1: range: 32'/16'/8'/4'/2', waveform: sine, saw, square, pulse with PWM; bender on/off switch
- VCO1 sub-oscillator: square wave
- VCO2: range: 32'/16'/8'/4'/2', waveform: noise, saw, square, pulse with PWM; fine tune, tune range switch (wide/narrow)
- PWM mode: manual, envelope, LFO
Filter (VCF)
- Resonant/self-oscillating -24 dB/octave low-pass
- Controlled by LFO, keyboard tracking and envelope (reversible polarity)
