Synth Glossary

Control input:
An input into part of the synthesizer that allows that bit to be modulated by another part of the synth. For example there is a control input in the amplifier which controls the level of amplification. If a very slow sine wave (an LFO) is patched into this input then the sound will slowly get louder and quieter. If an LFO was patched into the control input of the oscillator instead, then the sound would go higher and lower in pitch....

SH-09
The SH-09 (or Synthesizer-09) is a single VCO monophonic analog synthesizer with a 2 1/2 octave, 32-note (F-C) keyboard. The VCO is switchable between 5 octaves: 2', 4', 8', 16', 32'. Available waveforms are sawtooth, square, pulse (with pulse width modulation), or white noise. There is also a sub-oscillator switchable between a square wave one octave down, a square wave two octaves down, and a pulse wave three octaves down. It is possible select the noise source at your oscillator and still have the sub-oscillator as a waveform. The VCF is self oscillating and can be modulated by the envelope follower which is wired to the external input. The envelope generator is an ADSR (attack decay sustain release) with a slider for each stage. On the control panel to the left of the keyboard is a horizontal pitch-bend/modulation lever, with pressure up and down controlling modulation amount. There are also two sliders controlling amount of modulation routed to the VCO and VCF, as well as a slider adjusting portamento amount and the main power switch. On the back panel there is a main output, and the CV/gate inputs and outputs.
