Synth Glossary

Analog Synthesis:
This term is normally used to refer to the tradional synthesis model used by analog synthesizers in the 1970s. It is also known as subtractive synthesis. It involves oscillators, the outputs of which are mixed together and fed into a filter (where certain frequencies are subtracted) after which they are fed through an amplifier. The amplifier and filter are normally also driven by envelope generators....


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.
