Synth Glossary

Many synths can only play one note at a time (they are monophonic). With the arpeggiator on, if more than one note is pressed at a time, the synth will alternate between the notes. They also often have a range control that allows the user to tell the ynth to play additional octaves - so if the range is set to two octaves the synth will play the keys that are held down in the octave that they are played and then in the next octave up/down....


Very early VCS3 (pre-Putney), note Oscillator 1 The original portable synthesizer introduced in 1969 had a solid Aformosia cabinet which housed the following modules interconnected by means of a matrix patchboard.

3 x Voltage Controlled Oscillators.
Noise Generator.
2 x Input Amplifiers.
Ring Modulator.
Voltage Controlled Low Pass Filter.
Trapezoid Envelope Generator.
Voltage Controlled Reverberation.
2 x Stereo Output Amplifiers.

The VCS3 had:3 Voltage Controlled Oscillators, a Noise Generator, 2 Input Amplifiers, 1 Ring Modulator,1 Voltage Controlled Low Pass Filter,1 Trapezoid Envelope Generator, a Voltage Controlled Reverberation unit, 2 Stereo Output Amplifiers and a Joystick. Routing the various functions of the instrument was done via a small pin patchboard.
