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....

Pro-One
The Pro-One is a monophonic, two oscillator synthesizer with a 3 octave, 37-note (C-C), keyboard. VCO1 is switchable between sawtooth and pulse waveforms (either or both) and can be synced to VCO2. VCO2 is switchable between sawtooth, triangle, or pulse waveforms (any or all) and has a switch to disable keyboard control. The LFO can output a sawtooth, triangle or a pulse waveform. The Pro-One has a single envelope generator (ADSR). The VCF has controls for frequency cutoff, resonance, envelope modulation amount, and keyboard follow amount. The VCA is controlled by the ADSR. The available modulation sources are Filter Envelope, VCO2, or LFO. These sources can modulate VCO1 frequency, VCO1 pulse width, VCO2 frequency, VCO2 pulse width, or the filter. The Pro-One has a 40-note dual sequencer with a volatile memory (the sequence is lost when you turn the instrument off) and an arpeggiator.
