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 Solus is a 2 VCO, monophonic analog synthesizer with a 3-octave, 37-note (C-C) keyboard. It, like most ARP synths, features mostly sliders instead of knobs. It was built into a flight-case, with all of its inputs and outputs on the inside of the case lid.

Both VCO's feature a slider selecting variable waveforms from sawtooth to pulse, as well as a slider controlling pulse-width and the amount of pulse-width modulation. VCO2 is syncable to VCO1 and can be detuned. The pulse-width can be modulated by the LFO or the ADSR. The VCF (four-pole, lowpass filter) has controls for frequency, resonance, as well as three sliders controlling modulation amount from the keyboard, the LFO, and the ADSR. It also features a digital ring-modulator and a pitch-bend knob. The back panel features interfaces (in and out) for CV, Gate, and Trig. Also in the back is a footpedal input and External Audio input, as well as high and low outputs.
