"The SX-2000 Synthetone is an analog monophonic synthesizer. This type of late 1970's synthesizer design (with the knobs, sliders and switches in front of the keyboard) was also seen in the Roland SH-1000, SH-2000, Minimoog and Elka Soloist. The SX-2000 has 7 presets which include: synthy, harpsichord, flute, clarinet, violin, trumpet and piano. Presets are selected via the red switches towards the left of the keyboard. All the preset sounds can be manipulated.

It features a single VCO, switchable over four octaves and equipped with four waveforms (sawtooth, square, and two rectangular). The VCF is a simple low-pass filter with cut-off and resonance (emphasis) and can be modulated by the LFO or one of 3 preset envelope effects. The VCA can also be modulated by these 3 preset envelope effects which include: repeat (which constantly repeats AD envelope), ASR (with sustain), AD (without sustain). The LFO can modulate the oscillator or the filter with either square or triangle waveforms. Finally a Portamento effect is on-board for those elastic synth sounds."

"Harvestman Piston Honda used as drum machine. 3 channels are clocked by an RCD. The most frequent division is just the Piston into ch 1 of the optomix. The second channel is the piston honda through the first channel of the mod-demix ring mod (Hertz Donut as a modulator) and into the second channel of the optomix, the third channel is the second channel of the mod-demix to the Borg 1 in LPG mode."
