Introducing Sequential_Circuits
American microprocessor based analog synth pioneer, founded by Dave Smith, producing synthesizers and samplers from 1978-1987, when bought by Yamaha (later became Korg R/D). Most families (except rebadged SIEL) share the same CEM based subtractive architecture (Source->VCF->VCA), with differing polyphony and sources (e.g. 1-4 oscillators or a sample). For street prices, see Prepal.

Architectural Classes:
- Additive: Multiple sine wave harmonics are combined.
- Conventional: Single cycle waveforms, subtractive architecture (filtered harmonics).
- FM: Oscillators use Frequency or Phase Modulation.
- Rompler: ROM based samples (often subtractive).
- Sampler: User recorded samples (often subtractive).
- Modelling: Digital model, usually involving a Driver and Modulators.
