Chorg DS-600

A simplified FM instrument - based on the basic idea of the pretty obscure Korg DS-8, which was built around the voice of the Yamaha FB-01 4-op FM module. In place of the then-bewildering Ratio Tuning and Modulation Index way of producing waveforms, it had a set of pre-formed FM waves that one could shape 'up' from sine - a bit like the way the Casio CZ instruments worked but with FM instead of Phase Distortion. It also had only two algorithms - a pair of Modulator/Carriers (like DX100 algo 5) and a 4-op stack.

With this vst, I've pushed it to a more conventional Ratio-tuned FM instrument and expanded it to six operators; also two algos - three 2-op pairs or a 4-op stack (X-Mod) plus one 2-op pair. I've retained much of DS-8's more conventional analog synth nomenclature and the Coarse/Fine tuning of the operator pairs (Oscillators). Also given it a second LFO.

A much friendlier way to FM, but less limited than DS-8.

Built with Synthmaker, so the actual sound does not match that of the DS-8 - but was inspired by major elements of it's architecture.

The link on the website is to a Dropbox folder that also contains the .osm Synthmaker source 'schematics', so anyone with SM, or it's successor Flowstone, can alter it to suit. It's hoped that anyone who makes significant improvements will share the result with everyone.

As this was originally built for my own use only, there are no presets included; I wanted to come at the instrument anew each time, as one did with vintage analog hardware.
