A mash-up of features and structure of several Yamaha CS-series synths with a GUI design based on the CS-80.

The defining element of most of the CS-series was their dual-synthline architectures, with two complete and independent/interdependent VCO/VCF/VCA chains.

This mash-up of CS-15, CS-30 (and some CS-80), features two LFOs plus step LFO.

Thanks to 'bluesmoke' and 'cakebox' for figuring out the IL/AL envelopes.

No claim is made that this sounds like any CS synth; only borrows from their concepts and controls.


32-bit, so will require jBridge, etc., (or a DAW that will bridge) for use on 64-bit systems.

The link on the website is to a Sync.com folder that also contains the .osm Synthmaker source 'schematic', 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.

Made with SynthMaker
