KX77FREE has launched Kx-PolyM-CSE, a vintage modular polyphonic synthesizer instrument for Windows.

This one is a special work to implement a CS70M emulation and the x16 sequencer inside a modular VA. Even if the CS70 used for the tests is broken (some voices and keys are HS, no split, …), I could work nicely and really check this piece of synthesizer story. I really appreciated to go to the past… I added some “CS” offsets to the initial values of my usual setting, created the waveforms, modified the Lfo, etc, to match with the original synthesizer. Of course, you can use this plug-in like you want with or without the “CS” offsets.

I love the vintage japanese synthesizers because generally they have more creative parameters.

The particularity of this CS is its two channels (for each: 1 VCO, 1 VCF, 1 VCA) which provide nice stereo pads. And its Vcos are not Dcos (like those of 80’s synths), so the detune between the two Vcos and each voice creates rich chorus fx to build nice organs or string ensembles. But the great features of this vintage synthesizer are: the Lfo which generates a frequency modulation up to 500 hz controlled by the AD envelope and the Sine oscillators of the Vcas which create a solid base of the sounds using Bp or Hp filters.

The Kx-PolyM-CSE for Windows (VST) is a free download.
