Cymbols (synth)

Cymbols is a percussion synthesizer specifically designed for electronic cymbal and hihat sounds. The methods it uses to synthesize sounds are derived mostly from old analog drum machines (with a few tweaks), though it is not designed to specifically emulate any one machine or series of machines.

Shapeulator (synth)

Shapeulator is essentially the product of a modular patching session, and a desire to have the core setup used available for further sound design fun. At the most basic level, it is a subtractive synthesizer, with some additional features that make it especially useful for certain types of pads, fx sounds, and synthetic percussion.

Spectral Lemuring (effect)

Spectral Lemuring is, as the name implies, a spectral processing effect which is inspired by a discontinued freeware plugin with a similar name. The feature set isn’t exactly the same, but like the plugin that inspired it, it can process the high-magnitude and low-magnitude parts of the FFT signal separately, and can also “freeze” the signal.

Put simply, it’s a lo-fi pitch shifter with some extra functionality.

FourHead (effect)

FourHead is not really a delay or granulator, though it lives in that realm. It is based on an audio buffer which constantly records the input in chunks. This buffer is then read by four “play heads” which play it back as looped segments.

FourHead was developed for the 2021 KVR Developer Challenge.

Spectral Destroyer (effect)
