ZAPS from Winter Modular and Plankton Electronics is a percussion-line synth voice designed for creating organic sequences that can mutate over time. It uses a combination of different techniques like controlled randomness, morphing, and storing (or locking) of synth-voice parameters in slots that can be externally sequenced.

The module consists of a digitally controlled two triangle-core oscillator FM and AM analog engine with two envelopes and cross-modulation. It comes with a wide range of waveforms (sine, triangle, sawtooth, square, double sine, and White Noise), and two AHR envelopes with continuously variable slopes. Thanks to AM, FM, and XFM cross-modulation, the module is capable of creating rich percussive sounds.

The control is digital, which has many advantages. You can save patches straight on an SD card, deep randomization (independent random of each parameter or entire slots/banks with random sounds), parameter & slot morphing, and more. The module gives you CV control of any parameter and CV out to control external modules.
