I made a small contribution to Patch Deck Cards. My patch is on the card pictured above. Each half of the patch is a simplified Quantussy Cell, with only one sample & hold.

Usages

This simple patch yields six (or more) control voltages.

• Two triggers
• Two held samples
• Two (or more) LFO waveforms (depending on the LFOs used)

The triggers can be used for envelope generators, sequencer clocks, etc.

The samples can be used to control VCO pitch, VCF cutoff, etc. Samples are stepped, but can be externally slewed or quantized before applying to a VCO, etc.

The LFO waveforms can be used for any LFO application.

If the LFO waveform being sampled is unipolar (always positive), then the samples will be too. Try using different wave shapes. Use a different wave shape on each LFO.

A Quick Demo

Here’s a video demo, where the triggers are used to pluck resonators and the sampled voltages control the pitch of the resonators.
