Description
A tribute to the Buchla 266 Source of Uncertainty — three noise colours (flat, low-biased, high-biased), a Fluctuating Random Voltage that glides continuously between new targets, and a Quantized Random Voltage that jumps to a new value on each trigger — sharing the card with an antialiased wavefolder (ported from Chris Johnson's Utility Pair) and a Pulse In 1 alternator that duplicates each incoming pulse across Pulse Out 1 and Pulse Out 2 in turn. Z switch Up turns Main/X/Y into bipolar attenuverters for the wavefolder's CV In 1, FRV's output, and QRV's output respectively, with pot-pickup so returning to normal never snaps a value to wherever the knob was left.
