README
Bibesque
Bibesque is a Workshop Computer adaptation of the Bib stereo dub processor by Plinky Synth. It recreates Bib-inspired drive, wavefold, stereo tape delay, clock quantisation, rhythmic multi-tap delay, modulated reverb, shimmer and dub freeze using the Workshop's three pots, switch, CV inputs and six LEDs.
Install
Flash uf2/Bibesque_1.0.0_rc1.uf2 to a Workshop Computer program card, then
reset the module. This is a hardware-tested release candidate.

Controls
Main selects Drive, Delay, Reverb or Mix in four regions. LEDs 0–1 show that page as binary: off/off, on/off, off/on, on/on.
- Drive: X = drive; Y = bipolar delay send. Clockwise Y is normal stereo delay; anticlockwise is asymmetric ping-pong. Tap Z to toggle overdrive and wavefold.
- Delay: X = delay time; Y = feedback. Tap Z once to begin a multi-tap phrase, then tap up to eight relative repeat heads. Move X substantially to clear the phrase and return to one even repeat. Pulse In 1 clock-quantises X to Bib-style 3/4, straight and dotted divisions across octaves.
- Reverb: X = reverb send; Y = decay. With Z Up, X sets persistent shimmer.
- Mix: X = wet/dry mix; Y = output level. Hold Z Down for dub freeze.
With Z Up on the Delay page, X controls tape speed (stop through 2x) and Y controls wobble. Long delays and long multi-tap phrases use automatic tape slowdown, extending the 32k-sample tape to roughly two seconds.
CV In 1 and CV In 2 are bipolar modulation inputs for the active page's X and Y parameters. CV is added after physical-pot pickup.
LEDs
LEDs 2–5 change with the active page. LEDs 2 and 3 show effective X/Y values, including CV. LEDs 4–5 show relevant state: wavefold/ping-pong, clock-lock/ multi-tap count, shimmer/wet mix, or freeze/limiter reduction.
