beat-repeatstutterglitchclockedlo-fi

A clock-synced beat-repeater with two power-on modes sharing one 2.33-second circular buffer. Glitch mode loops ratcheted sub-slices of the last beat with optional reverse, decimation and bitcrush; Stutter mode slices the beat and shuffles or repeats slices in real time. Pulse In 1 sets beat length, CV In 1 freezes recording while playback continues, and Audio Out 2 stays dry for parallel routing.

Controls

Main knob

Zone / Probability
Selects the ratchet zone (Glitch — 1, 2, 3, 4, 6) or slice zone (Stutter — 1, 2, 3, 4, 8), with position within the zone setting reverse probability (Glitch) or drift probability (Stutter)

X knob

Degrade / Shuffle
Glitch mode sets the degradation amount (decimation then bitcrush); Stutter mode sets the shuffle probability

Y knob

Degrade Probability / Repeat
Glitch mode sets the degradation probability; Stutter mode sets the repeat probability before a slice advances

Switch

Probabilistic: Effect triggers randomly against the probability threshold. Held at power-on (or left unheld) this also selects Glitch mode.

External Gate: Effect triggers while Pulse In 2 is high. Held at power-on this also selects Glitch mode.

Force: Effect applies to every slice. Held at power-on this selects Stutter mode instead of Glitch mode.

Inputs & Outputs

Inputs

Audio 1

Main Audio Input
Source audio for buffering and processing

CV 1

Freeze CV
Above approximately 0V stops recording and loops frozen buffer content

CV 2

Mod CV
Bipolar modulation added to performance knobs — Glitch mode adds to X and Y, Stutter mode adds to X only

Pulse 1

Clock Input
Rising edge defines beat length (max 2.33 seconds)

Pulse 2

External Gate
Gate control for switch-middle trigger behaviour in both modes

Outputs

Audio 1

Processed Output
Glitched/stuttered output, or pass-through when the effect is inactive

Audio 2

Dry Output
Always a dry pass-through of Audio In 1

CV 1

Activity Gate
High while glitch/shuffle is active, low during pass-through

CV 2

Descending Ramp
Falls across each slice and resets at the slice boundary

Pulse 1

Slice Clock
Pulse at each ratchet/slice boundary

Pulse 2

Clock Mirror
Direct mirror of Pulse In 1

README

Glitch records into a shared 2.33-second circular buffer and runs in one of two modes, chosen at power-on by the switch position.

Choosing a mode. Hold the switch in the desired position while the card powers on or resets: Middle or Up (or not held) loads Glitch mode; Down loads Stutter mode. A boot animation confirms the mode — Glitch flashes LEDs 0, 2, 4 in sequence three times; Stutter flashes LEDs 5, 3, 1 in reverse three times. Once the mode has latched (about 100 ms after power-on) the switch reverts to its live performance role in both modes.

Glitch mode. On each clock pulse the beat length is measured and a ratcheted sub-slice of that beat is replayed, optionally reversed and degraded with sample-rate reduction then bitcrushing. Main selects the ratchet zone (1, 2, 3, 4, 6) and the reverse probability within that zone; X sets the degradation amount and Y the degradation probability. CV In 2 adds bipolar modulation to both X and Y. When not glitching, live audio passes through unaffected.

Stutter mode. A live breakbeat slicer. Main selects the slice zone (1, 2, 3, 4, 8) and the drift probability within that zone; X sets the shuffle probability and Y the repeat probability, which governs how often a slice repeats before advancing. CV In 2 adds bipolar modulation to X only.

Shared behaviour. In both modes the switch selects how the effect is triggered: Up is probabilistic, Middle is gated from Pulse In 2, and Down forces the effect on every slice. CV In 1 above roughly 0 V freezes recording so the buffer contents loop while playback continues. Audio Out 2 is always a dry pass-through of Audio In 1, allowing parallel wet/dry routing.
