Beat Repeat: interrupt a phrase with purpose

Choose the interruption before the effect

Picture a drum pattern that briefly gets stuck, then resumes normally. That is a clearer intention than adding random stutter everywhere. Beat Repeat captures a slice at scheduled boundaries and replays it on a tempo-related grid. Unlike an ordinary delay, it can replace the ongoing phrase while a repeat plays. The first example uses original synthesized drums; the second uses an original harmonic pluck, not sampled performances.

Four timing controls, four different jobs

Interval decides how often a fresh capture starts. Grid sets the slice length and repeat spacing. Offset moves the capture boundary in sixteenth notes. Gate specifies how long repeats are allowed after that boundary, also in sixteenth notes. The Gate knob here is a time window, not a level threshold like the separate Gate audio effect.

The drum example starts with Interval 1 Bar, Grid 1/16, Offset 0/16 and Gate 4/16. Chance is 100%, Insert mode is selected, and Repeat is off. Listen for a short recurring interruption followed by ordinary playback. The source must first provide a slice to capture: the beginning is not an instant infinite echo. Let the example run through several hits before deciding whether a setting has done anything.

Rehearse one repeat, not a cloud of accidents

Change Grid to 1/8 while keeping Interval at 1 Bar. The longer slice contains more of the hit and repeats less frequently; 1/16 focuses on a shorter fragment. Return to 1/16, then increase Gate from 4/16 to 8/16. More of the phrase is now eligible for interruption. Undo that extension if the original pattern loses its identity instead of gaining a fill.

Move Offset from 0/16 to 4/16. This changes what gets captured and when the interruption happens, rather than merely delaying the finished output. A tiny slice from a quiet part of an uploaded recording may produce an unimpressive repeat. Choose a capture point containing an audible event before increasing Volume. Offsets should make sense within the selected Interval; wildly mismatched values are not a useful starting point.

• Mix adds repeats to the original signal. Listen for a level increase or clutter when the two coincide.
• Insert suppresses the dry signal while a repeat plays and passes it otherwise. Use it to create a clear interruption.
• Gate outputs repeats only. Gaps can therefore be silent; do not mistake that intentional mode for a broken effect.

Make the response fall away

The pluck example uses Grid 1/8, Gate 8/16 and Mix mode. Pitch starts at −5 semitones, Pitch Decay adds downward movement of 2 semitones per successive repeat, and Decay is 30%. Listen for the repeated fragment separating from the original as a falling response. Set Pitch Decay to 0 to hear a fixed-pitch version, then set Pitch to 0 if you want the source pitch back.

Pitch here is varispeed: transposition changes how the slice is read, not an independently time-preserved pitch shift. Decay multiplies each successive repeat by a smaller level; compare 30% with 0% to hear why an unchanging repeat can dominate. Volume is the repeat level, not a master output fader. Lower it from 70% to 40% when Mix mode buries the next original note.

The enabled filter is a band-pass centred at 1.6 kHz. Turn it off before deciding whether a quiet repeat needs more Volume. Its Width value currently acts as filter Q: increasing it narrows the audible passband, despite what the name might suggest. Try 0.7 versus 2 and keep the lower value if the repeat becomes too thin. Trust that listening comparison over an assumed octave-width interpretation.

Once placement works, reduce Chance to 50% for fewer eligible repeats. This implementation makes deterministic decisions per interval and slice; it is not a promise of a fresh random fill on every playback. There is no Variation randomizer. The Repeat button forces continuous stuttering while active; click it off before judging the scheduled pattern again. Keep the version that creates a useful contrast, and remove the effect when the uninterrupted phrase communicates better.
