LooLoo
3U Rack Extension · Creative effect · Looper
LooLoo is a two-track audio looper built for looping that moves rather than repeats. Each track records what you feed it, then lets you overdub, reshape and process the loop while it runs — a movable playback window, independent pitch and speed, granular texture, decay, stutter and reverse, all of it on CV. Track B can lock to track A at a musical ratio, so layered loops stay in time by construction.
- Two independent loopers, every knob on CV
- Loop just a slice — then slide it anywhere
- Independent pitch & speed, granular texture
// The device
Front & back
Front panel — track 1 on the left and track 2 on the right in mirror image, each around its own transport wheel, with the shared sync-ratio display in the centre, Bypass top-left and global volume top-right.
Back panel — per-track stereo In, Out, Send and Return with the mix output and through path down the middle, and a full CV block for each track: transport gates, parameter inputs, and record, play, end-of-loop and position outputs.
// Overview
Looping that moves
A LooLoo loop is a starting point you play with, not a fixed phrase on repeat.
Each track is a complete stereo looper with its own audio path, its own settings and its own loop length. Set Bars from 1 to 16, or turn on Free Rec to record any length, press Rec, and the loop closes and starts playing. In Overdub mode Rec layers new passes over the loop; Quant Overdub keeps the punch-ins on the bar, Early Stop ends a take at the next bar line, and Undo steps back one layer at a time.
What sets LooLoo apart is what happens after the loop is recorded. Shrink the playback window to a slice and slide its offset through the recording. Pitch (±24 semitones) and speed (0–2×) are independent — or tie them together with Varispeed for the tape-machine feel — and grain size sets the texture of every change. Decay turns overdubbing from an endless build-up into a self-erasing echo, the stutter engine captures and repeats a slice for fills and glitches, and reverse flips the loop with a smooth turnaround.
Each track has its own FX send and return, so any Reason effect can sit inside a single track's loop and be folded back in by the Fx amount, with an FX guard to tame feedback-prone chains. Both tracks have their own outputs and are also summed to a mix output.
Every transport action and every continuous control has a CV input, so LooLoo plays as well from a sequencer as from the panel. Each track also sends out a playhead position ramp and an end-of-loop pulse — a loop of any length becomes a clock and a modulation source for the rest of your rack.
LooLoo is the 3U dual-track member of the LooLoo family, between the single-track LooLoo Mini and the 5U LooLoo X-Caliber.
// Detail
What's inside
Two tracks
- Two independent stereo looper tracks — separate audio paths, settings and loop lengths
- Per-track stereo output plus a summed stereo mix output
- Sync Lock: track B follows track A at 0.25, 0.5, 1, 1.5, 2, 2.5 or 3× its length
Recording
- Loop length 1–16 bars, or free length with Free Rec
- Play and Overdub modes; Quant Overdub and Early Stop
- Undo of the last overdub pass; Clear; Reset retriggers from the loop start
Playback shape
- Window size and offset, 0–100 %, wrapping around the loop end
- Pitch −24 to +24 semitones, independent of speed
- Speed 0–2×, with optional tape-style varispeed
- Granular grain size 10–300 ms; smooth musical reverse
Decay, FX & stutter
- Overdub decay 0–100 %, from infinite build-up to a self-erasing echo
- Loop fade 0–2 s to soften starts and stops
- Per-track stereo FX send/return with Fx amount, plus an FX guard
- Momentary stutter with slice size and speed
CV
- Per track: 6 transport gates (record, play, clear, undo, stutter, reset) and 13 parameter inputs
- Global volume input
- Per-track outputs: position ramp, end-of-loop pulse, record gate and play gate
