Looper
| Looper | Key | Result |
|---|---|---|
| Empty | LOOP | Start recording |
| Empty | hold PLAY, press LOOP | Start a quantized recording (needs MIDI clock, otherwise LOOP blinks red 3 times) |
| Recording | LOOP | Stop now, or for a quantized recording at the end of the current bar, then play |
| Loop exists | PLAY | Play / pause |
| Loop exists | LOOP | Erase now |
| Loop exists, playing | hold PLAY, press LOOP | Erase at the end of the loop (LOOP blinks red until then; paused, it erases now) |
| Erase waiting for the end | LOOP / PLAY | LOOP erases now; PLAY takes the erase back, the loop plays on |
| Any | SHIFT + LOOP | Tap tempo (see Tempo); never records, stops or erases |
| Any, while a scene morphs | SHIFT + PLAY | Stops the morph where it is (see Morphing to a scene); doesn’t play or pause |
- Quantized: recording starts on the press, which counts as bar 1 (4/4). Ending it records to the end of the bar in progress, so the loop is always a whole number of bars. It closes immediately if the clock stops.
- Erasing uses the gestures that record: LOOP at once, PLAY + LOOP quantized, here to the loop’s own end, so it needs no clock. For half a second after LOOP stopped a recording, LOOP doesn’t erase, so a double press can’t lose the new loop.
- Length: up to 2:45. The loop lives in RAM and is gone at power-off. There’s no overdub.
Transport knob (the big purple one), once a loop exists:
| Control | Function |
|---|---|
| Turn while playing | Speed in 5ths and octaves, 2× down to 1/16×, then reverse back up to −2× (4 detents per step) |
| Turn while paused | Scrub |
| Press | Back to 1× forward |
| SHIFT + turn | Nothing |
| SHIFT + press | Writes a bug report |
LEDs: LOOP is red while recording and blinks while a quantized recording finishes its bar or an erase waits for the loop’s end, at the slow blink everything waiting uses (a picked scene slot, the CHOMPI key ready to confirm); a refusal is 3 quick blinks. While a loop plays, PLAY and LOOP crossfade in white to show the position (dimmed when paused). The transport LEDs show speed and direction while it plays, the scrub speed in white while it’s paused, and nothing without a loop.
