FX scenes
A scene holds every effect’s knob values, on both pages, and whether it’s latched. Five dark keys in the middle are scene keys: lower F#, lower G#, lower A#, upper C# and upper D#.
- The first (lower F#) is the blank scene: every effect off and every knob on its default. It’s always there, a one-press way back to no effects. You can’t save over it or delete it, but you can copy it into a slot to start a scene from scratch.
- The other four (lower G#, lower A#, upper C#, upper D#) hold your scenes 1-4. They’re saved to the SD card and come back at power-on.
The lower C# and D# do nothing on the play page.
A saved scene stays as you saved it: changes you make after recalling one are only kept if you save again.
| Control | Function |
|---|---|
| Scene key | Recall the scene at once: every effect’s knobs jump to it, the effects it latched come on and all others are unlatched. FX keys you’re holding stay on |
| Scene key of the active scene | Back to the scene as saved, dropping your changes |
| Scene key of an empty slot | Nothing (the key blinks red) |
| Blank scene key | Every effect off, every knob back on its default |
SHIFT + a scene key changes to it in time with the music instead: a morph, a drop or a crossfade by hand (see Scene changes in time).
What a recall does:
- The knobs land within about 25 ms instead of gliding over 100 ms like a turned knob. Stepped values (freezer length, slicer pattern, delay division …) switch at once. The flanger’s stereo can take up to a tenth of a second: its right channel bends back onto the left one rather than jumping there, which would click.
- An effect a recall turns on starts as if you’d pressed its key: the freezer grabs fresh audio, the shifter swoops, the crusher dives, the flanger’s sweep restarts, the slicer attacks, the tape stops.
- An effect latched in both scenes keeps running without restarting. A freeze held through the drop stays frozen.
- Delay and reverb tails ring out after a scene unlatches them, as they were: a scene changes the settings of a delay or reverb that’s off only when its key next comes on. Turning its knobs meanwhile still moves the tail.
- The input/loop mix, the volumes, the master compressor and the looper aren’t part of a scene. The compressor keeps its settings on the card on its own.
Save, copy and delete
Section titled “Save, copy and delete”Save, copy and delete are on the last three dark keys, no SHIFT needed. They work like TAPE’s and TEMPO’s preset keys, but in the opposite order and their own colours: save first, delete on the outside, in red as a warning.
| Key | Colour | Function |
|---|---|---|
| Upper F# | green | Save the current effect settings into a slot |
| Upper G# | blue | Copy one slot into another, without changing the sound |
| Upper A# (the last dark key) | red | Delete a slot |
- Tap the function’s key. It lights up fully; the scene keys now select slots instead of recalling them. The effects and knobs keep working. The scene keys you can tap light dimly in the function’s colour, the others go dark: every slot but the blank one for save, the saved ones for delete, the saved ones and the blank one for copy’s source.
- Tap the slot. It blinks in the function’s colour. For copy, tap the source first (it stays lit), then the destination. Tapping a picked slot again unpicks it (for copy, the destination first: the source blinks red while one is picked).
- Tap the CHOMPI key, which blinks in the function’s colour once there’s something to confirm. It confirms when you let go; the slot flashes white and the function ends. Holding CHOMPI and using another key or knob is SHIFT as ever and doesn’t confirm, so you can still latch or select an effect or turn a knob coarsely before you save. CHOMPI pressed while you hold an FX key latches it and doesn’t confirm either.
To get out without doing anything, tap the function’s key again. Tapping a different function key switches to that function.
All three speak the same colours: the function’s colour shows what will happen, white that it’s done, red that it was refused (a dark slot tapped) or not stored. In delete, whose own colour is red, a refusal is told apart by its rhythm: 3 quick blinks, where the picked slot and the CHOMPI key blink steadily. The slot flashes red instead of white when there’s no SD card, or the card couldn’t be written: the change works until power-off but isn’t stored. The next save, copy or delete tries the card again, also one you’ve put in since.
Outside a function, the scene keys show the slots: dark when empty, dimly white when saved (the blank one always is), bright for the scene you recalled or saved last, and pulsing once you’ve turned a knob or changed a latch since. The save, copy and delete keys are dimly lit in their colour.
