Apply Scene for Elektron Octatrack

Hold SCENE A or SCENE B and press YES: that scene's locked values become the active Part's own. Hold both and press YES to keep the crossfader's current blend.

Module version 0.1.0-experimental. Base firmware: 1.40C.

About this module

Keep a scene, or keep a blend. SCENE A + YES writes every value scene A locks into the active Part, as if you had turned each knob there yourself; SCENE B + YES does the same for scene B. Hold both scene keys and press YES to write the sound the crossfader plays right now instead. The scenes, the crossfader and the saved Part stay as they were, so the scenes keep morphing from the new base and RELOAD PART takes you back to the last saved Part.

• Covers every scene-lockable page on all eight audio tracks: SRC (the assigned machine), LFO speed and depth, AMP, FX1 and FX2.
• One scene: its locked values, wherever the crossfader is and even when that scene is muted.
• The blend: the value stock's scene morph plays at the current crossfader position, rounded to the nearest knob step; a muted scene counts as not locked, exactly as stock morphs it.
• Nothing new is stored: the result is ordinary Part data that saves, loads and survives a power cycle like a hand-turned knob.
• Pressing it when nothing would change shows NOTHING TO APPLY.

How to use it

1. Lock some parameters in SCENE A and SCENE B. Hold SCENE A (or SCENE B) and press YES to make that scene's values the Part's own: SCENE A APPLIED (or SCENE B APPLIED).
2. To keep an in-between sound, move the crossfader, hold SCENE A and SCENE B, and press YES: SCENE BLEND APPLIED.
3. Save the Part to keep it, or press FUNC + CUE (RELOAD PART) to go back to the last saved Part.

Compatibility notes

• YES with SCENE A, SCENE B or both held no longer shows ARM ALL; YES alone still does.
• The crossfader stays where it is and the scenes keep their locks: a parameter locked in both scenes keeps its sound, while one locked in only one scene can change (after a one-scene apply it plays that lock at every fader position; after the blend stock blends that lock with the new base).
• XVOL and XLV (the crossfader volume locks) have no Part knob and stay scene locks.
• Trig locks and LFO modulation are not written into the Part; the result is the sound on steps without a trig lock.
• With MASTER TRACK on, track 8's SRC and AMP scene locks are not applied: stock has no knob there.
• Not in MIDI mode, and not on MIDI tracks (stock has no scene locks there).
• Undo is stock RELOAD PART, which also discards any other unsaved edits since the last Part save.
• Tested on one MKII over USB on the beta base, by watching values (no audio check); the card build was not run on hardware for this version.

Test evidence

On one MKII over USB on the beta base: SCENE A, SCENE B and the blend apply, NOTHING TO APPLY, Keep, Undo, removal and a power cycle with the module kept (user-reported, values watched, no audio check). Under ot_emu (verify.py, 179 checks): one-scene applies equal that scene's locks and the blend equals stock's morph model at five fader positions, with scene mutes, both key orders and every scene byte locked; the saved Part, scenes and fader stay untouched; RELOAD PART, Part and project save and reload and an emulated power cycle keep it.
