Sample Snap and Crossfade for Elektron Digitakt

Snap native SRC start, end and loop markers to nearby zero crossings. In the normal recording editor, apply an adjustable loop crossfade with one-level undo.

Module version 0.2.2. Base firmware: 1.53 / 1.54.

About this module

Snap native SRC start, end and loop markers to nearby zero crossings. In the normal recording editor, apply an adjustable loop crossfade with one-level undo.

• Seek the previous/next zero crossing for start.
• Seek a crossing for the actual end, STRT + LEN.
• Seek a crossing for the loop return point.

How to use it

1. Load a sample on an ONESHOT track and open SRC. Press SRC again if you want the native waveform view.
2. Release held trigs and TRK. Hold FUNC and turn STRT, LEN or LOOP: left seeks an earlier crossing, right a later crossing. Ordinary turns still work normally.
3. For a crossfade, make a normal recording and finish it to reach the trim editor. Choose a region, then hold FUNC and turn F to set a short crossfade.
4. Press FUNC + UP to apply. Audition with the native recorder controls; FUNC + DOWN undoes the edit. Press YES for the normal trim/save workflow.

Controls

SRC: FUNC + E — STRT

Seek the previous/next zero crossing for start.

SRC: FUNC + F — LEN

Seek a crossing for the actual end, STRT + LEN.

SRC: FUNC + G — LOOP

Seek a crossing for the loop return point.

Recorder: FUNC + E

Turn automatic marker snapping off/on.

Recorder: FUNC + A/C

Seek a crossing for the start/end marker.

Recorder: FUNC + F

Set loop crossfade length from 0 to 200 ms.

Recorder: FUNC + UP / DOWN

Apply the crossfade / undo it.

Recorder: YES

Use the native trim/save workflow.

Compatibility notes

• SRC snapping works on ONESHOT and RAM-P1. RAM-P1 does not gain a file-backed waveform page.
• Exact snapped offsets last for the session; normal quantized parameter values are saved.
• No per-step exact snap locks or control-all snap operation. Search is bounded to 4,096 nearby samples.
• Crossfades shorten the selected loop by the overlap length. Only the last crossfade can be undone.
• Loaded samples and RAM takes have no panel entry into the crossfade editor in 0.2.1. The tutorial uses the normal recorder.
• SRC retains its two-page toggle; FUNC + YES remains Save Ptn on SRC.
• Conflicts with DIGISLICER, which owns the same SRC key hook.

Test evidence

Runs on Core 2.1. Emulator regressions on OS 1.53 and 1.54, an emulator CPU-load comparison with stock, and Modwerk source-build parity with the native build are in TESTING.md. sumedho reports this Core 2.1 build fully tested and working on a Digitakt 1, OS 1.53 and 1.54, for about one to two hours including project save/reload and a power cycle (2026-10-14).
