Digitakt II All-in-One

karigardarsson/digitakt-ii-research · ★ 23

Windows tool that builds a custom OS from your own 1.17 file, with 25 Plaits models, DX7 banks and wave zoom.

README from GitHub, MIT

Digitakt II Sample Editing Pack

Four tools for working with samples on Digitakt II:

  • Universal Zoom — zoom in up to 64×, pan across the waveform and reset the view.
  • SmartSlice — find slice points automatically in the SLICE machine.
  • SampleLAB — load or record a sample, chop, trim, audition and save edited copies.
  • CFADE — blend the loop wrap in SLICE playback for smoother loops.

Download the Windows builder · Read the HOW-TO

For Digitakt II with official stock OS 1.17. The builder runs on Windows x64 (tested on Windows 11). You supply your own stock firmware file; no Elektron firmware is included. The application is unsigned, so Windows may display a publisher warning.

Download and install

  1. Download and extract the Windows package, then open DT2-Sample-Editing-Builder.exe.
  2. Select your official Digitakt II OS 1.17 .syx file.
  3. Choose a new output filename, click Build Sample Editing Pack, and wait for the success message.
  4. Back up your projects, Sounds and samples. Install the generated .syx using Elektron Transfer and Elektron's update instructions.

The builder creates a file; it does not connect to or update your instrument. Keep your official stock firmware for recovery. Once installed, start with SampleLAB loading and editing or SmartSlice.

Digitakt II All-in-One

v0.3.0 Community Beta — OS 1.17

Download the Windows builder, matching source and notices · HOW TO: Plaits, Musical WAVE, Déjà Vu, Zoom/Pan · Installation · Recovery · Known issues

25 optimized Plaits model selections and four DX7 banks from Tyler Neely/spacejam, Kári's graphical Plaits UI2.1, Musical WAVE V4/Déjà Vu and One-Shot Zoom V11. Original Elektron animation retained, followed by legal credits.

Supply your own official OS1.17. No Elektron firmware is distributed; the offline Windows builder never connects to or flashes hardware. The complete corresponding source is the explicitly named release asset, not GitHub's automatically generated source archive of this research repository.

Experimental/as-is: recurring Plaits trigger click remains. Earlier Plaits25/DX7 hardware behavior is confirmed; the exact upper-label-fix plus credits image is NOT hardware-tested. No guaranteed support, requested features, maintenance schedule or future OS compatibility. Community contributions welcome. Read the recovery prerequisites before installing.

This All-in-One edition derives from digikit by Em D - https://github.com/ElekLabs/digikit and is supplied under AGPL-3.0-or-later plus DigiKit NOTICE and applicable per-file MIT/runtime licenses. Original Plaits: Emilie Gillet/Mutable Instruments. Earlier releases and this repository's separately authored MIT materials keep their existing licenses. See the release's source/license package; the repository's root MIT file does not replace upstream AGPL obligations.

Current development source checkpoint (not a release update)

Reviewed All-in-One source and validation for candidate bbc534fae45fd4044625edba07c12d4be8b24d8997ccab313e6af0dfccd43626: native Settings > System > Credits/About with no additional boot delay, SY FANG, TWIN/FUSE Repair4/polish, existing Plaits25 graphics, Musical WAVE and Zoom. Exact candidate hardware acceptance remains unverified. No firmware, unfinished CHIMERA/ARP implementation or personal machine paths are included. The downloadable v0.3.0 builder and release assets above remain unchanged.

Earlier Déjà Vu / Zoom editions — v0.1/v0.2 only

The older builder and output hashes below are not the v0.3.0 All-in-One. Use the links above for v0.3.0 (OS1.17 only).

Digitakt II Déjà Vu + ONESHOT Zoom

An unofficial Digitakt II OS 1.17 and OS 1.16 modification that adds two random-loop LFO waveforms:

  • DV-F (WAVE 7): a free-running random loop.
  • DV-T (WAVE 8): a random loop whose read position resets when the track triggers. Retriggering does not erase the stored loop.

DV-F and DV-T are available on all three LFOs. Stock WAVE 0–6 remain on their original firmware paths.

Windows beta

The v0.2.0 Beta release provides a portable Windows x64 builder. It contains no Elektron firmware. You supply the official Digitakt II OS 1.17 or OS 1.16 .syx; the builder detects the exact version by SHA-256 and offers only compatible editions.

Download builder → Select official stock OS → Build → Install via Elektron Transfer

No Python, Git, WSL, terminal, internet connection, or administrator rights are needed. The application never connects to the instrument and never flashes firmware.

Get the required stock OS

The builder accepts these exact official stock files:

  • Recommended: Digitakt_II_OS1.17.syx, SHA-256 26c22f6652625ac2cfd47f7ee970d388ed8b6427dae3563c0a6a2f2d334350d5
  • Supported: Digitakt_II_OS1.16.syx, SHA-256 278541e466edcd77d6b3e018a91fb90185932d3c7de224dd3e68294dddf3a9ec
  1. Open Elektron Support & Downloads — Digitakt II.
  2. Under Updates, download the official Digitakt II OS 1.17 distribution ZIP and extract Digitakt_II_OS1.17.syx.
  3. OS 1.16 remains supported when its exact official file is available.
  4. Before selecting either file, confirm its SHA-256 above. Modified and other-version files are rejected.

Controls

MODE selects a loop length of 2, 4, 8, 16, or 32 steps.

SPH controls the random loop:

  • 0: generate a new random value when each step is visited.
  • 64: lock the stored values and their order.
  • 127: retain the stored values while reordering them.
  • Intermediate values blend probabilistically toward the corresponding endpoint behavior.

Existing SPD, MULT, FADE, DEP, and DEST processing remains on the stock paths.

ONESHOT Zoom

The OS 1.17 combined edition adds real waveform detail to the ONESHOT SRC waveform page. Press encoder C to cycle 1x, 2x, 3.75x, and 1x. Turn C to pan while zoomed. Zoom depends on Déjà Vu's runtime allocation and is therefore not offered as a standalone edition.

Hardware status

The exact OS 1.16 and OS 1.17 V5.1 outputs have both been generated by the Windows builder and tested on a physical Digitakt II. For OS 1.17, initial testing confirmed normal boot, DV-F modulation, DV-T modulation and retrigger, and normal operation with no problems observed. This is initial hardware validation, not exhaustive long-term regression. Across the two tested builds:

  • Normal boot completed.
  • DV-F and DV-T appeared on the LFO pages.
  • Both custom waveforms produced modulation.
  • DV-T repeating and retrigger behavior was observed.
  • Stock LFO waveforms remained functional.

Offline verification also covers exact package identity, six-section decode, HMAC/checksums, stock WAVE 0–6 differential behavior, native ColdFire routing, and Sound-object conversion.

The following areas remain incomplete or limited:

  • Broad MIDI, sequencer, transport, and synchronization regression.
  • Real Sound/Pattern/Project save, reload, and power-cycle persistence.
  • Long-duration stability across a wider set of projects.
  • Compatibility with every setup, project, or future OS version.

Install and recover

Read installation and stock recovery before using the generated firmware. Keep a known-good official stock OS file and a physical MIDI interface available.

Elektron's normal update instructions are available at How to update your device. The startup-menu recovery route is documented at How to update via SysEx transfer.

  • Mutable Instruments — Marbles inspired the Déjà Vu random-loop concept. No Marbles code is included here.
  • Bezronczek — Syntakt Firmware Workbench provided the DV-F/DV-T behavioral reference. Its MIT-licensed implementation informed the behavior; Digitakt II uses its own native ColdFire implementation adapted to the Digitakt II LFO architecture.
  • ElekLabs — digikit (AGPL-3.0) provided reverse-engineering and emulation infrastructure during research and development. For the earlier v0.1/v0.2 editions it is development tooling, not bundled in their Windows application. The v0.3 All-in-One builder DOES include DigiKit native tooling and source, with its AGPL/NOTICE obligations as described above.
  • mischa85 — elektron-firmware-tool provides the MIT-licensed firmware-container handling, compression, and repacking code used by the builder. Its pinned source and license notice are included under windows-builder/vendor/elektron-firmware-tool/.
