DigiChain is a web app made to make the creation of sample chains as easy as possible for use on the Digitakt / Digitakt II (and any other sampler that can slice-up samples).
Create drum kits for the OP-1 Field / OP-Z / OP-XY / Octatrack.
Import OP-1 Field / OP-Z / Octatrack / M8 chains and convert between formats.
Combine and convert chains between spaced / sliced all from the list.
Automatic creation of .ot slice data files when exporting as 44.1k 16/24 bit.
Embeds cue markers for M8 slicer.

OT Exports
OP-1 Field Kits
v1.5.0
- Show loading overlay until async sample processing has completed to prevent multiple calls to renderList before the list is ready.
- Style tweaks to support rendering within itch.io windows.
- Enhanced waveform rendering accuracy and performance (thanks to boourns · GitHub for the pull request).
- Dither exports option when outputting 8/16/24 bit wav or 16 bit aif files.
- Added user feedback on sample load processing.
- Improved responsiveness of list with large numbers of samples loaded.
- Reduced file processing load times.
- Added a welcome screen with some usage guidance, tips, and link out to documentation page.
- Show the length in seconds of the sample being edited on the editor.
- Support importing samples and slices from Renoise Instrument files (.xrni) in addition to sample data from Renoise Project files (.xrnx).
- Mini-waveform renderer no longer builds waveform cache when skip render is enabled.
- Prevent default event bubbling on keydown events for handled keyboard shortcuts, stops ‘funk’ noise on macOS for valid shortcuts.
- Improved creation of OP-1 Field / OP-Z chains, nudging end to zero crossing per slice if one is present in the last 256 samples.
- OP-1 Field / OP-Z exports now default to one-shot play mode.
- Shift + click on Pad With Zero selected action allows entering a custom value to pad the sample(s) with in seconds.
- Config option, treat slice data in files as distinct files on join - defaults to YES, when set to YES, if a file contains slice data or has had slice data configured those slices will be represented as distinct files when creating new chains that include those selected slices; when set to NO, the per-file slices will be discarded when joined to new chains.
- Moved about pop-up into unified audio config, settings, about panel.
- Supporting the import and export of digichain session files.
- Using a custom dialog instead of the browser built-ins to handle user prompts/confirmations.
- Moved browser based alert messaging into a toast style notification that displays at the top center of the active window or dialog.
- OP Export UI for creating drum kits for OP-1 Field and OP-XY via a drag and drop key layout.
- OP Export supports combining samples on Left / Right / Center to more easily create A/B kits for use on the Field.
- Chains / Spaced Chains buttons now do not both display, they are toggled via the new Chain Type toggle icon.
- Rendering created chains to the top of the list instead of out to a downloaded zip file (the Shift + Click button action), is now toggled from an icon.
- XY preset rendering toggle icon, when enabled, chains are created as XY Preset folders in the output zip, max 24 slices and samples longer than 20 seconds will be automatically truncated.
- Invert phase selected action.
- Flip L/R selected action, switched the left and right channels around.
- Editor waveform height adjustment control (height retained as setting).
- Crop keyboard shortcuts in the editor, Shift+Click to crop to a new sample, staying in the current sample; Shift+Ctrl+Click to crop to a new sample and open that new sample in the editor.
- Bug fixes:
- Delayed list rendering bug when removing all selected samples.
- When a waveform is too short to render a valid mini-waveform, the renderer replaced the parent dom node, causing a dom tree layout issue, this is now fixed.
- Sanitize name selected action.
- When restore last used audio config is set to off, the text label of the audio config indicator was blank.
- Where canvas element replacement threw an error when slicing to samples from the slice panel with skip render waveforms enabled.
- Toggling the max-seconds per chain option de-selected all samples.
- XY common configuration no longer sets the seconds time limit per chain to on.
- OP Export renders at the target sample rate for XY presets and 44.1kHz regardless of the target sample rate for OP-1 Field kits.
- Play-head was not displayed when playing the highlighted sample in the list using the P key keyboard shortcut.
- Only positive buffer values were being removed in the condense action.
- Edit panel not consistently closing when using the Escape key.
- Smoothing on fuzz selected action caused peak spikes on some sample material.
- Setting DT / DT II / XY / M8 / OT did not toggle the spaced / xy settings and icons when using the common configurations options.
- Slice panel waveform did not show when no slices were set (regression fix from edit panel renderer changes).
v1.4.16
- Nudge Crossings selected action, nudges all zero crossings off from zero.
- Pad with Zero selected action, adds a zero sample to the beginning and end of each file.
- Shift selected action, moves the sample start position over 50%.
- Fixed bug where resampling the list when changing the working sample-rate caused the loop point to bet set on .ot slice metadata.
- Support for reading slice data from the Sonicware LoFi-12 XT custom header data.
- Added common configurations for Sonicware LoFi-12 XT (12/24 kHz target sample rate).
- Added common configurations for Teenage Engineering EP-133 / EP-1320 mono/stereo.
- Fixed some browser specific UI element positioning quirks.
- Added de-serialize from mono L/R back to a stereo sample selected action (halves a mono sample and puts the first half on the left channel, second half on the right).
- Prevent slicing by transient assigning an ot meta loop point flag.
- Added button to set a custom slice count on the slices panel.
- Change default chain names to not contain _ or chars.
- Turn off embed slice data config option by default.
- Use Cue markers as preferred slice data storage within the wav file data.
- Minor wav encode bug, the cue chunk size property should be 8 bytes less than the total chunk byte length, not 4.
- Turn on/off .ot file export options when choosing the ot common configuration on the audio config panel.
- Add OP-XY to common configurations, as this uses wav files as the primary file type.
- Sanitize Names selected action to format file names to align with the guidelines for successful MTP transfer to Teenage Engineering OP-XY filesystem.
v1.4.15
- Amplitude threshold condense selected action, enter an upper and lower amplitude value (between 0 and 1), the sample will be modified to only include amplitudes within the given range, gaps between the audio is removed condensing the sample size.
- Ctrl + Click on Filename column header to sort the list by numeric filename content only.
- Improved drop file order consistency.
- Allow dropping mp3 files.
- If sample has slice information, the slices will be shown on the waveform when the slice panel opens.
- Support multi-touch for selecting/deselecting samples.
