Small-ish update, desktop standalone will be released from this version for beta testing towards the end of September – this will be distributed via Gumroad and itch.io, macOS will come first followed shortly by the Windows 11 build.

We have some basic Tonverk support in this release, using the multi-sampler format to hold the sample chains, I have set the default grid lengths in the common configurations to max out at 84 slices, as this uses only the 7 standard octave options without needing to dip into the Transposition to get to the first slice. I have a strong feeling the elmuti format will get expanded for what it is able to support over from the sfz open format and I’m noodling on a focused tool just for this, at least for my own use – this may or may not be made public at some point depending on how far along I get it.

List of changes:

• Added support for importing slice data from Ableton Simpler (supporting transient detected slices or manual slices depending on what was active when the .adv preset was saved).
• Additional changes toward desktop app support.
• New setting for Octatrack exports, “Use even numbered slices as loop point of prev slice on .ot exports?”; When this is set to YES, and the .ot file creation is set to YES, joined files are treated as pairs, with the first being the start (attack) part of the slice, and the second being the Octatrack (loop) part of the slice.
• Clear slice data selected action so all slice data can be cleared at once if needed.
• Cut/Paste action button on sample editor panel.
• Show sample play head on sample editor panel.
• FireFox support warning in header bar.
• When creating spaced chains, a new setting in the settings panel allows the pad to be set to repeat the last sample in the chain (the default setting), pad with silent slices, pad with a random slice from the current chain, or pad with reversed version of the samples in the chain starting from slice 1.
• Fixed position of header toolbar on settings panel; Fixed position of x close icon on all dialogs.
• Fixed custom chain names having double file extension, removed slice count append from custom chain names.
• Add Tonverk common configurations in audio settings panel.
• Added support for generating basic .elmulti Tonverk multi-sampler presets to act as slice chains.
• Fixes bug where turning seconds per file on, did not turn off spaced chain mode resulting in no chain download button being shown to the user.
• Changed the default naming convention for chain names to be shorter text and correctly pad the chain number when creating many chains at once.
• New option in the settings to use the date epoch at time of creation number instead of the name of the first sample in the chain.

Thanks to all those who submitted feature requests and bug reports, got a lot of long standing bugs squashed in this one!

The main URL has been updated with quite a lot of new features and bugfixes – lots in here such as session import/export, much improved waveform rendering both visual accuracy and time to render, OP-X kit builder, OP-XY drumkit preset generation (turn your existing chains into XY compatible presets).

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).

• Added basic error catch in the joinAll method to help surface chain build errors.
• User alert for userAgent version checks to inform users if their browser is of a minimum supported version for the browser API’s used.
• Fixes bug when in the sample editor, and snap to zero was enabled, if no zero crossing could be found on the end point, then browser tab would hang on short samples.
• Fixes bug where an end point selected before the current non-zero start point with snap to zero crossing enabled, would result in a negative preview playback value causing looped playback preview in the editor to not play any audio.
• Defaulting to 48kHz as the working sample rate for broader compatibility with built-in audio devices (continues to be user configurable in Audio Settings Panel, does not change if DigiChain has been used before as this is a restored setting).
• If the sample list is empty, choosing an option from the ‘Common Configurations’ list will set both the Working Sample Rate and the Target Sample Rate to the same value.
• When no samples are selected, clicking the chain buttons showed the processing overlay but did not remove it.
• Selections won’t clear when changing the slice-grid values via the audio config panel (grid choice will still be set to OFF).
• The download buttons will now visually indicate their clickable state.

v1.4.10 is now live on the main url

• .xrns file contents parsing (useful for getting the samples out of a Renoise project file).
• Parse the Renoise song data from within project files and extract slice markers.
• When slicing from OP-1 Field tape.json, prevent the ot slice loop point CSS class being applied.
• Drag-out single file from list (Chrome).
• Option in settings to reverse all even samples in an exported chain (back-to-back mode).
• Snap to zero-crossing toggle option on selections on edit panel.
• Visual zero-crossing indicator on edit panel selection start and end points.
• Surface tempo detection method to the edit panel to detect from the currently selected section of the waveform.
• Fixed regression on .ot file generation not correctly setting the quantize value default to ‘direct’ instead of ‘pattern length’.
• Fixed bug when setting slice-grid options from the audio settings panel.
• Added keyboard shortcuts info pop-up (Shift + ? / Shift + K).

Lots of under the hood changes in this release, the largest two being the move to having the working sample rate independent of the target export sample rate which makes it easier creating chains in stereo 24bit for the Octatrack and then exporting from the same screen to files good for the Digitakt without having to clear out the list to changed from 44.1kHz to 48kHz. And storing the current session data into indexedDb browser storage.
