How to update the Infinite Digits EZEPTOCORE
Download the EZEPTOCORE .uf2 file: overclocking firmware if you clock the module externally, non-overclocking if you use the internal clock; low-latency builds respond faster but leave less headroom for effects. If you need to remove the module to reach its rear button, switch off and unplug the case first. Connect the module to your computer with a USB data cable. Hold the small button on the back, press the front-panel RESET button, then release the rear button. A drive named RPI-RP2 appears on the computer. Copy the .uf2 file onto it. The drive disconnects when the module accepts the firmware and restarts.
Just for reference. For complete and up-to-date instructions, always refer to the manufacturer's official firmware page.

Release notesopens in a new tab — github.comVersion 8.0.5 — 3 Oct 2026
- Replace stretched companion playback with live granular Time Stretch, capped at 16×. The triggered effect applies an 8× minimum while active.
- Correct granular reverse playback, slice resets, stop/loop boundaries, and transition fades.
- Stop generating or requiring companion audio in the sample-manager, web exporter, and Rack source. Existing companion files are preserved and ignored.
- Speed up sample-manager batch rendering with up to four workers, while preserving import order, shared caches, cancellation, and transactional saves. A 13-file local benchmark improved from 12.1 to 5.9 seconds with identical output hashes.
- Fix Rack storage test portability on Windows and improve tooltips.
Install v8.0.5 firmware before using primary-only exports from the updated sample-manager or web-tool source. Existing cards work without regeneration.

Version 7.3.0 — 23 Jun 2026
### What's new
- zeptocore: Added realtime stretch control for zeptocore playback. Hold B and turn Knob Z to move from bypass into increasing stretch amounts.
- zeptocore: Added a Retrigger volume ramps toggle using buttons 13 + 14 + 15 + 16. It is enabled by default and lets retriggers ramp volume back in instead of always staying flat.
- EZEPTOCORE/ectocore: Added realtime stretch behavior random-effect/rune workflows when the selected rune is timestretch-only.
### What's changed
- Updated MIDI CC 20 to control realtime stretch instead of bass volume.
- Updated Zeptocore filter handling so the filter control behaves as a low-pass cutoff when the DJ filter mode is disabled.
- Clarified the quickstart and combo docs for volume, tempo, sample selection, random jump, random effects, random tunnel, quantize, and realtime stretch controls.
