Getting started
From the project's README ("Build"):
Needs the m68k cross toolchain, elekloader 0.5+, both stock OS files, and the matching cores (core-4.0-os1.54, core-dn1-4.0-os1.44).
python tools/buildrelease.py
--elekloader <elekloader checkout>
--stock-dt <DigitaktOS1.54.syx>
--stock-dn <DigitoneOS1.44.syx>
--toolchain-bin <m68k-elf bin>The script builds the two 1.3 elemods, lints and patch-checks both, stages them in releases/elemods/, writes local test .syx files under out/, and creates releases/DigiFilter-1.3.zip. Override the cores with --core-dt / --core-dn if they live elsewhere.
Install with elekloader: add your stock OS, the matching core and the elemod, then build the custom .syx and flash it with Elektron Transfer.
Risk and recovery
- Brick risk
- Low
- Requires opening the device
