DigiHedra 0.1 (pre-release)

A beta (pre-release). It runs on a Digitone mk1, its author's, where it loads and works as expected, and was checked in digikit's emulator on OS 1.43 and 1.44.

A Hedra-style three-voice rhythmic pitch shifter for the Digitone mk1's audio inputs: three voices from -2 to +2 octaves, chromatic or in a key and scale (Major, Minor, Melodic Minor, Harmonic Minor, Double Harmonic, Lydian and Minor Pentatonic) from the note a pitch detector hears, with microtune, glide and pitch correction, each behind its own time division of a delay in time with the Digitone's tempo, in the Hedra's four delay modes (pitch feedback, series, dual with cross feedback, dual), rhythm patterns, half speed, swell, freeze, eight presets and the Hedra's MIDI CCs. DIGIHEDRA in core-dn1's Mod Menu (hold a track key) opens its page; while it is open it owns the audio engine (the synths are muted) and processes the inputs, and NO gives both back. Needs core-dn1 3.2.

It is not affiliated with the maker of the Meris Hedra and uses none of its code. The README has the pages, the keys, the MIDI chart and how it works.

Install

DigiHedra needs core-dn1 3.2 or newer and elekloader from its main branch (or elekloader's web page): its buffers are in the Digitone profile's bulk area, which the 0.4.0 app does not know.

OS	files
1.43	core-dn1-3.2.elemod, digihedra-0.1.elemod
1.44	core-dn1-3.2-os1.44.elemod, digihedra-0.1-os1.44.elemod

python -m elekloader.patch --stock Digitone_and_Digitone_Keys_OS1.44.syx \
    --mod core-dn1-3.2-os1.44.elemod --mod digihedra-0.1-os1.44.elemod \
    --out Digitone_OS1.44-digihedra.syx --version HE01

With several effects mods in one build (the other pedals, DigiCosm, DigiChroma), use core-dn1 4.0 in 3.2's place: it has the RAM for them. Flash the .syx with Elektron Transfer; the stock OS file always restores the unit.

Files

The two DigiHedra files are built from this repository's main at 76deb88: byte for byte the files tested on the unit, and the same as mods/digihedra-dn1 in irpina/elekloader#96. The core files are the ones in elekloader's core-dn1-v3.2 pre-release.
