DEARLY BELOVED. DEARLY DETUNED.

Bless this
mess.

Felucca and Jangada, joined in unholy matrimony.
For richer harmonics, for poorer sleep. Till feedback do us part.

IMMACULATE PERMUTATION 0.2.3 · EXPERIMENTAL
Pixel illustration of Immaculate Permutation: a gold pixel cross glows inside the instrument screen.
Our pixelated aural savior.
No instrument required to admire the heresy.

Original-controls quick start (PDF) · The Book of Sacred Sounds (PDF, 54 pages) · Corresponding firmware source + SDK · Immaculate Permutation hands-on guide · GPL-3.0 license

Begin with Immaculate Permutation, meet Evening Vow, then wander deeper into our sacred sounds. The new hymnbook covers revelation, evolution and gentle LFO blessings; the older quick start remains a companion for the original controls.

THE SAINTS BEHIND THE SOUND

Sing their praises. Sustain the note.

Saint Felucca

Felucca, by Leo Kuroshita (@kurogedelic), Hügelton Instruments and its contributors, is our foundation: engines, sequencing, modulation, USB/MIDI, storage, updater and editor. Their voices carry this congregation.

Saint Jangada

Jangada, by zednaked and its contributors, gave us the drone algorithm adapted for slowly evolving sustain and tension. Patron saint of the note that refuses to leave.

Felucca and Jangada are our code foundations. RND is design inspiration; no RND code or assets were copied. Unaffiliated experimental fork, with gratitude to every contributor. GPL-3.0-only.

Even sermons miss a note.

Brother Sparky has tried his best to craft a sermon fit for your ears. Like all things on this earth, it may be imperfect. Bring curiosity, keep your scriptures safe, and forgive the occasional questionable miracle.

THE LITURGY / READ THE SMALL PRINT

Four stations of the crossfade.

  1. 01

    Present the congregation

    A read-only identity handshake over USB MIDI. It never starts an update.

    No device connected.

  2. 02

    Preserve the scriptures

    Gather your presets, patterns and projects before the rite. Keep official recovery firmware close, should resurrection be required. Stop playback, then download your scriptures here, or preserve them yourself in the Choir Loft.

    Connect your FM-1 to gather a complete backup.

  3. 03

    Choose your testament

    Choose your testament, then connect an FM-1 to receive your sacrament. Selecting an offering begins no rite.

    Preparing the offering…

  4. 04

    Consent is sacred

    Sermons of the UnholyUnion cannot be read by Saint Felucca or Brother Jangada. The holy rite of flashing can fail, including beyond any independent recovery. Drone's blessings do not eliminate brick risk.

    Optional. Permanently erases saved projects, presets, samples and settings after installation.

    The pious or adventurous, may proceed. Once the rite of writing begins, do not unplug or interrupt power. May your fm-1 peal beatitudes of truth and beauty.

THE FREE SERVICE / NO HARDWARE REQUIRED

Receive an unsolicited benediction.

We cannot absolve your GAS. We can validate your decision to own seven delays.

Decorative nonsense only. No audio, permissions, device access or installation.

Blessed are the sequencers, for they shall inherit the loop.
