Third-Party Notices

This project stands on excellent prior work by the Fractal Audio community. This file states exactly what came from where and under which license.

mcp-midi-control (TheAndrewStaker)

The primary foundation of this project's protocol layer.

This repository also contains the `fractal-midi` package — a
codec-only TypeScript library that builds and parses Fractal Audio
SysEx wire bytes without depending on a MIDI transport. The same

This project neither claims endorsement from, nor affiliation with,
Fractal Audio Systems or Ashun Sound Machines. It is a software
utility that communicates with hardware the user already owns via
publicly-documented SysEx, NRPN, and CC messages — including, for
Fractal devices, the protocol information Fractal Audio itself
publishes in its "MIDI for Third-Party Devices" specifications.

The package name `fractal-midi` uses the "Fractal" trademark
descriptively (nominative fair use) to identify the hardware the
library targets. The package does not claim official status and

This product also includes gen-3 (Axe-Fx III / FM3 / FM9) protocol
data derived from:

    Copyright 2026 Andrew Mercurio ("BoodieTraps")
    https://github.com/drewmerc302/fractal-syx-codec
    The gen-3 preset-file format spec (FORMAT.md) and the read-ordinal
    effect-type roster tables. The Huffman/CRC codec here is a clean-
    room reimplementation from that spec; the roster name tables are
    derived from its data, independently cross-validated against our
    own hardware captures.

Additional development-only dependencies (TypeScript, tsx, jest,
etc.) are not redistributed in Object form and are listed in
package.json.

Pass-through credits carried by the content above and used here:

forgefx-midi (sKuhLight)

Source of the FM9 modifier model used by fm9/protocol.py and fm9/device.py: modifier slot addressing (slot N = effect id 3 + N - 1, 32 slots), the field map (pid 0 source, pid 1/2 min/max, pid 8 target effect id, pid 9 target param id, curve fields), and the FM3 modulation source enum used as the starting hypothesis for the FM9's. Re-implemented in Python; no code copied verbatim.

ForgeFX (sKuhLight)

Consulted for the bindModifier call sequence (bind target effect, target param, then source) and the modifier address-model architecture. No code copied.

Fractal Audio Systems

The officially documented command set (scene select, block bypass and channel, preset/scene name queries, tempo, tuner, looper, status dump, and the effect ID table) comes from Fractal Audio's public specification "Axe-Fx III MIDI for Third-Party Devices", Revision 1.4, applied to the FM9 with its model byte 0x12.

Amplifier Library Guide

config/amp_models.json is generated from that guide. For each FM9 amp-roster ordinal it records factual specifications only: the real-world amplifier modeled, the original cab, DynaCab pairing, front-panel controls, tube complement, and tonestack position.

The guide's prose notes and tips are the author's own writing, and some of them quote other people. They are deliberately not reproduced here. The generator can extract them with --with-prose for local use, to config/amp_models.full.json, which is gitignored.

Amplifier specifications in that guide derive from manufacturer manuals and websites.

Yek's Guide to the Fractal Audio Drive Models

config/drive_models.json is generated from that guide's own section headings (" (based on )"): factual model-to-pedal identity only. The guide's prose synopses and tips are not reproduced. FM9 drive models added after the guide's last update remain unmapped by design.

Fractal Audio Wiki (community wiki), effect-type pages

Fractal Audio Wiki (community wiki)

config/cab_models.json records, for 2,235 of the FM9's 2,237 stock cab slots and for all 45 firmware DynaCabs, the cabinet each was captured from, and where the source gives them the manufacturer, size and microphone.

Facts only. Each model value is the cabinet's identity - make, model, speaker complement - reduced to its first clause. The wiki's surrounding commentary and its quotations from named individuals are deliberately not reproduced; the generator's --with-prose mode keeps them in a gitignored local file instead.
