Stage 18 · FM-1_901 · Native JieLi build

Änderungen seit 1.1

Entwicklung seit analogBEAST 1.1

MUSIC DISK / MD16

Das MUSIC DISK-System ist eine zentrale Erweiterung von analogBEAST 2.0.

• 292 KiB NOR-Flash-Bereich: 0x97000 bis 0xDFFFF.
• Eigenes MD16-Dateisystem mit variablen Datensatzlängen.
• Pattern-IDs bis 512 im aktuellen Speicherpfad.
• Dateiobjekte für Patterns, Songs und Alben.
• Weitere definierte Datentypen für Presets, VL-1 und Musicbox/M1.
• CRC32-Prüfsummen, Sequenznummern und Commit-Marker.
• Schutz gegen unvollständige Schreibvorgänge.
• Kompakter RAM-Index für schnelle Pattern-Auswahl.
• Logische Löschung über Tombstone-Datensätze.
• Geschützte Speicheroperationen außerhalb des Audio-Interrupts.
• Kein automatisches Formatieren oder Überschreiben fremder Datenträger.
• Keine automatische Neuinitialisierung des Datenträgers nach Firmware-Updates.

MD12 und MD13 waren frühere Entwicklungsstufen mit alternativen Transaktions- und Speicherverfahren. MD16 ist das neuere Dateisystem.

Wichtig: Garbage Collection ist im Dateisystem implementiert, im Stage-18-Gerätepfad jedoch deaktiviert. Die Datenfunktionen benötigen weitere Hardware- und Stromausfalltests.

Sequencer und Arranger

• Erweiterte Pattern- und Step-Datenmodelle.
• Song- und Album-Datenstrukturen.
• MIDI-Import- und Musicbox-Werkzeuge.
• Bearbeitung und persistente Speicherung von Pattern-Daten.
• Wiedergabe-, Transport-, Loop- und Step-Funktionen.
• Schutz vor unsicheren Schreibvorgängen während der Wiedergabe.
• Pattern-Auswahl anhand tatsächlich vorhandener Dateien.

Nicht alle historischen Entwicklungsfunktionen sind automatisch Bestandteil der aktiven, hardwaregetesteten RC1-Bedienoberfläche.

Synthesizer und DSP

• KORG- und BRUTE-Synthesemodi.
• Felucca ANALOG und LOFI.
• Experimentelle B1-Bass-Engine.
• Engine-spezifische Parameterseiten.
• Dynamisch wiederverwendeter DSP-Zustand je Part.
• Fade und Ressourcenfreigabe beim Engine-Wechsel.

Die B1-Engine ist noch keine originalgetreue Donner-B1-Emulation.

Presets

• 32 bestehende beschreibbare User-Instrumente.
• 12 originale Felucca-ANALOG-Werksklänge.
• 5 originale Felucca-LOFI-Werksklänge.
• Gemeinsame Preset-Auswahl mit vorgesehener Engine-Umschaltung.
• P18 SYNTH KEYBOARD und P19 PETZ MOOG als eingebettete Originaldatensätze erhalten.
• Keine Änderung des bestehenden User-Preset-Flash-Layouts.

Die eingebetteten Originale ersetzen kein Backup eventuell bearbeiteter Presets vom tatsächlichen Gerät.

USB und MIDI

• USB-Audio und USB-MIDI als Composite-Gerät.
• Umschaltbare USB-Device-, Audio- und MIDI-Host-Profile.
• MIDI-Routing und zusätzliche Importwerkzeuge.
• Getrennte Regelung von USB-Audio-Ausgang und lokalem MASTER.
• Erhalt des USB8-Original-Composite-Quellstands als Rückfallbasis.

analogBEAST v1.1 — Live Performance & Advanced SONG Arranger

Custom synthesizer / hardware sequencer firmware for the M-VAVE FM-1.

Version 1.1 focuses on live playing, smarter SONG arrangements and editing workflows. It extends v1.0's two synthesis routings (MIKROKORG and BRUTE), 128 pattern slots, 32 SONGs and 4 ALBUMs without replacing the existing SONG/backup storage layout.

New SONG commands

Command	Meaning
OCTAVE	Transpose subsequent song notes by −3 to +3 octaves until changed again
TRANSPOSE	Transpose subsequent song notes by −24 to +24 semitones until changed again
REPEAT	Play the next pattern a total of 1–64 times
JUMP	Set the starting step (1–64) for the next pattern
ENDSTEP	Set the ending step (1–64) for the next pattern
BEGIN	Return to the beginning at SONG END, even if SONG ONCE was selected

Example arrangement:

JUMP     12
ENDSTEP  13
REPEAT    5
A02      64
A03      64
END

This plays steps 12–13 of A02 five times in total, then starts A03 from its normal beginning. BEGIN loops a SONG, not the whole ALBUM; on a BEGIN-induced replay, existing live tempo/preset changes are not automatically undone by reapplying the initial commands.

Live hardware performance

• On the PLAY page, 8 black keys select BANK A–H and 16 white keys select PATTERN 01–16.
• While PATTERN transport runs, a selected pattern is queued for the next pattern boundary, not cut in immediately.
• PRESET can be turned during playback without restarting the transport or replacing the current sequence.
• ALGORITHM adjusts tempo outside the HOME page too.
• OCT− / OCT+ shift live sequence pitch one octave at a time; STOP clears live pitch offsets and a pending NEXT.
• Keyboard LEDs reflect playing notes (including pitch changes) rather than marking bank/pattern selections.
• SONG/ALBUM modes keep their existing end-of-song queued navigation.

Web editor and MIDI transfer

• Piano roll: quick TRANSPOSE −1/+1 and OCTAVE −12/+12 actions, undo support, bounded note values, corrected TIE presentation.
• Python transfer CLI updated for SONG command IDs 13–18.
• The 4-byte-per-row SONG model and 13,648-byte v5 payload remain unchanged. Existing v1.0 SONG rows and SysEx operations remain compatible; no automatic rewrite of v1.0 arrangements.
• SONG/ALBUM transfer supports write → readback → backup → restore, with a write lock when transport is running.

Verification

• Firmware builds successfully within code and RAM constraints.
• QA2 UI simulator: 19/19 passed.
• QA3 arranger interpreter: 90 checks passed; device boundary/STOP simulator: 10/10 passed; NOR A/B storage/CRC/rollback tests passed.
• QA4 SysEx CLI ↔ real C firmware-dispatcher simulator: 225 checks passed.
• Hardware: the project maintainer reports successful operation of v1.1 on a real FM-1 (23 October 2026).
• The older Golana UI regression suite still has outdated expectations; it has not been fully adapted. Host simulation does not replace exhaustive hardware and cross-platform USB-MIDI testing.

Download and compatibility

• analogBEAST-v1.1.fwsc — the byte-identical, hardware-tested v1.1 developer firmware package, renamed for distribution.
• SHA256SUMS-v1.1.txt — SHA-256 for the published package.
• Source archives generated by GitHub.

The firmware retains FM-1_901 and the Felucca Update loader identity. Do not use build.sh --release 1.1 for this package: the upstream release build changes the identity and is not the tested package. The internal menu version label in the hardware-tested binary may still display v1.0; the functional code and release package are v1.1.

Back up presets, patterns, SONGs, ALBUMs and device settings before updating. The published website/WebAssembly emulator may still reflect the prior build until separately redeployed; the firmware package in this release is the authoritative v1.1 download.

analogBEAST v1.0 — First Public Release

Custom synthesizer and full-song sequencer firmware for M-VAVE FM-1.

analogBEAST brings two distinct synthesis signal paths, a characterful digital Steiner-Parker-inspired filter, 128 pattern slots and hardware SONG/ALBUM playback to the FM-1 — accompanied by a graphical Web Studio, WebAssembly emulator and browser-based USB installer.

Synthesis — two different routings

MIKROKORG: virtual-analog-inspired dual-oscillator structure with oscillator sync, ring modulation, envelope/LFO modulation, filter choices and effects.

BRUTE: a different oscillator path with SAW/ULTRASAW, PULSE/PWM, METAL-style wavefolding, SUB/overtone components, Brute Factor internal feedback, and a digital Steiner-Parker-inspired two-pole filter with selectable LP/BP/HP responses and nonlinear saturation.

The two routings are implemented inside the same GOLANA engine. The Steiner-Parker filter is digitally inspired by the original concept; it is not a circuit-accurate clone.

Sequencer and performance

• 128 patterns in 8 banks (A–H), 16 patterns per bank.
• Banks A–D: up to 64 steps per pattern.
• Banks E–H: up to 16 steps per pattern.
• Note, velocity, gate, swing, timing and step flags/type editing.
• SONG MODE: 32 songs, up to 64 rows/commands each; PATTERN, TEMPO, PRESET, REST, ARP and END; once/repeat playback.
• ALBUM MODE: 4 albums, up to 32 song entries each; ordered playback of saved songs.
• 32 sound programs P01–P32, selectable with MIDI Program Change.
• USB MIDI and song/pattern transfer tooling.

Web applications

• Project homepage — the entry point for all browser tools.
• Synth Studio — synthesis and ARP editing, P01–P32 program selector, graphical pattern/SONG/ALBUM editor, and MIDI-song import.
• FM-1 Web Emulator — WebAssembly-based simulation, usable without FM-1 hardware.
• USB Web Installer — requires a compatible browser (e.g., Chrome/Edge) with MIDI/SysEx access. Check device detection; back up personal data before flashing.

Release files

• analogBEAST-v1.0.fwsc — installable firmware package, identity FM-1_901.
• analogBEAST-v1.0-webemu.zip — browser emulator distribution.
• Source code archives generated by GitHub.

Compatibility and safety

The firmware deliberately keeps the compatible FM-1 package identity FM-1_901 and the Felucca Update loader identity. Back up all user programs, patterns, songs and projects before installing or updating. This is independent custom firmware, provided without warranty.
