TheReFmB1rth v0.1.0-beta.2

TheReFmB1rth v0.1.0-beta.2 — corrective FM-1 beta

This prerelease contains the corrective hardware architecture produced after the first physical FM-1 test exposed disconnected Felucca/ReFm control paths, plus the browser/readback and runtime-diagnostic work added since beta.1.

Built from commit 2b4c537cc1a1f8c42c43ee953e14e27d7740837b only after that exact commit passed host DSP/integration tests, the browser/WASM build, JieLi FM-1 target compile/link, target memory budgets, package manifest/checksum verification and the target sample link-size experiment.

Physical workflow

• dedicated 240×240 ReFm pages: HOME / ACID / STEP / DRUM / MIXER / FX / SONG / PROJECT
• physical keyboard routed directly to the selected ACID A / ACID B engine
• physical PLAY starts/stops the ReFm sequencer instead of Felucca's old audible sequencer
• fresh Pattern A contains an audible factory demonstration for immediate PLAY testing
• 16-step ACID editing with NOTE / REST / TIE, Accent, Slide and probability
• 808/909 lane editing with OFF / HIT / ACCENT
• mixer level/pan/delay/reverb plus mute/solo and master FX editing
• four project save/load slots using Felucca's CRC-checked storage
• held-note panic on editor-page/machine transitions
• target-only idle ACID fast path to reduce wasted DSP work

Browser/editor additions

• device-to-browser live state synchronization
• START / CONTINUE / STOP through the firmware MIDI realtime path
• full A–H ReFm project backup and restore using the versioned project codec, project CRC and chunked SysEx transport
• restore changes live RAM only; persistence still requires the normal FM-1 project SAVE action
• one-click read-only runtime diagnostic capture for CPU, DMA lateness and user/supervisor stack headroom
• downloadable runtime JSON compatible with tools/target_runtime_report.py

Physical beta gates shown in the browser

• zero DMA deadline misses
• sustained audio CPU <= 75%
• peak render <= 82% of one DMA-half deadline
• user-stack free headroom >= 4096 bytes
• supervisor/ISR-stack free headroom >= 1024 bytes

Status

This remains software-gated beta firmware, not hardware-proven stable firmware. The next required step is the second physical FM-1 pass covering LCD/control behavior, live keys, Pattern A, sustained stress diagnostics, USB/TRS MIDI, USB audio, project persistence and rollback/recovery.

Keep the verified official V15/recovery path available while testing. No custom firmware has a zero-brick guarantee.

TheReFmB1rth v0.1.0-beta.1

TheReFmB1rth v0.1.0-beta.1 — first beta candidate

This is the first beta candidate produced after the initial physical FM-1 test exposed the control/UI integration problems in the earlier hardware-test build.

Built from commit 3b881e3f845a71f7fdf280b2f0b5016d84b3a254 only after the exact commit passed host DSP/integration tests, WASM build, JieLi FM-1 target build, target memory budgets, package manifest/checksum verification and the target sample link-size experiment.

Hardware workflow in this beta

• dedicated 240×240 ReFm pages: HOME / ACID / STEP / DRUM / MIXER / FX / SONG / PROJECT
• physical keyboard routed directly to the selected ACID A / ACID B engine
• physical PLAY starts/stops the ReFm sequencer rather than Felucca's old sequencer
• fresh Pattern A contains a small audible factory demonstration so PLAY is immediately testable
• simple four-knob page mappings shown directly on the LCD
• 16-step ACID editing with NOTE / REST / TIE, Accent, Slide and probability
• 808/909 lane editing with OFF / HIT / ACCENT
• mixer level/pan/delay/reverb editing plus mute/solo
• master drive/delay/reverb/filter editing
• four project save/load slots using Felucca's CRC-checked A/B storage
• held-note panic when changing into editor pages or switching machine
• target-only idle ACID fast path to reduce wasted CPU while voices are silent
• browser installer/editor and browser-safe firmware channel

Beta status

This build is software-gated beta firmware, not yet hardware-proven stable firmware. It still requires the second physical FM-1 validation pass: sustained audio/CPU/late-buffer measurements, UI/keys/transport, USB + TRS MIDI, USB audio, project save/load and rollback/recovery.

Keep the known-good V15/recovery path available while testing.

TheReFmB1rth hardware-test-0.1.3

TheReFmB1rth hardware-test-0.1.3

Experimental FM-1 hardware-test firmware. Keep a known-good recovery path available before flashing.

Included

• ACID A + ACID B 303-style engines
• SAW / SQUARE, cutoff, resonance, Env Mod, decay and accent
• per-ACID distortion
• 16-step sequencing with NOTE / REST / TIE, Accent and Slide
• 808 + 909-inspired drum engines
• A-H pattern bank and song sequencing
• mixer, delay and reverb sends
• MIDI control and live web-editor integration
• compact 240x240 FM-1 UI work in progress
• browser installer support for this release asset

Hardware-test status

This remains an experimental hardware build. Do not treat it as a stable release until physical FM-1 CPU/underrun, UI, MIDI, persistence and recovery tests have passed.
