SIDOU 1.0.0: shape one sound and keep it

Try it in your browser first: https://dsablic.github.io/sidou/, the cheat sheet and the how-to videos ("Shape a sound in LAB", "Play a .sid" and "What's new in 1.0" are new).

New

• LAB. A view for experimenting on the go: five pages (OSC, ENVELOPE, FILTER, MOD, FX), each with a drawing of what its four knobs do, from the pulse's width to the filter's curve and the effect chain. ENV, LFO and FX on LIVE open it at their page; SELECT turns the pages; ALGORITHM is the page's choice; HOME goes back to LIVE with the sound as edited.
• Keep it in one press. SAVE keeps the sound as one of sixteen USER sounds (KEPT AS U01 LAB 01); EDIT + SAVE names it with the keys. PRESETS on LIVE plays them after the built-ins and DICE. An unsaved edit comes back at power-on.
• Compare, undo, roll. Tap EDIT for A/B; EDIT + LFO undoes (sixteen steps); EDIT + ARP varies the page, EDIT + SCL rolls the whole voice, and neither is ever silent. SAVE + a knob learns any card for MIDI.
• DICE's settings on STEP. Hold EDIT + SCL and turn K1 for the density (SPARSE to FULL) or K3 for the scale (minor pentatonic to chromatic); let go to roll. Saved with the song.
• The ARP helper picks its waveform with PRESETS.
• Readable TABLE and STEP: their small text is at 2×.
• Store health on STATUS, and a background save that failed is retried and reported.

Changed

• ENV, LFO and FX on LIVE open LAB. The chip model is now ALGORITHM on LIVE's TONE page (CC 25 as before); the next effect algorithm is ALGORITHM on LAB's FX page.

Fixed

• Dense .sid players write on time: a block of the audio renders in up to 23 parts instead of 15, so tunes such as Thomkat, Kill Me and The Last Ninja show LATE 0 on STATUS.
• A sound edit no longer asks about the song before SIDS plays a tune, and the sound stays as it was when the tune ends.
• EDIT + SCL on STEP is the same chord whichever finger lands first.

Known untested: long USB audio recordings at 48 kHz (an hour or more) have not been run on a real FM-1; Felucca's resampler may meet a CPU erratum there (felucca-bsp#16). 44.1 kHz is not affected. If a long 48 kHz recording resets the unit or clicks, please open an issue.

The full list is in CHANGELOG.md.

Install

Over USB, at your own risk; the official firmware is one install away. Use Felucca's installer: fm1_install.py sidou-1.0.0.fwsc, from the stock firmware, a Felucca-family firmware or an earlier SIDOU (it finds the FM-1 as "SIDOU FM-1"). Back to stock: install M-VAVE's FM-1.fwsc the same way. Holding OCT- at power-on is a rescue.
