MUTABLE DREAMS 1.2 — PRIVATE DEVICE CHECKPOINT, 27 OCTOBER 2026
PRIVATE 1.2 BALANCE BUILD INSTALLED — 26 DEVICE CASES PASSED; OWNER REVIEW READY
Firmware SHA256: 0b93a61c665ca344c7a740811e58985b4927ff66c48b1c233844d81ddc5b4020
Identity: FM-1_710010200

INSTALLATION AND PERSONAL DATA
The old macOS X0X name was a cached label on the actual Mutable Dreams USB device.
Its USB product/location and firmware identity were verified before changing local
CoreMIDI names. No Syntherella device was accessed. The corrected Mutable Dreams
FM-1 endpoint survived the firmware update and restart.
Two identical backups contain all 22 saved objects (project, preferences, sixteen
Biome slots and sixty-four sound slots). The unsaved live patch is separate.
The previous tested private firmware is retained for rollback. Backups exclude
transient granular audio and calibration; no device firmware readback is claimed.
After installation and after testing, all saved objects remain byte-identical.
The original live patch is restored; playback is stopped and remote control released.

EXACT BUILD — MEASURED ON THE FM-1
26 device cases, 31 checks, 641.6 seconds of measured cases.
All fifteen voice paths with six voices, shared effects and animated editing;
six 32-step patterns; fourteen held-button guides including release behavior;
eight warm Biomes; changing grain sizes across 20 and up to 100 with filtered air.
Maximum callback use: 89.04% of the 5.804 ms deadline.
Worst case: Six Harmonic plus grains and full effects with animated editing.
No new xruns, overloads, nonfinite samples, dropped events or USB capture errors
were observed in these cases. Requested full quality may be constrained by the
existing workload admission guard; actual per-case quality is recorded in JSON.
This is measured coverage, not a guarantee for every possible patch or performance.
Normal-Biome UI rates are in VALIDATION.json. The physical screen is 240 x 240.
Static RAM: 72984/98304 bytes.
Audio pool: 334872/344064 bytes.
Flash image: 453716/581564 bytes.

SOUND AND INTERFACE
Rings uses a repeatable damped mallet with a small air component, reducing random
equal-velocity accents without compressing the mix or removing expressive velocity.
Offline: 108 controlled strikes; worst equal-touch energy ratio 1.25849; previous
engine fails the regression. Across 78 Rings tracks, median maximum/median event
peak ratio falls from 1.757 to 1.204. These measurements do not certify subjective
warmth or prove that every owner-reported loud note has the same cause.
The sequence view adds pitch stems, velocity bars and note names. RAM use unchanged.
Offline builds, DSP sanitizers, grain transitions, contextual help, parameter-
responsive graphics, WASM banks and editor/Density tests passed; see VALIDATION.json.

MEDIA AND PUBLIC RELEASES
Private 2:16 update film with calm male English narration and actual firmware views.
Quiet Arrival is the opening music. Terrassentanz/song 5 belongs to Syntherella;
the owner corrected the earlier cross-chat request. Music is native-rendered
current firmware DSP, not a new recording from the FM-1 hardware.
Published 1.0 and 1.1 files, archives, website and uploads are unchanged.

REMAINING BEFORE RELEASE
- Owner listening and usability review, including even Rings accents and warm Biomes.
- Exact-build physical cold start and final visible browser review before publication.
- Complete and record the 1.2 Stock V15 update/return roundtrip before claiming that route for this release.
- Physical TRS-MIDI cable test remains outstanding; USB validation does not replace it.
- Final film/subtitle review, website/release preparation and publishing only after release approval.
