MUTABLE DREAMS 1.2 — VOICE COLOUR AND RESPONSIVE LANDSCAPES
Private development, 27 October 2026. Published 1.0 and 1.1 unchanged.

SOUND CHARACTER
All fifteen voice paths have been reviewed and adjusted. Kick: gentler pitch
transient; Snare: softer body/noise balance; Hat: remove the fixed resonant
bandpass peak and use its two-stage envelope. FM: stronger midrange articulation
following touch and envelope. VA: wider pulses in the lower Tone range.
Harmonic: less emphasis on high partials. Rings: damped, filtered mallet.
Elements: softer excitation and brightness. Choir: a gentle second harmonic.
Bass: Shape now changes its octave body; Harmonics retains the sub blend.
Mellow: more defined rounded harmonics. Satin and Spectral: distinct interpolated
waveform colours and slow motion. Velvet Keys: a soft transient settling into
the body. Breath: a reed with odd harmonics and low-pass noise.

Original Choir, Bass, Mellow, Velvet Keys and Breath have 25 ms control smoothing
for continuous Tone/Shape changes. Discrete chord types and FM ratios retain
their intended selection behavior. Finite extra partials fade out before
Nyquist during high notes and bends instead of being cut abruptly.
No new saturation on the master, no blanket EQ, no new oversampling buffer.
All tracks remain freely assignable. Model count is still 15, not 15 new models.

LIBRARY
Relative to the immediately preceding organic-refinement checkpoint:
224 of 288 tone recipes and 60 of 93 Biome records were adjusted. IDs and names
are unchanged. There are 92 musical Biomes plus Blank. This is a curation pass,
not an increase in library size. Earlier 1.2 already added 64 tones and 16 Biomes.
Reload a factory Biome with PRESET to get the revised recipe. Saved custom
parameters are preserved; their sound can change with the revised engine.

RINGS PERFORMANCE FIX
Six moving Rings voices with dense rhythm, grains, delay/room and animated edits
hit the overload guard in the first hardware pass. The old optimized path only
handled a stationary pickup. A changing pickup used the slower per-sample loop.
The new ramped block path retains every mode, gain ramp, sample rate and summation
order. 4096 reference/optimized blocks, with 1/7/31/64/97 samples and 8..64 modes,
are byte-identical on the native compiler. The device re-test is recorded in
device-tests.json; do not confuse it with first-pass/device-tests.json.

GRAPHICS
Brighter Nunito/Barlow text, offline 4x rasterization for every role, 4-bit glyph
coverage, unchanged font metrics. The physical screen remains 240 x 240 pixels.
Luminous rims and accents sit behind legible controls; no blur/framebuffer added.
The living field now follows the current page's parameters. Examples:
LIVE: Density changes population, Space/Density growth, Colour light, Motion flow.
GRAIN: return changes population, size grows forms, feedback lights the rim.
CLOUD: noise and return change population; freeze reduces the field's motion.
RHYTHM/SEQUENCE: occupied hits/steps change density; length/probability shape size.
FILTER: cutoff changes growth; resonance changes light; Breathe changes motion.
SPACE: return changes population, room tail growth, feedback light.
MODULATION: Marbles/Tides/Warps drive density, depth and light.
Utility pages intentionally stay sparse. Values approach their target gently.
These are illustrations of settings, not a waveform or a CPU/audio meter.
Grain-page markers also follow mix, size, position and reverse. No extra timer.
Native curves remain cached; circle drawing rejects pixels outside the active
40-row tile. Motion Off remains pixel-static. Held-key help remains legible.
The browser editor receives matching page-coloured, parameter-responsive light.

COMPARISONS AND SCOPE
Voice-Lab contains 15 dry isolated engine pairs (identical patches/notes/velocities)
and four complete Biome pairs (engine AND recipes may change), from exact firmware
DSP offline. 44.1 kHz, 24-bit stereo WAV; per-pair RMS matching, not LUFS; no external
mastering. Manual playback only. Numeric tests are not a subjective listening
verdict. Low settings may sound deliberately subtle; not every patch is transformed.

Patch v7, MIDI protocol, User Bank layouts and the full granular tape are unchanged.
The original snapshot, failure logs, reference tests, backup and installation
receipts are retained alongside this document. This checkpoint is not a release.
