A slice gets a note name only when at least 60 % of up to twelve reads
across its body sit on one note; growls, pitch drops and noise get no name
rather than a wrong one. An optional song key spells names with flats in
flat keys (Eb2, not D#2).
Producers found the tracked plugins jumpy: the shared tracker switched notes
after 10 ms and retuned every 5 ms, so growls and formant basses flickered
and every tracked plugin acted on wrong notes.
Shared tracker (common-dsp):
- A new note needs a steady read for 40 ms; an octave down 80 ms, an octave
up 200 ms (an octave-up read still fits the note's period and counts as
agreeing). Inside a note the tuning only moves past a 0.25 semitone
deadband. Follow bends keeps the old fast behaviour as an option.
- A trust score turns the note unsure while reads disagree; Tracker::active
and NoteState report it, and Fallback latches "step back" across note ends.
- Notes end when the window start stays below the gate's release level for
20 ms, so short gaps between notes are seen without waiting for the gate.
- PitchSource replaces the old (midi, gate, glide) arguments: Audio, MIDI or
Note mode (a set note, no detection), plus a key lock (minor, major, root
only) that snaps reads to the key.
- stems.rs: synthetic stems (growls, wobble, reese, formant, 808 slide,
layered drop, noise riser) and a score; examples/tracker_report scores the
corpus or real WAV stems. On the corpus the old behaviour makes up to 28
extra note starts per second; the stable default makes none.
Plugins:
- Anvil, Lathe, Temper, Knurl, Planish, Braze and Forge gain the NOTE pitch
source, the key lock and Follow bends (shared common-params crate and a
shared header switch in common-ui).
- Unsure tracking: Anvil brings the original sub back in place of the sine,
Lathe passes the audio through, Knurl fades its texture out; Temper,
Planish and Braze hold their last sure tuning. Readouts show the note only
when it is sure.
- Anvil gains Mode: Replace or Enhance (keeps the original sub and adds the
sine under it).
- Planish slides its band edges over 6 ms on a new note instead of snapping.
- Ballast defaults to Grid parts, which need no tracking.
KWeighting is one channel of the standard's pre-filter and RLB high-pass,
computed from the analog prototypes so every sample rate is exact. lufs()
turns a mean square summed over channels into LUFS. A full-scale 997 Hz sine
reads -3.01 LUFS within 0.03 LU from 44.1 to 192 kHz.
SvfCoef::allpass has the phase of a Linkwitz-Riley split at the same
frequency, so a crossover tree can keep its lower bands in phase with
the upper ones. The test checks it against a real LR4 split sample by
sample and for flat magnitude.
Lathe places EQ bands on harmonics 1-32 of the played note, so a cut on
harmonic 3 stays on harmonic 3 on every note. Temper normalises each
note's level before an oversampled shaper and tunes its floor, push and
bright filters to the note, so every note distorts the same.
The note tracker moves from Anvil into common-dsp, together with a
state-variable filter, 4x oversampler and harmonic meter. Anvil's
behaviour and editor render are unchanged.
docs/ideas.md collects all plugin ideas and their status.
Two new CLAP effects aimed at riddim and dubstep production, plus shared
crates so all four plugins keep one look and reuse DSP.
Anvil 0.1.0 (io.storyboard.sub-anchor):
- Replaces the band below Split with a clean mono sine. Every note gets
the same peak level and restarts at the same phase, so switch-ups keep
their weight and kick hits line up.
- Pitch and note starts come from the audio (YIN, 80 ms lookahead
reported to the host) or from MIDI notes sent to the effect.
- Dynamics, Drive, Octave, Glide, Phase, Gate and Keep; Solo sub monitor,
note readout, level meters and a low-band oscilloscope.
Crucible 0.1.0 (io.storyboard.resampler):
- Records its input continuously in a lock-free ring with host transport
markers. Capture takes the newest 1-16 complete bars on the bar grid,
following tempo changes, or the newest audio when stopped.
- Grid (straight and triplet) or transient slicing, manual cuts, slice
audition without audio-thread allocation.
- Export writes the loop, trimmed, declicked and normalised slices named
and tagged with their root note, and an optional 2048-sample wavetable
for Serum and Vital.
Shared:
- common-ui holds the palette, fonts, knobs and panels taken from Patina;
Patina renders identically. Rotary knobs at their minimum no longer
tessellate a zero-length arc into NaN vertices.
- common-dsp holds biquads, a Linkwitz-Riley crossover, YIN, note helpers
and a float WAV writer with sampler root and Serum frame chunks.
- Catalog, CI matrix, release tags, editor previews and docs cover both
plugins; a script test keeps the catalog and workflows in step.
