v0.9.3 (2026-06-17)

Fixes

• Scale picker — clicking a scale now selects the one you clicked (it could land a few rows off).
• Sculpt no longer silences Source 2 — with the resonant Blend engaged, your Source 2 layer plays again.
• Converge is now polyphonic — modulating it (e.g. with an envelope) retriggers per note instead of being shared across all notes.
• The Overtone-Scan highlight no longer lingers on a partial when the scanner is off.
• Settings: the Detune label shows a clean “c” instead of a broken character.

New & changed

• Detune range widened (±100¢) and Drive extended for more saturation headroom.
• Source 2 Fine tuning is now a modulation destination (route an LFO/Env for vibrato or sweeps).
• RAND now also exercises Sculpt, Source 2, and the Harmonic Envelope — and leaves Pan where you set it.

v0.9.1 (2026-06-16)

Fixes

• Sculpt waveforms are true now — the Morph shapes account for the engine’s natural harmonic rolloff, so square sounds (and looks) like a square, saw like a saw, triangle like a triangle. Previously a “square” came out as a triangle.
• Resonant noise responds to velocity — it used to play at full level no matter how softly you played, so quiet notes could be drowned in hiss. It now tracks velocity like the partials.
• Morph labels & detents line up — saw / square / triangle / pulse now sit exactly under their positions on the slider and snap to the pure waveform.

v0.9.0 (2026-06-16)

Fixes

• Harmony Wheel on iPhone & iPad — the wheel now tracks what you play (MIDI or the on-screen keys) on mobile. Previously the harmony engine only ran on desktop, so the wheel sat still on phone and tablet.

New

• Sculpt, rebuilt — the bars are an independent multiplier shaped like the sound: a sawtooth reads as a descending ramp, and every harmonic is editable with real headroom to push it louder, not just cut. It no longer mirrors the matrix — Sculpt and the partial matrix are separate tools that stack.
• Mod Matrix — click an existing connection to toggle it off (no more double-click hunting).

v0.8.2 (2026-06-16)

Fixes

• Source 2 off now means off — turning the Source 2 module off used to still leave its “Synth” double quietly doubling your partials. All Source 2 modes now respect the module on/off, so the partials sound clean on their own.

v0.8.1 (2026-06-16)

Fixes

• Stuck note — sliding a note across the on-screen keyboard and lifting (especially in mono mode) could leave it ringing. Fixed at the source: a slide keeps its held-key tracking in sync, so lifting releases cleanly.

v0.8.0 (2026-06-16)

A critical fix-up plus a smarter Sculpt section.

Fixes

• Stuck notes — sliding across the on-screen keyboard and lifting could leave a note ringing. Fixed; slide-and-lift releases cleanly.
• Resonant blend — it was adding broadband hiss regardless of what you played. It now reinforces only the partials you’re actually generating, so a note resonates around itself instead of hissing everywhere.
• Sculpt at “saw” — the far-left morph position is the identity again: Sculpt on at saw is identical to Sculpt off.

New

• Air — a new Sculpt control that widens (breathy) or narrows (focused) the resonant peaks; also a modulation destination.
• The additive↔resonant Blend is now a modulation destination.
• The Sculpt bars show the actual resulting harmonic levels (structure × your multiplier), like the matrix, and you can boost any partial up — not just cut.
• EQ, Delay, and Reverb are color-coded so they read apart at a glance.
• Taller default window (desktop) and a mobile touch-target pass.

v0.7.0 (2026-06-15)

A Sculpt update — the harmonic editor is now honest, and the resonant-noise mode grew up.

Sculpt

• What you draw is what you hear. The drawbars map straight to the sound — no more hidden weighting where two bars at the same height held different levels, or upper partials that were audible but invisible. 100% is always at the top, and every bar pulls the full height.
• Quiet partials are dialable. A gentle taper gives low levels real height, so “a little” and “none” are easy to tell apart and place. The editor is taller, too.
• Your sculpt curve now saves. Hand-drawn spectra travel with Copy/Paste presets and with your DAW project — they used to be lost on reload.
• Morph shapes are true spectra. Saw and square taper at 1/n, triangle at 1/n², pulse is flat — so the shapes look like the waveforms and leave headroom to push an upper partial up.

Resonant Noise

• Stretch and the Harmonic Envelope now shape the resonant partials, like they do the additive engine — so the breathy/resonant mode retunes and swells with the rest of the synth instead of sitting still.

Coming next

• More of the synth (Converge, Harmonic Gate, Overtone Scan) acting on the resonant partials, and an Air control for the breathy mode.

v0.6.0 (2026-06-12)

New

• String scope mode — draws the synth’s live harmonics as a vibrating string, with three views to flip between, swelling and decaying with each note.

Fixes

• Partials Advanced sliders now respond on desktop.

v0.5.0 (2026-06-03)

The chord-function Harmony Wheel is now built into the synth, with a full scope overhaul.

New

• Harmony scope mode — the BKS Harmony Wheel’s functional-harmony display, right inside the synth’s scope. It reads what you play and shows each chord’s role (I, V7, V/V, ♭VII, vii°…) and the active space (HOME / SUB / PAR / REL / BLUES). Click a wedge to play that chord. The key follows the synth’s Scale Root; “lock wheel” freezes the space; bonus wedges appear on demand.

Scope

• Goniometer — the lissajous now rotates 45° (mid vertical, side horizontal) with a phase correlation meter along the bottom.
• True-sawtooth oscilloscope — plots the full L+R mix (previously showed odd partials only at stereo width).
• Steadier display — fills the scope at any level without pumping, round circles, width-keyed mono/stereo.

Other

• Standalone MIDI volume (CC7) — your controller’s volume fader now works in the standalone app (the plugin defers to the host in a DAW).
• Click a scope title to jump straight to that view; the key badge is now a dropdown key picker.

Note: the plugin is now named BKS Harmonic (was “BK Harmonic”). Saved DAW projects keep working — only the display name changed. macOS (Universal); Windows VST3 coming shortly.

v0.4.0 (2026-05-18)

New

• Harmonic Envelope — a new section: pick a group of partials in a 24-cell grid, then shape that group’s level with its own ADSR, plus Fade, Depth, and Attack Height controls. A polarity invert flips it — the group blooms up on release instead of fading.
• Source 2 “Synth” mode — a detuned, independent double of the partials matrix for unison and chorus, with a Track Morph toggle to follow or ignore Converge / Stretch / Unison.
• Global Transpose — a new Output control with octave buttons for exact jumps.
• Filter “Key” slider — true keyboard tracking (bipolar), scaling cutoff with note pitch. Modulation-routable.

Modulation

• Every envelope is now per-note. The Harmonic Envelope and Env 1 shape each note independently from velocity, envelopes and Note position. Harmonic Envelope attack height is now a modulation target too, with a floor so velocity can’t drive a soft note to silence.
• Env 2 → VCA and VCF — Env 2 can now shape amplitude and filter cutoff per voice, with its own bypass toggle.
• Env 2 and Harmonic Envelope polarity invert — inverted, the envelope blooms up on release.
• Partials Floor toggle in the modulation gear popup.

Sound

• Phase is now bipolar. Positive sweeps a uniform pitch bend (harmonic ratios preserved); negative sweeps a spectral tilt — two distinct motions from one control.
• Noise envelope range widened to 1 ms – 10 s — low attack values are noticeably snappier.

Fixes

• Fixed the static blowup. If the signal goes out of range the FX chain now recovers instantly, instead of circulating garbage until it decays.
• Fixed CPU overload from voice stacking. Fast and repeated notes used to pile up voices that never got reclaimed; superseded voices now fast-release and inaudible decayed voices are freed.
• Fixed clicks on filter sweeps — filter coefficients now interpolate every sample instead of stepping at block boundaries.
• Fixed zipper noise on Phase sweeps — the phase offset now interpolates every sample.
• Fixed dead short attacks — Env 2 and the Noise envelope silently skipped any attack shorter than ~100 ms; they now work down to 1 ms.
• Fixed the Sum button — it was wired to mono/legato by mistake; it now does a true stereo-to-mono sum (the scope still shows the pre-sum stereo).

UI

• Per-note matrix animation — playing a note fires a landing-burst marker at its spot in the partials matrix, fading over about half a second.
• New Source 2 selector with a Synth-mode reticule icon.
• Filter “Track” slider renamed “Scan” — it pulls cutoff toward the scanner’s selected partial; the old label and help text were wrong.
• Help-text pass throughout, including the modulation gear (drag to adjust the focused route, Alt-click to bypass, Shift-click to zero).

v0.3.9 (2026-05-12)

Audio

• Noise generator now scales with velocity by default — soft notes get soft noise, no more constant hiss on quiet keys.

UI

• New V (voices) and O (oscillators) meters in the scope, next to L/R level. Hover any bar — including the limiter triangle — for a one-line explanation.
• Polyphony slider in Settings (1–16, default 8) — cap voice count to control CPU vs. dense-chord coverage.
• Mod-matrix gear feedback: Fold and Partials gears in the partials matrix now color-shift to their assigned mod source and draw a small arc showing amount. Empty routes stay gray.

Quality of life

• Patch share button now copies a markdown link (“BK Harmonic patch”) instead of a giant URL. Paste handler still accepts bare URLs.

Coming next: still chasing the onset click through the filter under some conditions.

v0.3.8 (2026-05-12)

Audio

• VCA release fix: notes always fade to zero on key-off, regardless of VCA depth. Previously, low VCA settings let voices play at near-full volume through the entire release phase before snapping off.
• VCA default raised from 75 → 100 (full envelope by default on fresh patches).

UI

• VCA help text updated: “0 = flat (organ). 100 = full envelope. Release always fades to zero.”

v0.3.7 (2026-04-22)

Audio

• VCA restored to linear blend — eva=100 now means full envelope depth (matches legacy preset semantics). No more power-curve “punch mode” at high values.

UI

• Oscilloscope sawtooth display fixed (coherent partial phases on fresh notes)
• Shift+hover partial mute restored (works as modifier on top of hover mode pill)
• Per-button help text for scan section (wave shapes, retrig, 1-shot, mode, sync)
• Modulated slider position more visible (contrasting line, taller, dark border)

v0.3.6 (2026-04-17)

Audio

• Per-sample envelope processing (smoother note-on/off transitions)
• Voice steal cleanup (no more amplitude burst on reused voices)
• Fold and converge drag smoothing (per-sample layer weight interpolation)

Scanner

• Scale mode fixed: filters partials by actual played note pitch class
• Mode button shows ALL / NOTES / SCALE with distinct colors

v0.3.5 (2026-04-09)

Critical Fix

• Eliminated speaker-damaging gain spike during overtone scan (uninitialized partial gain array caused 10^16 amplitude spikes when scanner re-spotlighted a previously muted partial)

v0.3.4 (2026-04-09)

Audio

• Envelope clicks eliminated (per-sample interpolation at all ADSR breakpoints)
• Fold/open zipper eliminated (per-sample partial gain interpolation)

• Speculative fixes from debugging cleaned up

v0.3.3 (2026-04-07)

Fixes

• Same-note retrigger preserves envelope (no longer cuts release tail)
• Releasing voices no longer stolen (release tails play out naturally)
• Onset ramp changed from linear to exponential (removes zipper on note attack)
• Gain staging: velocity normalized to 0-1 range (volume slider usable across full range)
• Scanner shape smoothing extended (click only in top 10% of slider)

UI

• “PARTIALS: SOLO” label on hover mode button
• Vodka and Sub controls removed (pending redesign)

v0.3.2 (2026-04-07)

Fixes

• Envelope timing restored (attack, decay, release were too fast in v0.3.0)
• Phase coherence restored (sawtooth displays correctly in oscilloscope)
• Decay-to-sustain transition smoothed on all three envelopes (no click at breakpoint)
• Debug file access removed (no more Desktop/Downloads permission prompts)

New

• Per-slider help text (hover any control for a description of what it does)
• Noise ADSR envelope with curve display and draggable handles (same UI as Env 1/2)
• Windows VST3 updated to current codebase

v0.3.0 (2026-04-05)

First signed and notarized release. macOS 11.0+ (Big Sur and later).

New

• Pluck — per-voice filter bypass transient. Bypasses the lowpass filter for a configurable duration on each noteOn, creating a bright harmonic attack that settles into the filtered tone. Lives in the Noise section, routable via mod matrix.
• Noise ADSR — dedicated per-voice envelope for the noise generator, independent from Env 1. Full ADSR with curve display and draggable handles. Enables breath attacks, percussive noise bursts, and sustained noise textures.
• LFO2 delay — paraphonic fade-in for LFO2 modulation. Resets on the first note of a phrase, cubic ramp curve, 50ms to 10s range.
• VCA intensity — bipolar envelope depth control. Below 75% flattens the contour, above 75% exaggerates it. Default 75% = normal envelope.
• 4 new presets: Koto Guitar, Spooky Drops, Strange Sitar, Brashness

Sound

• Envelope timing matched to web version (attack, decay, release all use correct formula)
• Envelope applied per-sample (preserves exponential release curve)
• Zero attack = instant onset at noteOn
• Filter cutoff resets on preset switch (eliminates first-note brightness bug)
• Reverb and delay buffers cleared on preset switch (no bleed between presets)
• Limiter lookahead prevents first-note overshoot
• Random phase initialization prevents constructive interference transient
• Converge and stretch smoothed to prevent zipper noise
• Scanner shape slider scales smoothing: click at max isolate, smooth crossfade when backed off
