Coming

motion lanes don’t follow the Morph crossfader yet
under wide microtunings, draw the motion-lane bars small to sweep the full ratio span

The two clicks are gone. The envelope no longer ticks at note release, and recycling a voice for a new note no longer cuts the old one off.
Per-voice envelope modulation. The envelope can drive ratio, fold, and cutoff now, alongside the two LFOs.
Velocity to timbre. Play harder for brighter FM and more open filters.
A Pluck envelope model, for one-shot percussive shapes.
The Morph crossfader interpolates inside the engine. The sound moves between A and B, not just the panel.
New palette, tuned in OKLCH. The LFO and motion modules carry their route color, and stateless values read in a warmer ink.

Fixed window-resize flicker on external monitors.
Presets and tunings now live in one folder under your user library, set up from the plugin on first launch.
The init patch is the single source of truth for the default sound.

Signed and notarized macOS installer. Intel Macs unblocked.
Crossfader stutter and the Morph feedback loop fixed. The DAW keeps automation authority.
Alphabetical preset sort. Save enabled on modified factory presets.
A branded installer welcome screen.

Filter-lock resonance boost and multi-octave lock frequencies. 26 presets.
Ratio lock and filter lock show without an MTS-ESP master connected.
Drive saturation reworked, envelope attack made punchier.
Windows: DPI-aware initial window size, keyboard focus returns to the DAW, LFO slew no longer eats amplitude at higher rates.
Branded installers for macOS and Windows.

The first release. An 8-voice FM synthesizer that locks its ratios to the scale you load: the Petal Oscillator, a wavefolder, dual filters with scale-locked resonance, two LFOs, two motion lanes with ties, per-voice reverb, Morph A/B, the Seed randomizer, and MTS-ESP and Scala tuning.
