IN YOUR SESSION
Move from an idea to an editable patch.
Build across oscillators, filters, modulation and effects, or drop audio into Anneal and let an evolutionary search breed four ordinary, editable patches toward it on your own machine. The result is a starting point for editing, not a promise of exact resynthesis. Either way you end up in the same place: a patch made of ordinary parameters you can keep shaping.
A CLOSER LOOK
Inside Kiln.

Any source, any slot
OSC 1 switches between WT, ANA and SMP, loads a wavetable, and reads level, table and shape over its unison, pan, octave, semitone, fine, pulse width and FM row.

Glass on filter 2
Filter 2 is set to GLS. Cutoff and resonance sit above the Glass row: MAT 0.68, POS 0.62, SIZE 0.6, DMP 0.5, mixed in at 0.45.

The modulation matrix
Eight routes filled on the MATRIX page. Each row picks a source and a destination from a menu, and the tabs above page the matrix in eights.
All features & controls
- Three oscillator slots: wavetable, analog morph or sample (WAV, AIFF or FLAC) in each
- Dedicated sub and noise sources beside the three slots
- 16-voice unison per slot; FM between slots
- 80 in-house wavetables, zero third-party content
- Two filter slots: SVF, ladder, comb, formant or Glass
- The ladder self-oscillates in tune within plus or minus 0.1 cents across five octaves
- Per-voice analog drift is seeded: a fresh instance plays the same notes with the same drift
- Glass modal resonator as a first-class per-voice filter: Material, Size, Position and Damp, with Shimmer as a modulation target
- 82 factory Glass patches carry the signature timbre
- 48-slot modulation matrix; depths automatable and themselves modulatable
- Four DAHDSR envelopes, four LFOs, random and chaos sources
- Four macros as matrix sources: every factory patch routes macro 1, and 362 also route macro 2
- Nine effects; Ultra quality when the host reports offline rendering
- Anneal: fully local sound-guided patch search returning four editable patches
- Purchased licenses work offline; trials require an internet connection
- MPE per-note bend (the standard 48-semitone range), pressure and slide; bend accuracy measured at minus 0.2 cents
- MTS-ESP microtuning, plus Scala .scl scales and .kbm keyboard maps saved with the session
- 554 factory presets, tagged by category
- 28 MPE patches and a Learn tag in the library
- AU, VST3 and AAX on macOS; VST3 and AAX on Windows
554 presets, tagged
The library searches by name and filters on tag chips: ALL, BASS, LEAD, PAD, KEYS, PLUCK, GLASS, FX. Every row is marked FACTORY or USER.
Anneal
Drop audio into Anneal. It analyzes the first four seconds and searches locally for editable patches with a related tone and envelope.
Type the value, in Hz
Click a readout and type in its own unit. The FX EQ's MID FREQ field is open with 820 entered; Return commits, Escape cancels.
Tuning and recovery, measured
| Claim | Measured |
|---|---|
| The ladder tracks | Self-oscillates in tune within plus or minus 0.1 cents across five octaves |
| MPE bend lands | Bend accuracy measured at minus 0.2 cents over the standard 48-semitone MPE range |
| Scala tuning lands | A +50 cent .scl table plays A4 at +50.000 cents in the test suite |
| Anneal recovers | Self-recovery eval: 6 of 6 within the family bar |
| Seeded drift | Per-voice analog drift is seeded, so a fresh instance plays the same notes with the same drift |
Put it to work.
Start from a reference sound
Drop audio into Anneal and choose from four editable patches generated on your own machine.
Basses and leads
Three oscillator slots with 16-voice unison each, dedicated sub and noise, and FM between slots for weight and bite that stay tuned.
Textures and keys
The Glass modal resonator turns any source physical: Material, Size, Position and Damp on the panel, Shimmer as a modulation target, per voice, with 82 factory Glass patches to start from.
Performance
MPE with per-note bend, pressure and slide, bend accuracy measured at minus 0.2 cents, four macros as matrix sources, and 28 dedicated MPE patches in the library.

What is Anneal?
A local audio-analysis and patch-search workflow. Drop a sound and an evolutionary search breeds four ordinary, editable patches toward it. It is a starting point for editing, not exact resynthesis.
Does Anneal need an internet connection?
Anneal’s analysis and search run locally. Purchased licenses work offline; trial licenses need a live internet connection, and the plugin checks in every few minutes.
Which oscillator types are present?
Wavetable, analog morph or sample in each of the three slots, plus dedicated sub and noise sources. SMP plays a WAV, AIFF or FLAC file you click to load or drop on the OSC panel; the session saves a copy of it, or a link to the file past 16 MB per patch.
Does the ladder filter track?
It self-oscillates in tune within plus or minus 0.1 cents across five octaves. Per-voice analog drift is seeded, so a fresh instance plays the same notes with the same drift.
Which formats and platforms?
AU, VST3 and AAX on macOS; VST3 and AAX on Windows. Check the system requirements and your DAW’s supported formats.
Is there a free trial?
Yes. Every released Vitric plugin has a free 3 day trial with every feature available during the trial window. Trials need a live internet connection; the plugin checks in every few minutes. Purchased perpetual licenses work offline. Get the installer from the downloads page and request your machine-bound trial license on the trial page. At the signed expiry the plugin’s output goes silent until you install a purchased license or a valid subscription grant. The plugin can still load, so projects and saved settings are not deleted.
