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.
Rivet & Patina
Six Rust CLAP plugins for writing, designing and mixing bass music.
| Plugin | Purpose | Guide |
|---|---|---|
| Rivet | Tell a MIDI motif as a story on a storyboard of roles, with joined seams | Rivet |
| Patina | Smooth harsh resonances while retaining tone and transient character | Patina |
| Anvil | Give every bass note the same clean sub: one level, one start phase | Anvil |
| Crucible | Capture the last bars, slice them and export clean, key-labelled samples | Crucible |
| Lathe | EQ the harmonics of the played note: a cut on harmonic 3 stays on harmonic 3 | Lathe |
| Temper | Distort every note the same: level and tone filters follow the note | Temper |
The names come from metalwork: a rivet joins pieces; patina changes a surface while leaving its character; an anvil is the solid base everything is struck on; a crucible melts material down to be cast again; a lathe turns a piece so each cut lands the same all the way round; tempering sets how hard and how tough a metal ends up. They share a Rust foundation and keep their own musical purpose, code, documentation, and version. Ideas for further plugins are collected in docs/ideas.md.
Install
Download the desired plugin's Windows ZIP from its Gitea release. Extract it
and copy its .clap file (Rivet.clap, Patina.clap, Anvil.clap,
Crucible.clap, Lathe.clap or Temper.clap) into:
C:\Program Files\Common Files\CLAP\
In FL Studio 2024.1 or newer, open Options → Manage plugins, enable Verify plugins, and Find installed plugins. Load Rivet in the Channel Rack; load the others in mixer effect slots.
Normal branch/PR pipelines also provide a combined Windows preview ZIP in the
windows job. Releases are separate: tags such as rivet-v0.4.0,
patina-v0.2.0, anvil-v0.1.0, crucible-v0.1.0, lathe-v0.1.0 and
temper-v0.1.0 publish independently. See release workflow.
These names replace Motif Storyboard and Resonance Compressor. Their CLAP IDs and saved-state identifiers are preserved; replace old scanned copies and rescan.

The root Cargo workspace contains the engines and supporting tools. Each CLAP wrapper has an independent workspace and lockfile so SDK dependencies stay separate. Development and testing covers the commands.

Windows is the release target. Linux remains useful for tests, cross-compilation, and headless editor previews. FL Studio routing, native window behavior, and artistic listening still require manual checks in the target setup.
