A non-deterministic composition machine

Noemi - node-based composition interface with mastering EQ, mixer, and modulation routing

Version 1.0.0 beta 4 —

Pre-release builds for testing. Report bugs to support@tweakbench.com or on Discord. The best way to support this development is to buy some Tweakbench plugins!

Noemi is a generative music DAW. Instead of a traditional linear timeline, you wire together composition building blocks — patterns, generators, instruments, transformers, and effects — into a node graph that creates evolving music in real time. Ships as a standalone app and as audio plugins (VST3, AU, CLAP, LV2).

What's Inside

7 Composition Sources

Pattern (4 polyrhythm playheads), Generator (probabilistic rules with 30+ scales), Rhythm (8-lane step sequencer), LiveCode (TidalCycles-inspired notation), Waveform, Slicer, and Granular synthesis

5 Built-in Instruments

Chirusa (4-osc subtractive), SimSim (wavetable morphing), Cantia (formant voice), Leeroy (drum synthesis), Ostion (drum sampler) — plus VST3/AU/CLAP/LV2 plugin hosting

Effects & Mastering

7 built-in effects with 56 presets. Mastering chain: Parametric EQ, Stereo Imager, Multiband Dynamics, Maximizer. 2 send/return bus effects. External plugin hosting.

12 MIDI Transformers

Arpeggiator, Chord Generator, Scale Quantizer, Euclidean Rhythm, Markov Chain, Style Learner, Probability Gate, Humanize, and more — all chainable

Deep Modulation

11 modulation source types (LFO, Envelope, Step Seq, Random, Follower, Sidechain, Macro, MIDI, OSC, MiniNotation, Automation) with per-route rate and response curves

Performance & Arrangement

16-slot scene system with crossfade. Full-screen Performance View. Song arrangement engine with 10 templates. Ableton Link sync.

Expression & Tuning

MPE per-note pressure, slide, and pitch bend. MTS-ESP microtuning with SCL/KBM loading. MIDI I/O, OSC control, CC binding with Learn mode.

Export & Workflow

Single mix or multitrack WAV/MP3 export. Per-section rendering. Preset browser with patch export/import. Autosave with crash recovery.

Cross-Platform

macOS (Universal), Windows (x64), Linux (x86_64), iOS (iPad). 4 color themes. Customizable shortcuts. VoiceOver accessibility.

Changelog

1.0.0 beta 4 — 2026-05-25

MIDI input recording with count-in and metronome, Windows LV2 scanning fix, JUCE 8.0.13 upgrade, and transport stability fixes

MIDI input recording (FL Studio style): the Record button on a Pattern or Rhythm arms it for live MIDI input. Play the first note to start recording from the top, or press Play for a 4-beat count-in before recording begins
New metronome with an accented downbeat, toggled from the transport bar with a volume knob — it clicks during playback and through the recording count-in
Fixed all LV2 plugins failing to scan on Windows
Upgraded to JUCE 8.0.13: faster macOS scope/waveform redraws, Direct2D plugin-window resize and hi-DPI fixes on Windows, better Apple Pencil hover on iPad, and more reliable MIDI output
Fixed a crash during scene crossfades at song-structure boundaries and an audio blip after pressing Stop
Panic button now also stops the transport, and the arrangement toggle lights up after generating song structure
Desktop installers: macOS ships a signed, notarized .pkg and Windows ships a setup installer (which bundles the Visual C++ runtime)

1.0.0 beta 3 — 2026-05-16

Modulation matrix and module inspector UI overhaul, replace node, cable rendering fix, AU scanner crash protection, modulation performance fix, and Ableton Link Audio support

Ableton Link Audio support: Link Audio mode publishes Noemi's post-mastering stereo mix to other Link Audio peers on the LAN, and a new Link Audio Input node can subscribe to peer channels
Modulation processing now only touches parameters with active routes, avoiding huge per-tick scans on plugins with thousands of automatable parameters
AU plugins now scan out-of-process so a crashing AU takes down the scanner child process instead of Noemi
Modulation matrix redesigned with visual source cards, draggable ADSR editor, waveform buttons, live scope strips, route cards, cascading parameter picker, destination filtering, and a persistent resizable panel
Module inspector panels rebuilt with compact rotary knobs, tighter sections, ADSR shape editors, and shorter layouts across synths, samplers, generators, transformers, live code, waveform, granular, and internal effects
Right-click any node and choose Replace with... to swap it for another node in the same category while preserving connections and canvas position
Pattern and Rhythm editors restored dedicated Library buttons and moved transforms / MIDI actions into compact menus
Adding a Rhythm module now loads a random drum clip from the drum library
Fixed cable clipping on macOS for highly curved backward and bottom-edge connections
Fixed desktop right-click context menus, 120Hz/144Hz VU meter animation speed, oval knob rendering, and a modulation-panel crash when randomizing or loading projects mid-playback

1.0.0 beta 2 — 2026-04-01

Mastering chain, bus effects, independent mixer channels, LV2 plugin hosting, and plugin format support (VST3/AU/CLAP/LV2)

Mastering chain with 4 stages: Parametric EQ with spectrum analyzer, Stereo Imager with animated visualization, Multiband Dynamics, and Maximizer — each with presets
Bus effects: 2 send/return effect buses on the mixer with per-channel send knobs and return controls
Independent per-channel mixer: each channel has its own volume, pan, mute, and solo with editable names
LV2 plugin format support alongside VST3/AU/CLAP on all desktop platforms
Plugin Settings dialog for managing scan paths per format
Noemi now available as VST3, AU, CLAP, and LV2 plugin in instrument and effect variants
Export filenames include tempo and master key
Fix crash on macOS 11 (Big Sur): heap corruption in sampler and font rendering
Fix crash when opening projects with deleted master track
Fix pendulum playback and note truncation issues at loop boundaries
