A dark, dense, keyboard-friendly desktop DAW for electronic producers and mix engineers.
Status: alpha. Resamper is in early development. The current release is v0.2.3 — M1.2 Fixes, published as an alpha pre-release. Expect missing features, rough edges and project-format changes — don't trust it with your only copy of a song yet.
Resamper takes you from idea to structure to mix in a single window. Its core principle: sound design lives in the device chain, mixing lives in the mixer — two separate chains, with a signal path you can always see.
These images come from the product design (
design/design.pen) and show where Resamper is heading. Several features in them belong to later milestones — see the roadmap for what's in v0.2.3 today.
- Arrange — audio and MIDI tracks, clips you can move, resize, split, duplicate, loop-extend and consolidate; a Time Selection across every track; a grid that subdivides as you zoom; zoom, lane height and Follow.
- Record — audio recording with input selection, live waveform and takes; MIDI recording from a MIDI input; count-in (Shift-click Rec to skip it).
- Edit MIDI — piano roll note editing and quantize.
- Shape sound — a per-track device chain in the detail view: EQ Eight and Compressor edited on their graphs, and VST3 / AU / CLAP plug-ins in their own windows.
- Host plug-ins safely — each plug-in runs in its own process: a crash bypasses only that device and Reload brings it back; a plug-in that fails to scan can be retried.
- Mix — volume, pan, mute, solo, stereo meters, 8 insert slots per channel with bypass and reorder; Bus Strips with their own inserts and Sends.
- Browse — a library browser with search, categories, sample preview and drag-to-track.
- Stay safe — autosave and crash recovery.
- Stay current — in-app updates; the UI in English or Turkish.

Resamper's own source code is released under the MIT License. That grant covers those files on their own.
A build of the app also contains JUCE (AGPLv3, or a commercial JUCE licence) and Tracktion Engine (GPLv3, or a commercial Tracktion licence). GIN is BSD-3-Clause and melatonin_inspector is MIT. The MIT licence does not sublicense JUCE or Tracktion.
You may run the app, including for paid work. You may also share and sell a build when that distribution stays under the AGPL and the GPL and the corresponding source is offered. A closed-source build needs your own JUCE licence and your own Tracktion Engine licence. Each is bought from that vendor, and one does not include the other. Both can be taken out before any sale.
This is a summary of those texts, not legal advice.

Resamper is built on JUCE + Tracktion Engine
- GIN. CONTEXT.md defines the domain language.
| Path | Pin |
|---|---|
external/tracktion_engine |
Tracktion Engine 3.5.0, commit 964583ee (3.5.0 plus an upstream fix for a null ProjectItem crash when saving an Edit outside a Tracktion project) |
external/tracktion_engine/modules/juce |
JUCE 8.0.13 (8.0.13-7-g37c894f8), pinned by Tracktion |
external/gin |
GIN, commit ea795541; only the gin module is built (other modules are added when code needs them) |
external/melatonin_inspector |
melatonin_inspector, commit 9c483f86 (module 1.4.0); the Developer Mode component inspector |
Requires CMake ≥ 3.22, Ninja and Xcode command-line tools (C++20).
git submodule update --init external/gin external/melatonin_inspector external/tracktion_engine
# Tracktion's .gitmodules points JUCE at an SSH URL; use HTTPS unless you have GitHub SSH keys:
git -C external/tracktion_engine config submodule.modules/juce.url https://github.com/juce-framework/JUCE.git
git -C external/tracktion_engine submodule update --init modules/juce
cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Debug
cmake --build build- App:
build/Resamper_artefacts/Debug/Resamper.app - Tests (headless, no audio device):
build/ResamperTests_artefacts/Debug/ResamperTests [suite-name-filter], orctest --test-dir build
Source/Engine/ EngineManager, ProjectManager, ApplicationModel facade — the only code that sees Tracktion
Source/Commands/ Command registry, model Commands, ApplicationCommand ↔ Command ID table
Source/UI/ Theme, UI State, Arrangement, Mixer, Detail View, MainWindow, Developer Mode tools
Source/App/ Application entry point
UI/themes, UI/fonts Theme and font files (embedded in Release; read from the source tree in Debug)
Tests/ Headless tests over the Command registry / Application Model seam
Source/UI, Source/Commands and Source/App are compiled without Tracktion on the include path, so
"UI never includes Tracktion headers" is a compile error rather than a convention.
In Debug builds, the theme is read from UI/ in the source tree. Saving a theme file re-styles the app; so does:
- Reload Theme — Cmd+Alt+Shift+T: re-styles in place
- Developer Overlay — Cmd+Alt+Shift+D: shows the status bar and opens melatonin_inspector in its own window (hidden by default; the design has neither)
Issues are tracked on GitHub. Releases follow Semantic Versioning; each PRD milestone ships as a minor release until 1.0.0 — see CHANGELOG.md.
Commit subjects are <gitmoji> <type>(<scope>): <summary>, e.g. 🐛 fix(undo): …; CI checks every
commit a pull request adds. Release notes group commits by <type>.
- Bump
project(Resamper VERSION …)inCMakeLists.txt, move[Unreleased]inCHANGELOG.mdto a dated[x.y.z]section with its compare link, and commit🔖 chore(release): vx.y.z. - Tag it with a title and push:
git tag -a vx.y.z -m "vx.y.z — <title>" && git push origin main vx.y.z.
The Release workflow checks the tag against the CMake version, builds
and tests the app, and publishes the release: the CHANGELOG section, the app signed and notarized in a
DMG, and the commit list from git-cliff (cliff.toml; preview it with
git cliff --latest). Tags are plain vX.Y.Z; 0.x releases are published as alpha pre-releases.
Resamper's own code is MIT. A binary also contains JUCE (AGPLv3 or a commercial JUCE licence) and Tracktion Engine (GPLv3 or a commercial Tracktion licence); GIN is BSD-3-Clause and melatonin_inspector is MIT. The embedded lucide icons are ISC / MIT (Source/UI/Controls/Lucide-LICENSE.txt). What that means for distribution is in the public License section.
