A lightweight DAW with the FL Studio workflow.
Channel Rack, Piano Roll, Playlist and Mixer in C++20 + JUCE 8, built to run well on any PC.
Windows, macOS and Linux.

_{Formerly “LYNX”: renamed LYNX SHARE in v0.1.20 (it was easy to confuse with the Lynx text web browser). Old links to github.com/Ka1-S/LYNX redirect here; your settings and projects stay where they are.}

_{LYNX SHARE's own demo project (LYNX.exe --showcase) in the 0.1.19 workspace: browser, Piano Roll, Channel Rack and Mixer.}

LYNX SHARE ships native plugins inspired by the third-party plugins producers use most, next to its clean-room FL Studio natives. 24 dedicated LYNX SHARE engines are in, more are being built, and a project that uses one of the 56 originals below opens with the LYNX SHARE equivalent when the original is not installed (its settings are kept and come back once it is; see PLUGIN_FALLBACK.md).

_{Product and company names are trademarks of their respective owners. They are used only to describe compatibility and the role each LYNX SHARE engine plays. LYNX SHARE is not affiliated with, endorsed or sponsored by any of them and contains none of their code, presets, graphics or audio.}

_{Playlist: pattern, automation and audio clips with a clip menu on right-click (split, chop, merge, reverse, normalize, fit to tempo and more).}

Step sequencer with per-channel volume, pan, mute and solo, swing, multiple patterns (name, colour, length, clone), cut groups, arpeggiator and the PC keyboard as a piano.	Configurable snap, chords and scales, 16 note colors, note groups, a chord readout, select tools (invert, odd/even, random, overlapping), quantize, slide and porta notes, velocity/pan/pitch lane, .mid import and export.
Up to 127 inserts, sends with levels, 10 effect slots with dry/wet per track, built-in EQ (or a clean mixer with none), PDC, smart disable and sidechain (here the bass compressor listening to the kick). Choose how many inserts new projects start with and show only the used ones.	3 oscillators (including a band-limited harmonics oscillator), LP/BP/HP/BS filter with keytracking, FM and ring modulation, envelopes, 4 LFOs, kick sweep, mono and portamento.
Draggable handles, shelves, 12–48 dB/oct cuts, band-pass and notch, with the response drawn in real time.	Any knob or fader (channel, mixer, effect, plugin parameter) becomes a clip with points and curves; MIDI controllers can be linked to any parameter.

LYNX SHARE's native engines are clean-room re-implementations of FL Studio's native plugins, each checked against the original running unmodified. The full list — every engine, what it is compatible with, its status and what is still missing — is in docs/PLUGINS.md.

Featured — the plugins FL Studio users reach for most, all at Exact or Near-exact quality in LYNX SHARE:

What each one does, how you get it (any insert or from an .flp) and the whole list are in docs/PLUGINS.md.

All built-in plugins:

Exact = bit-identical to the original on every installation state tested; near-exact = the rest below about −100 dB; close = same algorithm, within −60 dB. Plugin names are Image-Line's trademarks, used only to describe compatibility; LYNX SHARE is not affiliated with Image-Line.

LYNX SHARE reads the .flp format directly and converts everything that has an equivalent:

• Structure: channels, real samples (including the Ogg Vorbis WAVs and WavPack files shipped with FL), patterns, slide/porta notes, every arrangement, markers, time-signature changes, automation and controller links.
• Mixer: routing, levels, sidechains, track EQ and native effects with their saved settings (Parametric EQ 2, Limiter, Compressor, Reeverb 2, Delay 3, Maximus, Gross Beat, Effector, Love Philter, Frequency Splitter, Patcher, Pitcher, Vocoder, Newtone/Newtime and more).
• Generators on FL's own engines (checked against FL's DLLs, most of them bit for bit): 3x Osc, SimSynth, MiniSynth, DX10, Kepler, PoiZone, Toxic Biohazard, Transistor Bass, Autogun, Plucked!, BeepMap, Sawer, Granulizer, Drumaxx, FL Slayer, FL Keys, Fruit Kick, Kick, BassDrum, Sakura, Drumpad, BooBass, Fruity DrumSynth Live, GMS, Morphine; Sytrus, Harmless, Harmor (including image synthesis) and Ogun on engines rebuilt from the plugin state. Built-in sounds and tables are read from your FL installation, never shipped with LYNX SHARE. DirectWave runs on its own exact engine (filters, modulation matrix and effects); FPC, Slicex, Fruity Slicer and Wave Traveller play as samplers through FL's own interpolators.
• Exact native effects: Parametric EQ 2, EQUO, Limiter, Compressor, Multiband Compressor, Maximus, Soundgoodizer, Reeverb 2, LuxeVerb, Convolver, Delay 3, Delay Bank, the chorus family, Flangus, Flanger, Fast Dist, WaveShaper, Soft Clipper, Stereo Shaper/Enhancer, Transient Processor, Frequency Splitter, Fast LP, Free Filter, Fruity Filter, Pitch Shifter, Love Philter, Fruity Vocoder, Vocodex, Hardcore, Distructor, Multiband Delay, Gross Beat, Effector, Vintage Phaser, Pitcher and more reproduce FL's algorithms; how each one was decoded is documented in docs/analise/.
• Third-party plugins: VST3/CLAP plugins inside the Fruity Wrapper are swapped for the same installed plugin, preset included.

A report lists what was converted, what is approximated and what was left out. FLEX packs are encrypted and are never opened (the channel gets a synth patch chosen by preset name).

Every release on the latest release page has builds for all three platforms (<v> is the version, e.g. 0.1.10-alpha):

Release files are built from the tagged source by GitHub Actions (release.yml) and listed with their SHA-256 in SHA256SUMS.txt. Releases up to 0.1.7 are Windows-only; up to 0.1.12 the AppImage was named LYNX-<v>-linux-x86_64.AppImage and needed glibc 2.39.

Windows. Run the installer: it needs no admin rights, adds Start-menu/desktop shortcuts, opens .lynx projects and offers LYNX SHARE in Open with for .flp without changing FL Studio's default. Prefer no installer? Extract the portable .zip and run LYNX.exe. Both include a demo project (Demo.lynx). The executable is not code-signed yet, so SmartScreen may warn on first launch (More info → Run anyway); see Code signing policy.

macOS. Open the .dmg and drag LYNX SHARE to Applications. The app is not notarized by Apple and has no Developer ID signature (ad-hoc only), so the first launch needs one extra step: right-click (Control-click) LYNX SHARE in Applications → Open → Open. On macOS 15 Sequoia or newer, try to open it once, then go to System Settings → Privacy & Security and click Open Anyway. Or, in Terminal:

xattr -dr com.apple.quarantine /Applications/LYNX.app

macOS asks for microphone access the first time you record.

Linux. Needs X11 or XWayland; audio goes through PipeWire directly (or JACK, or ALSA), see docs/LINUX.md. For the AppImage:

chmod +x LYNX-*.AppImage
./LYNX-*.AppImage

Some distributions need libfuse2 to run AppImages (libfuse2 on Ubuntu 22.04, libfuse2t64 on 24.04, fuse2 on Arch, fuse-libs on Fedora); otherwise use the .tar.gz: extract it and run ./install.sh, which installs LYNX SHARE for your user under ~/.local with a menu entry, an icon and the .lynx file type (./install.sh --uninstall removes it again).

Opening FL Studio projects (.flp) works on every OS; the FL Studio integration only adds FL's own samples and plugin paths when an installation is found.

On first start a short setup wizard (skippable; Options > Setup wizard reopens it) picks the language, tests the audio device and lists the plugin folders — the standard VST3/CLAP folders plus the ones FL Studio uses on the same PC — and scans them in the background. If FL Studio is installed, .flp projects use the very plugin files FL uses (read from its plugin database) and find samples in FL's folders; a plugin LYNX SHARE doesn't know yet gets a quick scan of just its file (details).

LYNX.exe also runs headless, which is how everything is verified without opening windows. On macOS and Linux the binary is LYNX (/Applications/LYNX.app/Contents/MacOS/LYNX on macOS); the options are the same:

LYNX.exe project.lynx                          open a project (.lynx, .flp or .mid)
LYNX.exe --export project.flp out.flac         render the song (wav/flac/ogg)
LYNX.exe --render project.flp out.wav 20       render 20 s of the current pattern (24-bit WAV)
LYNX.exe --selftest report.txt [demo.lynx]     self-test without an audio device
LYNX.exe --snapshot prefix project.flp         draw the UI (and its windows) to PNG
LYNX.exe --showcase out.lynx [pattern]         generate the demo project used in these screenshots
LYNX.exe --plugintest plugin.vst3 rep.txt      test a VST3 or CLAP plugin
LYNX.exe --sandboxtest plugin.vst3 rep.txt     test a plugin in a separate process (including a hung one)
LYNX.exe --scantest folder rep.txt             scan a folder for plugins (separate processes)
LYNX.exe --fldb rep.txt [project.flp] [--scan] FL Studio found here, its plugin database, a project's plugin matches
LYNX.exe --devices rep.txt                     list audio drivers and outputs
LYNX.exe --devicetest "ASIO" "driver" rep.txt  open a driver for 1 s of silence and report it
LYNX --uiperf project.flp rep.txt             time the UI drawing: Mixer, Playlist, Channel Rack, playing and scrolling
LYNX.AppImage --menu-entry on|off             Linux AppImage: add to / remove from the applications menu

./scripts/build-windows-zig.sh      # produces build-win/LYNX.exe

Needs Zig 0.14.1 in ~/opt/zig-x86_64-linux-0.14.1 and JUCE 8.0.4 in ~/opt/juce-8.0.4 (or set ZIG and JUCE_DIR). JUCE 8 does not officially support MinGW; the script works around the differences (see cmake/mingw/ and src/platform/MingwFixes.cpp).

Requires Visual Studio 2022 Build Tools ("Desktop development with C++"), CMake ≥ 3.22 and Git.

cmake -B build -G "Visual Studio 17 2022" -A x64
cmake --build build --config Release

Ubuntu 24.04 dependencies:

sudo apt install build-essential cmake ninja-build pkg-config libasound2-dev libjack-jackd2-dev libx11-dev \
  libxrandr-dev libxinerama-dev libxcursor-dev libxext-dev libxcomposite-dev libfreetype-dev libfontconfig1-dev libgl-dev

cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build

Needs the Xcode command line tools (xcode-select --install), CMake and Ninja (e.g. brew install cmake ninja).

cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64"
cmake --build build

CMAKE_OSX_ARCHITECTURES="arm64;x86_64" produces a universal app; leave it out to build for the current Mac only.

./scripts/build-local.sh ["folder with .flp files"]

More than a million checks, including parsing the 165 .flp projects that ship with FL Studio 2026 when that folder is given. It also builds build-local/flpdump (dumps a .flp) and build-local/renderwav.

• Lock-free audio: the UI edits a copy of the song and publishes an immutable snapshot to the audio thread.
• Chunked rendering: every note lands on its exact sample; mixer tracks are processed in parallel layers.
• Isolated plugins: plugin scanning always runs in separate processes; optionally the plugins themselves do too (a plugin that hangs goes silent and LYNX SHARE keeps playing).
