01 · Why SANDYNE

Six reasons to try it.

No account, no trial timer, nothing to unlock — here's what actually makes it worth the download.

01

It's free.

Not a trial, not a stripped-down edition. No account, no subscription, no locked features, no ads. Download it and it's yours.

02

You can learn it in an afternoon.

Most music software assumes you already know music software. SANDYNE is built so a first-timer can finish a song on day one — and so it keeps up once you know what you're doing.

03

It's a pleasure to look at.

A calm, considered interface where everything on screen earns its place. Nothing buried in menus, nothing shouting for attention.

04

Everything's already included.

Thirteen instruments and thirty-four effects, plus recording, mixing, stem separation and export. Nothing to buy before you can finish a track.

05

It's fast and light.

Opens in seconds, stays responsive while you work, and leaves your CPU headroom for the music. Native code, no web wrapper.

06

It's small, and it's moving.

Made by one person who reads every bug report. New features land every few weeks — see what just shipped.

02 · Demo

See it in action.

A short look at the app working — building a beat, adding sounds, and putting a song together. No talking, just the app.

03 · Editors

Three editors, one timeline.

Notes, audio recordings, and drum patterns all live on the same timeline. Double-click any clip to open the right editor for it.

SANDYNE Piano roll editor: violet notes on C5, G5, C6 and F4 laid out across four bars beside a vertical piano keyboard, a toolbar with a chord mode menu, 1/4 snap, and Quantize, Stretch, Arp, Ghost and Singer buttons, and a Note velocity strip along the bottom.
Note editor

Write and edit notes.

Draw notes on a piano-style grid, choose how loud each one is, and let the editor highlight the right scale. Type with your computer keyboard if you don't have a piano controller.

SANDYNE Sample editor showing a stereo waveform in magenta with a highlighted selection, and the Sample Ops panel on the right holding Playtime and Pitch knobs and Cut, Trim, Copy, Paste, Fade In, Fade Out, Maximize, Denoise, Scale, Stretch Proj. BPM, Reverse and Convert to mono buttons.
Audio editor

Work with recordings.

Browse and preview audio files, drag them onto the timeline, then trim, fade, or loop. You can even split a recording into separate parts — like pulling vocals out of a song — onto their own tracks.

SANDYNE Drum editor with an 808 kit loaded and a "Latin 808" pattern: rows for Kick, Snare, Rimshot, Clap, Closed Hat, Open Hat, toms, cymbals, Cowbell, congas, Maracas and Claves, each with a note assignment and pitch, volume and pan knobs plus mute and solo, and steps filled in across the grid in blue, magenta and violet.
Drum editor

Make drum patterns.

Tap out drum patterns on a grid. Choose how loud each hit is and where it sits in the speakers. Combine beats with melodies, recordings, and the rest of your song.

04 · Rework audio

Take a recording apart.

Point SANDYNE at any audio file — a finished song, a voice memo, a loop you found — and pull it apart into pieces you can actually edit. It all runs on your own machine, with nothing to buy and nothing uploaded anywhere.

SANDYNE "Extract Stems" dialog: "Choose stems to extract — stem separation will render separate WAV files for the selected stems", with Vocals, Drums, Bass and Instruments all ticked, a Quality menu set to Fast, a note reading "Model already downloaded - no extra download needed", and Extract and Cancel buttons.
Stem separation

Split a song into its parts.

Drop in a mixed track and tick what you want out of it — vocals, drums, bass, instruments — and each one lands as its own WAV. Remix it, sample it, or mute the vocal and practise over the top.

SANDYNE "Create a pianoroll track" dialog: a Material menu set to "Drums (kick, snare, cymbals)" with the note "Balanced detection for most drum material", a Sensitivity menu set to Normal, a Create menu set to "AnalogDrums track", and Convert and Cancel buttons.
Audio to MIDI

Turn a recording into notes.

Hum a melody, play a chord progression, or tap out a beat. Tell SANDYNE what it's listening to — a full mix, vocals and leads, bass, percussion or a drum kit — pick which instrument should play the result, and convert. You get an editable part you can fix, requantise, or rewrite from scratch.

SANDYNE Pitch editor: a vocal recording with each detected note drawn as a labelled block (F4, A4, G4, B4, B5, G5) over the waveform, the sung pitch traced as a line inside each one, ten notes selected in pink, and a side panel with key and scale menus, Natural / Tight / Hard presets, Strength, Drift, Vibrato and Retune knobs, and Apply pitch correction and Reset changes buttons.
Pitch editor

Nudge a note back in tune.

Every note in a take is detected and laid over the waveform, with the sung pitch traced inside it — so you can see the flat note, the scoop into it, and the wobble at the end before you touch anything. Select the notes you want and leave the rest alone.

Take the Natural, Tight or Hard preset, or set strength, drift, vibrato and retune time by hand. Pick a key and scale and it corrects to that — or skip correcting altogether and turn the performance into a MIDI track instead.

05 · Racks

Chain anything, in any order.

Every track has a rack — a left-to-right chain you fill with MIDI effects, an instrument, and audio effects. Drag modules around to change the order. The signal flows through whatever you put there.

Rack · Pad · 6 modules MIDI → INSTRUMENT → AUDIO FX → MASTER
SANDYNE Rack panel: a horizontal chain of modules — Arp arpeggiator, Random MIDI effect, Syna synthesizer, Aero reverb, Compressor, and Master bus — each shown as a vertical module with knobs and controls.
06 · Built-in instruments

Thirteen instruments. Start playing now.

Open the browser, drag one onto a track, play. You get real recordings of a piano, drums and orchestra, plus a set of synths for original sounds — so you have something to play from minute one.

Shape, place, color, watch.

Built-in effects for making your tracks louder, warmer, more spacious, more distorted, or just easier to see. Use them on any track, or on the whole mix.

08 · Web interface

Control it from any device on your network.

SANDYNE includes a built-in web interface. Open the page in any browser — phone, tablet, another laptop — and you can watch what's happening, record notes and audio, and tweak the mix without sitting in front of the main computer.

http://studio.local:58371 LIVE · 9 TRACKS · 39 CLIPS
SANDYNE web interface showing the TRACKS view in a browser: 9 colored instrument tracks (BG Pad, mellow arp, arp, SampleTank, two basses, BM-VICE, Synth pad, Repro-5) with MIDI clips laid out along the timeline, transport controls and port number at the top.

Watch from anywhere

See what's playing, scroll the timeline, switch between tracks, mixer, and visualizer views — all in a browser tab.

Record without touching the keyboard

Record notes and audio from your phone or tablet. Useful for capturing ideas while you're holding an instrument.

Mix from the couch

Mute, solo, volume and pan all work remotely. Set a balance from across the room without leaving where you're listening.

→ The web interface is limited compared to the desktop app — it's for monitoring and capture, not deep editing.

09 · Mixing

Two ways to mix.

SANDYNE has the classic vertical-fader mixer most music software uses, and a 2D Visual Mixer where every track becomes a marker on a stage. Use either, or both — they edit the same mix.

Visual Mixer · 9 tracks GHOSTS · ON · LUFS −10.5 INTEGR
SANDYNE Visual Mixer panel: nine numbered pucks placed across a 2D stage with horizontal pan and vertical volume axes, motion ghost-trails radiating from each puck, master strip and loudness meters on the right.
↳ Mix by feel, not by number. Drag left/right for pan, up/down for volume. The trailing colors show where each track has been moving over time — a quick way to see how busy a mix is.
10 · Movement

Two ways to make
your song breathe.

A mix sounds more alive when things move over time. SANDYNE gives you two ways to do that: recording a move once and replaying it, or letting a knob wobble on its own. Every knob shows both at a glance.

A · Record a move

Move a knob, play it back.

Press REC, touch any control, and perform the move. From now on, the same change happens automatically every time you play the song — in Touch, Latch or Write mode, with curves if you want to shape it by hand afterwards. Works on any knob — built-in or in your own plug-ins.

CUTOFF · TRACK AUTOMATION
B · Make it move on its own

Give a knob a life of its own.

Set a knob where you want it, then attach a slow sweep, a beat-following pulse, or your own pattern. The value you set stays put while the sound moves around it. Great for filter sweeps, wobbles, and anything that needs to feel less robotic.

CUTOFF · LFO MODULATION · 0.4 Hz
CUTOFF 5040 SAVED 6320 LIVE · Hz
On every knob

The inner ring shows the value you set — what gets saved with your song. The outer ring shows the value you actually hear, including any movement. You can see both at a glance.

11 · Use your own plug-ins

Bring the plug-ins you
already own.

Plug-ins are extra instruments and effects you can install into music apps. If you already have some in the VST3 or CLAP format — or LV2 on Linux — drop them in and they work just like the built-in ones. AU support is coming soon on Mac. Save your song and everything comes back exactly as you left it.

  • Use plug-in instruments and effects anywhere in your mix
  • Record changes to any knob and replay them
  • Make any knob move on its own over time
  • Find all your installed plug-ins in one browser
12 · Save your song

Save it as a file. Or several.

Save the whole song, just a section, or each track on its own (handy for sharing with someone who'll mix or master it). Pros can also drive everything from a terminal.
