01 · 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.

02 · Visual Mixer

Mix by feel, not by number.

Each track becomes a marker on a 2D stage. Drag left or right to change where it sits in the speakers. Drag up or down to change how loud it is. Mix with your hand instead of typing numbers.

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. — ↳ From a real song. The trailing colors show where each track has been moving over time — a quick way to see how busy a mix is.

Try it yourself

Drag any dot below. Left and right is pan. Up and down is volume. The meters on the side respond live.

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 showing 19 bars of a layered melodic part — green G/G2 notes with blue chord tones (D3, F3, A#3, D4, D#4) — over a scale-aware keyboard guide, with a Note Velocity strip below.

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 with a stereo waveform showing five bars of percussive audio, ruler bar with beat markers, and a Sample Ops panel on the right with cut, trim, fade, normalize, denoise, scale, stretch, and zero-crossing controls.

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 Beats editor showing a 16-step pattern across multiple drum lanes (Kick, Snare, Closed Hat, Cowbell, Hi Conga, Mid Conga, Claves and more) with per-step values in cyan and violet.

Beat 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 · Built-in instruments

Eleven 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.

Synth

Terrain

A synth that builds its sound by tracing a path across a moving 3D landscape. Great for evolving, otherworldly tones.

Synth

Syna

A classic synth for leads, pads, basses and arpeggios.

Synth · atmosphere

Ambient

Drum machine

Analog Drums

Punchy electronic drum sounds — kick, snare, tom, hi-hat, cymbals — generated from scratch instead of recordings.

Synth · voice

Robot

06 · 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. Works on any knob — built-in or in your own plug-ins.

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.

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.

07 · 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 format, drop them in — they work just like the built-in ones. Save your song and everything comes back exactly as you left it.

08 · 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.
