Overview

An instrument that turns your samples into motion.

Drop in up to eight sounds, choose how fast it chops and how it moves, and the engine builds a sequenced pattern that jumps between your slots in time with your track. Add chaos for surprising variation that's always reproducible: it's seed-based, so any result you like comes back exactly. Then take control by hand, pinning steps to specific samples, silencing others, and saving the moments you love as instant-recall scenes. It's built for fast, happy-accident sound design that still bends to your intent.

Whether you're chopping a vocal, mangling a break, or sequencing one-shots into something new, Chop Machine gets you from a static sample to a living pattern in seconds, and gives you the controls to shape it exactly the way you want.

See & hear it

Watch it chop.

The full Chop Machine window: eight named sample slots down either side, the sequence display and motion engine in the centre, and the scene pads along the bottom. — Eight slots, the sequence display and the motion engine, all on one screen.

Four sample slots showing different settings: level, pitch, attack, decay, playback mode and reverse, with one slot muted. — Every slot gets its own level, pitch, attack, decay, playback mode and reverse.

The sequence display with chaos at 100, showing a jagged pattern across all eight slot colours, above the rate, motion, articulation and chaos controls. — Chaos at 100, and it is seeded, so a pattern you like comes back note for note.

The Fill dialog with a sample loaded and its waveform shown, ready to load it into all eight named slots at once, with an auto-chop option. — Fill loads one sound across several slots at once, optionally auto-chopping it.

What you can do

Built to move, made to control.

Sequence eight samples at once

Eight slots, up to 20 seconds of audio each, with per-slot pitch (±36 semitones) and per-slot reverse.

Set the motion

Chop from 1/4 down to 1/32 (including triplets), pick a motion shape (Ramp, Triangle, Sine, Random, and more), and dial how far it travels with Amplitude.

Dial in chaos

Chaos is seeded and pseudo-random, not a coin toss. Re-roll for a new seed until a pattern grabs you, then keep that seed and it recalls note-for-note every time.

Refine by hand

Pin any step to a specific sample, or click to silence it. The algorithm gets you started; you get the final say.

Save scenes

Capture the entire engine state to a scene pad for instant recall during a session or a performance.

Export the loop

Drag the current loop straight out to your DAW or desktop as a 24-bit WAV at your project's tempo and sample rate.

FAQ

Good to know.

Is there a trial?

Yes. A free 5-day demo key unlocks the full instrument. Give an email address at checkout and the key arrives in your inbox; there is nothing to pay and no card required.

Which formats and platforms are supported?

VST3 and Audio Unit plugins plus a Standalone app, on macOS (Intel + Apple Silicon) and Windows.

Windows warned me about the installer. Is something wrong?

No. Chop Machine is code-signed with a verified certificate issued to Tendergreen Studio LLC, and you can see that name on the installer before you run it. What you are seeing is Microsoft SmartScreen, which also weighs how many times a file has been downloaded. A brand new release has no download history yet, so it can be flagged purely for being new. That reputation builds on its own over the first weeks.

If your browser blocks the download, choose to keep it, then on the warning screen pick More info and Run anyway. Check the publisher reads Tendergreen Studio LLC first. If it does not, do not run it, and tell us.

The macOS installer is signed and notarized by Apple, so it should open without a fuss.

Is there an iPhone / iPad version?

Not yet. Chop Machine launches on macOS and Windows. An iPhone and iPad version is in development. It will be a separate App Store purchase when it arrives, since Apple requires apps to be sold there.

Do I need to be online to use it?

No. Activation is a one-time offline product key: no account, no internet connection required.

Can I move it between computers?

Yes. Your license covers all the computers you personally own. Just activate with your key on each.

Will my patches stay intact if I send them to someone?

Yes. A saved .chop patch embeds the audio, so it's fully self-contained and portable.
