UndoLooper - Build Verse/Chorus Live with Unlimited Undo

Welcome to Undolooper:

Welcome! If you’re a live looping artist, you already know the absolute magic of building a track from scratch right in front of an audience. But if your goal is to perform dynamic, full-length songs, you've probably run into the exact same wall I did. I’ve gigged with almost every heavy-hitter on the market—the Boss RC-505, Electro-Harmonix 45000, Pigtronix Infinity, TC-Helicon VoiceLive. They are incredible machines, but they share one massive limitation that restricts your ability to truly perform:

They only give you one undo.

Why That Stops Your Show Cold Picture your set:
You lay down a driving acoustic rhythm. You tap out some percussive body slaps. You layer a deep bassline. You add lush, ambient volume swells. The crowd is feeling it, and the sound is massive. But what happens when it’s time for the next verse? To make the song breathe, you need to drop the energy back down to something quiet and intimate. With a standard pedal, you are stuck—you can only strip away the very last thing you played. You’re trapped in a static, repeating wall of sound, and your arrangement has nowhere left to go.

Real songs build up, break down, and evolve. They aren't just a repeating block of noise. A New Way to Perform I realized standard hardware simply wasn't built for the way we actually want to perform. So, I built something different. Welcome to Undolooper—designed to give you the freedom to build, deconstruct, and reshape your layers on the fly, so you can finally perform your songs exactly how you hear them.

Introducing UndoLooper: The Looper That Thinks Like an Arranger

UndoLooper is a software plugin (VST3) and standalone app that gives you unlimited undo and redo. It bridges the gap between traditional hardware looping pedals and modern studio software.

Because it processes audio instantly without CPU dropouts or latency, you aren't just layering audio anymore. You are using Undo and Redo as performance tools to build song structures.

Imagine you are playing a 90s rock medley. You build up your full arrangement—rhythm, percussion, bass, and lead. That’s your massive Chorus.

Now, hit undo, undo, undo. Strip it back to just the raw acoustic guitar and kick drum. That’s your Verse.

Perform the verse, then hit redo, redo, redo to instantly trigger those layers back and explode into the massive Chorus. Verse to chorus and back again. Breakdown to drop. Sparse to full. Your entire performance history becomes your live arrangement.

The Problem With "Live" Hardware Pedals

Here is what else will frustrate you about standard loopers, and how UndoLooper fixes it:

• The "Tap Dance" (Long-Presses): Want to stop a hardware pedal? Long-press. Want to clear it? Long-press and pray you held it the right amount of time. When you're playing live, you need instant response. UndoLooper has zero long-presses for performance. One press = one action. The only long-press is to clear the loop intentionally, so your song flow is never interrupted.
• Harsh Stops: Most loopers just CUT your audio when you hit stop. It’s jarring, unmusical, and sounds amateur. UndoLooper features an "Echo Stop." When you stop, it adds a carefully manicured, musical echo tail that fades naturally. No more harsh cuts. Just smooth, professional endings.
• Amnesia: You spend 20 minutes building the perfect loop arrangement, and when you shut down the pedal? Gone. Forever.

The Revolution: .undoloop Files

UndoLooper saves everything—your uncompressed stereo audio AND your complete undo/redo history—into a single .undoloop file.

Think about what this means for a live guitarist:

• Gig Prep: Build a setlist of pre-layered loops ready to perform and break down live.
• Learn: Download .undoloop files from pros and study exactly how they arrange their guitars, undo by undo.
• Collaborate: Share your performance with another musician who can undo and redo through YOUR layers.

A looper isn’t just an instrument anymore—it’s a community waiting to happen.

Your Performance Shortcuts

• "Back 5": Need to drop the energy fast? Hit "Back 5" and instantly peel back five layers at once. Perfect for jumping straight back to your verse arrangement without tap-dancing on a pedal.
• "Bring It Back": Instantly restores your most recent massive loop state. Go from a solo acoustic breakdown back to your 10-layer finale with one click.

P.S. - I use UndoLooper with my own guitar every single day. It's not vaporware. It's the looper I needed to exist, so I coded it. Now it's yours. — Ryan
