Pocket groovebox · Android · Closed beta

Press. Hear. Make.

A pocket groovebox — sampler, sequencer, synth.
Built for beatmakers who want to make, not configure.

SALTO SAMPLER running on Pixel and iPhone
48kHz sample rate · Float32 stereo · ~10ms latency · 32-voice polyphony · No IAP · Android first

Three tools, one surface.

Sampler, 16-step sequencer, and synthesizer — on the same 4×4 grid. Switch modes, not apps.

Sampler main screen
01 · Sampler

Load a WAV. Tap AUTO. Sixteen slices.

Drop a loop, slice it in one tap, spread it across the pads. Real WAV decoder. Choke groups, velocity, soft-clipped master.

Sequencer screen
02 · Sequencer

16 steps. Pads become beats.

Same 4×4 grid turns into a step sequencer. Swing, per-pattern BPM, sample-accurate timing. No separate app for patterns.

Synth screen
03 · Synth

A synth on the same pads.

Built-in polyphonic synth voice. Per-voice LFO, tempo-sync optional. MACRO A/B routes to any parameter you care about.

Flip it.

Salto is a somersault. A flip in the air.

A flip of a sample is what beatmakers do. The name, the logo, the product — same promise. Load, flip, make.

  1. 01

    Load

    Drop any WAV from your phone. PCM16 or Float32. Stereo is kept.

  2. 02

    Flip

    Tap AUTO for spectral-flux slicing, or drag markers by hand. Preview with a tap.

  3. 03

    Make

    Play the pads. Record a 16-step pattern. Tweak with MACRO A/B. Export when ready.

A taste.

Two knobs. Whole groove.

In SALTO, MACRO A and MACRO B are your two hands on the sound. Map them to any parameter — filter, pitch, swing, reverb — and tweak the whole kit in one gesture. No menus, no sub-screens. That's the instrument, not the app.

Tap to start — sound on. Drag the macros.

SALTOv1.6.0 32-voice · DEMO

Instrument, not app.

"Every UI decision is in service of the next sound happening faster."

SALTO is designed to be played, not configured. Pads trigger on press-down, not release. The audio engine is C++ on Google Oboe, in exclusive mode, so you feel the hit — not the software. No in-app purchases, no onboarding carousel, no subscription.

Questions.

When does SALTO ship?

1.0 lands on Google Play in 2026. Sign up above — you'll get one email when it's live.

Android only?

For now, yes. Android first because Oboe gives us the tightest latency. iOS is on the roadmap — no date yet. We'll tell you honestly when it's real.

How is it different from Koala Sampler or BandLab?

Koala is a great sampler — different tool, different workflow. SALTO is a dedicated groovebox: sampler, 16-step sequencer, and built-in synth on the same 4×4 grid, running on our own native C++ audio engine. ~10ms latency, 32-voice polyphony, no IAP, no subscription. Some people will want both — they answer different questions.

Is there a paid version?

No in-app purchases. No subscription. If we charge for SALTO, it'll be one up-front price on the Play Store and that's it.

What devices do you support?

Android 11+ with Oboe-compatible audio. ~10ms round-trip on Pixel 6+ and similar. Older phones will be slower — we'll tell you honestly in the store listing.

Can I export my beats?

Yes. Render the current pattern to a WAV you can share or drop into a DAW.
