Pay per credit. Nothing expires.
No subscriptions, no monthly bill. Multisamples cost 1 credit per channel (mono 1, stereo 2) and drum loops a flat 5 credits per loop. You pay once, when a WAV is analysed — loop editing, slicing, export and project saves are unlimited and free.

The DEMO runs the full editor with pre-loaded samples, right in your browser. No account, no card, no download.
Open the demoOne credit per channel. That's the whole model.
No metering, no surprises. A credit is spent only when a fresh recording is analysed — and a failed analysis is refunded automatically.
1 credit per channel — a mono sample costs 1, a stereo sample 2, because pitch and loop work spans both sides.
A flat 5 credits per loop, however many slices it splits into. One analysis, one charge.
Loop tweaks, slicing, EQ, every export format and reloading .hli / .hld projects all cost nothing. You pay once, per fresh WAV.
If an analysis fails — a corrupt file, an unreadable channel — the credits return to your balance automatically.
The whole toolset. No tier locked behind a paywall.
Credits only buy analysis volume. Every feature below is on every plan — and free forever once a sample is in the editor.
- AI pitch detection — an ensemble of four algorithms — three classical analysers and a neural model — maps each note to the right key, accurate to a few cents
- 5 + 3 loop algorithms — five in-house loop finders for multisamples and three for drum slices, each with its own crossfade curve — engineered in-house, not a library import
- Loop editor with crossfade visualization — draggable crossfade region with zero-crossing snap and live preview, independent on each stereo channel
- Real-time preview — audition every note live with your mouse, a MIDI controller, or your QWERTY keyboard
- Auto note-split — drop one WAV containing many notes — Xampler cuts them apart, detects pitch and maps each one automatically, no manual slicing
- Drum slicer — onset detection, BPM and time-signature estimation, per-slice gain, fade, reverse and quantize
- Per-sample EQ, normalize & fade — 4-band parametric EQ, peak-normalize and fade-in per note — baked into the sample on export
- Hardware-grade export — SFZ, SF2 (correct stereo-pair samples), WAV + SMPL loop chunk and Korg KMP / KSF — no conversion tools in the middle
- Save / load .hli & .hld projects — free and unlimited — reload, re-loop and re-export forever; pitch detection pays only once
- Interactive HELP in 9 languages — an in-editor guide with annotated hotspots on every control
- Runs in your browser — no install, no plugin, no desktop app — just open it in Chrome, Edge or Brave
- Your audio stays on your machine — files never reach our disks; pitch detection runs locally — GDPR, servers in Germany
- No subscriptions — credits never expire and nothing auto-renews
Top up when you actually have work to do. Nothing auto-renews and nothing lapses — the credits you buy today still work next year.
Open it in a Chromium browser and start. No desktop app to license, no dongle, no version you have to keep up to date.
Pitch detection runs on your own CPU; we only bill the single server step that finds your loops. Editing, slicing and every export after that are free.
The money questions, answered.
Do credits expire?
No. Credits never expire. Buy a pack once and use it whenever you like — today, next month, or next year.
What exactly uses a credit?
Only a fresh analysis. Multisamples cost 1 credit per channel (a mono sample is 1, a stereo sample 2). Drum loops cost a flat 5 credits per loop, no matter how many slices. Editing, slicing, export and reloading saved projects are all free.
Is there a free trial?
Yes. Every new account starts with 5 free credits. And the live DEMO runs the full editor with pre-loaded samples right in your browser, with no login at all.
Do I pay again to edit or re-export?
No. The charge happens once, at analysis. After that you can re-run loop detection, re-slice, adjust EQ and export to every format as many times as you want — including reloading .hli / .hld projects — at no extra cost.
What happens if an analysis fails?
The credits are returned to your balance automatically, up to what that file was charged. A corrupt file or an unreadable channel never costs you anything.
How do I pay?
Through our secure checkout. Pick a package, pay by card, and the credits land in your account instantly.
Are there subscriptions or hidden fees?
None. No monthly bill, no auto-renewal, no per-export surcharge. You buy a credit pack and that is the entire transaction.
Can I buy more credits later?
Anytime. New packs stack on top of your existing balance and — like everything else — never expire.
