We build the sampler tools we wished existed.
Hliuma LLC is a company built by musicians, for musicians — we make apps for people who make music. Our first product, Xampler, takes your recordings and builds you an instrument you can play, straight in the format your hardware actually uses. Your audio stays yours: no one sees it, it never reaches us, everything is processed on your machine. No install, no hassle.
Three principles. No compromises.
Your samples, not ours.
Pitch detection runs locally on your CPU. The in-house loop finder streams raw PCM for one note at a time to a Germany-based server, finds the loop in memory, returns coordinates only. Nothing is saved on our servers.
Built for the engines that ship inside real keyboards.
Per-channel stereo loop points. SF2 stereo pairs that don't collapse on PA-series arrangers. KMP / KSF with byte-accurate chunk layout. Tested against the spec, not against a heuristic.
From a folder of WAVs to a playable instrument in five minutes.
Drag, detect, audition, export. No round-trip to a desktop DAW, no plugin install. You export straight into the formats you already use (SFZ, SF2, Korg KMP/KSF) — you're never locked into a proprietary format.
The toolset, plainly.
- AI pitch detection
Ensemble of four algorithms — three classical, one neural. Robust across piano, strings, brass, guitar.
- 5+3 loop algorithms
Five next-generation finders for multisamples, three for drum slices. Engineered in-house, not stock library.
- Crossfade editor
Draggable region with zero-crossing snap. Per-channel on stereo so L and R stay independent.
- Hardware export
SFZ, SF2, KMP/KSF, WAV with SMPL loop chunks. Names follow each format's convention.
- MIDI controller preview
Plug a USB controller, play the keyboard before export. Works in Chrome and Edge.
- Non-destructive .hli
Project file keeps your samples intact. Toggle normalize, re-run loop finder, re-export forever.
