Xtractpler

The Ultimate Multi-Velocity Audio Sampler and Sound Library Exporter

Xtractpler automates recording, slicing, and processing multi-velocity samples from any audio or MIDI source—with a next-gen engine and a clearer five-step workflow.

What's New in v3.5.5

A major leap in audio quality, capture speed, and everyday usability—without losing the workflow you already know.

Next-Gen Audio Engine

An all-new audio engine lifts capture quality, sonic fidelity, and slicing precision to a new level—so transients snap into place and your multis sound exactly as intended.

Blazing Fast Capture Methods

New Internal (VST3/AU) capture with Offline Audio Render unlocks a dramatic jump in render speed. Plus Live Capture walks you through the process with manual and automatic modes.

Expanded Format Support

Export finished audio as FLAC and OGG alongside WAV and MP3—choose the format that fits your archive, DAW, and delivery targets.

Multi-Note Range Entry

Skip the tedious manual setup. Instantly capture an entire keyboard by entering a note range like C1..C8 or 36..108 in a single grid row. Xtractpler auto-expands and names every slice for you.

Advanced Sample Mapping

Generate automatic mapping files natively for SFZ, Decent Sampler, Ableton Sampler (.adv), Bitwig, and FL Studio FPC, so your libraries map cleanly into every major workstation.

Redesigned 5-Step Workflow

The GUI is rebuilt around five focused tabs—Configure, Plug-ins, Capture, Review, and Export—so you always know where you are in the pipeline.

Enhanced Feedback & Stability

Real-time VU meters (stereo/mono), accurate progress bars, an integrated error console, and a richer waveform view help you judge levels, timing between transients, and grid tuning at a glance.

Massive Under-the-Hood Optimization

Deep stability fixes, stronger performance, and leaner memory and CPU use—while staying fully compatible with .xcfg projects from v3.0.

Pro-Grade Grid UX

Major upgrades to the configuration grid: flawless row deletion, lightning-fast Tab navigation for data entry, and strict focus trapping for a frustration-free workflow.

Live Capture & a Redesigned Interface

Guided Live Capture keeps you in control whether you prefer hands-on passes or automated runs—ideal for hardware, live instruments, and reactive sessions.

The new five-tab workflow mirrors how producers actually work: Configure, Plug-ins, Capture, Review, and Export. The same refined UI runs natively on macOS, Windows, and Linux—here’s Guided Live Capture on macOS.

Xtractpler Guided Live Capture on macOS

Next-Gen Audio Engine

The engine is rebuilt for cleaner capture, higher fidelity, and more accurate transient slicing.

  • Sharper slicing — Samples align tightly to transients so velocity layers stack predictably in your DAW or sampler.
  • Richer monitoring — Stereo/mono VU meters and an upgraded waveform view make level and timing decisions obvious before you commit.
  • Stable under load — Lower CPU and memory pressure during long sessions, with a dedicated error console when something needs your attention.
Xtractpler Internal Capture tab on Windows with VST3 offline render

Internal Capture (VST3 / AU) & Offline Render

When your sound lives inside plug-ins, Internal (VST3/AU) capture renders through your chain without relying on real-time playback headroom.

  • Offline Audio Render — The host-style offline pass slashes capture time versus traditional real-time recording, especially on dense instrument stacks.
  • Repeatable results — Same grid, same chain: ideal for batching velocities and round-robins with minimal drift.
  • Cross-platform — VST3 on Windows and Linux; VST3 and AU on macOS, all from the same tabbed workflow.
Advanced Waveform Review and Grid Alignment

Advanced Waveform Visualization

Master your transients with surgical precision. The high-fidelity waveform display in the Review tab allows for sample-accurate inspection.

  • Visual Verification — Verify the exact timing between transients to ensure your grid parameters perfectly match the captured audio.
  • Dynamic Adaptation — Use visual feedback to fine-tune threshold levels, fade-outs, and durations before committing to the final export.
  • Quality Control — Easily spot double hits, unexpected artifacts, or level inconsistencies across different velocity layers.
Chromatic Note and Range Input in Configuration Grid

Chromatic Note & Range Input

Sampling tonal instruments is now faster and more intuitive with native support for Musical Notation and Note Ranges.

  • Intelligent Expansion — Enter a range like 'C1..C5' and Xtractpler will automatically generate the full chromatic map, saving minutes of manual data entry.
  • Standard Notation — Work the way you think: use MIDI numbers or standard names (e.g., 'D#2') directly in the configuration grid.
  • Seamless Workflow — Perfect for creating multisampled instruments, ensuring every note in the range is captured with consistent velocity layers and settings.

Export & Mapping

Finish the job in one place: audio files plus sampler-ready mapping where you need it.

  • FLAC & OGG — Join WAV and MP3 for archival, streaming-friendly, or engine-specific pipelines without leaving Xtractpler.
  • SFZ — Generate mapping files automatically so velocity layers and round-robins load cleanly in SFZ-compatible players.
  • Decent Sampler — Export companion presets tailored to Decent Sampler's layout, cutting manual key-range and velocity wiring.
  • Ableton (.adv & .adg), Bitwig, FL Studio FPC — Native presets for the most popular DAWs, generated automatically alongside your audio files.

Coming Soon: Pro Extensions for Akai MPC, Roland SPD-SX PRO, Elektron, and Studio One.
