Hosi Auto Loop Detector for REAPER DAW

 

Speed up your sample chopping, loop creation, and instrument design workflow! Auto Loop Detector is a powerful Lua script for REAPER that automatically scans your audio and MIDI items to find perfect loop points based on RMS energy or Peak transients.

Whether you are extracting drum breaks, slicing vocals, or building massive sample packs, this tool will save you hours of manual editing.

There are two versions available: the Standard Version (100% Free) and the PRO Version (Supporter Exclusive) packed with advanced sound design and export features.

🟢 STANDARD VERSION (Free)

A robust and precise tool for everyday editing and slicing.

Core Features:

• Dual Detection Modes: Choose between RMS (perfect for pads, vocals, and long textures) or Transient/Peak (ideal for drums and sharp percussion) with 2ms-5ms high precision.

• Smart Processing: Automatically split, trim, strip silence, and apply auto-fades to prevent clicks.

• Peak Normalization: Auto-scale volume to your target dB for consistent sample levels.

• Intelligent Naming & Coloring: Batch rename sections automatically and append project BPM and Key (e.g., Loop_1_120bpm_C#m). Match track colors or randomize them for easy visual organization.

• Workflow Integration: Built-in transport bar to seamlessly preview and navigate between detected loops without leaving the UI.

• Custom Presets: Save and load your favorite detection settings for different instruments.

💎 PRO VERSION (Supporter Exclusive)

Take your sound design to the next level. The PRO version includes everything in the Standard version, plus powerful tools to instantly turn your slices into playable instruments and professional sample packs.

Exclusive PRO Features:

• Advanced Instrument Export: Automatically generate ready-to-play DecentSampler (.dspreset) and SFZ (.sfz) instrument patches right from your REAPER timeline.

• Auto-Velocity Mapping: Automatically measure the RMS of your slices and stack them into dynamic, multi-layered velocity zones on a single MIDI key.

• Slice to Sampler (Map to MIDI): Instantly map your chopped loops into REAPER's native ReaSamplomatic5000 (RS5k). It automatically creates a new track, loads the samples, and maps them chromatically starting from C4.

• Generate Variations: With one click, generate 5 creative variations of your selected loops on a new track: Reverse, Half-time, Double-time, Octave Up (+12), and Octave Down (-12).

• HTML Preview Generator: Automatically generates a sleek, interactive webpage (index.html) so you or your users can audition your newly exported sample pack in any browser.

• 🥚 Plus a fun, hidden Easter Egg for sound mangling!
