Xtractpler offers an accessible solution for capturing audio samples from any VST, AAX, AU plugin, MIDI-capable synths, acoustic instruments, or vocals via microphone input. It automates the process of recording triggered MIDI notes at multiple velocity levels and slices the captured audio into multi-velocity WAV files. This functionality enables musicians and producers to create custom sample libraries compatible with various samplers, loopers, and electronic drum modules, all without the need for a digital audio workstation.

The software supports multiple capture modes tailored to different audio durations, including short drum hits, longer sustained sounds, live acoustic performances, and speech recordings. Users benefit from features such as automatic trimming, normalization, configurable fade-outs, and customizable velocity curves. It also includes a Round Robin sample feature to add natural variation to repeated notes. Xtractpler works on Windows and Mac systems, though Mac users require third-party audio routing tools, and Windows users need to enable certain MIDI and audio routing components for full functionality.

Xtractpler streamlines sample extraction by handling all technical aspects like MIDI note management and audio formatting, allowing creators to focus on sound design and library building. It facilitates the creation of new sound banks by capturing audio from diverse sources, including live instruments and external audio inputs. This tool is also effective for processing spoken word material by reducing silences for podcast or video applications. Its ability to unify and resample layered drum kits makes it especially useful for maximizing the memory efficiency of electronic drum modules.
