Replacer is a specialized tool designed to substitute drum and percussive sounds with alternative samples seamlessly. It employs a band-pass filter to isolate the specific frequency range of the original sound, allowing precise identification for replacement. When the peak amplitude within this range is detected, the plugin triggers the selected sample, ensuring accurate timing and response.

Users can load 16 or 24-bit PCM Wave files at any sample rate, providing flexibility in the types of samples used for replacement. The interface includes visual and audio monitoring options, enabling detailed observation of the triggering process. Additional controls such as sample start and end points, pitch adjustments, and an envelope for shaping the sample's attack, decay, and release offer creative shaping possibilities.

Replacer also features multiple sample layers and dynamics controls that help replicate the feel of the original performance. Accent and smoothness settings allow for dynamic variation, closely matching the nuances of the initial percussive hit. This combination of precision filtering and expressive sample control makes it an effective solution for enhancing or transforming drum tracks.
