"Rhythmic Convolutions" is a set of 200 Impulse Responses designed to add motion and timbre transformation to rhythmic loops, drum machines, drums and instruments with a percussive quality.
Impulse Responses are audio files (WAV 48KHz / 24bit .wav) that can be loaded inside compatible convolution plugins and hardware that accept user's Impulse Responses. Convology XT is a great option and it’s free: Convology XT.
Some DAWs like Ableton Live already include a convolution reverb.
"Rhythmic Convolutions 2" is also available, expanding the concept in new directions: gum.co/FFSRC2
