OneTrick URCHIN simulates drums being recorded, played back, and chopped. It's powered by a combination of spectral and physical modeling which is run through effects and filters designed to give a saturated vintage feel. You can control the "playback speed" that the drums were "sampled" at on the fly with the pitch wheel, which might just be a first. We've built in a preset browser with editing, tagging, and searching, and included 20 factory presets to get you started.
The source code is also available for you to inspect, adapt and learn from under the GPLv3.
