Tactile12000 is a QuickTime-based 3D simulation of a DJ setup, consisting of two virtual turntables and a mixer. It allows you to cross-fade, back-spin, and speed up and slow down music--including full-length WAV and MP3 files--on your computer. It allows you to mix songs, and it can automatically cross-fade between songs stored in your MP3 playlist. Version 2.1 has a new interface, audio-cueing capabilities, pitch bending, improved controls, bug fixes, and more.
