Written in VB6 and uses DirectX8. This program I wrote is the closest thing to a real turntable. It uses real physics, and uses a 4th Order Runge Kutta integrator to increase accuracy. I still need to add sound though (related to This project which has scratching capabilities), plus a mixer and another turntable, not to mention allow you to control the tone arm, and allow the platter to rotate as well, which, all in all, wil allow you to really DJ without you having to dishing out the cash for a set of your own. But for now, enjoy what I have so far!
