I am just starting out this dj app thing and yours was the most realistic reacting turntable, especially when you let it go off a scratch, you gotta let it go real life style, all I would add is another turn table for two tracks, and since I liked it here's the one nobody thought of have a third table where the recording is being recorded. Then put a small wave editor program in. I wasn't to chop up 100 songs right now but all the apps are either to complicated or to cheap, use your start with all my ideas and you will thank Jesus when your do !
