I'm not a DJ, but I like music, preferably different scratches. I even tried it at an old soviet turntable once.

And once, while strolling up and down with an MP3-player and twitching the volume up and down, I thought that it would be so deck to have two little turntables in my pockets. So you can make scratches while listening to some songs or radio.

That's how I came to the idea of "Scrachy"
