So I have been working on a patch that would allow a DJ Hero controller to act similarly to an actual turntable. Currently I can do a couple of different functions such as controlling volume, start stop, etc. but I have not been able to figure out how to make an authentic sounding scratch in relation to the movements of the turntable. If anyone knows how to make this type of sound I would appreciate your method.

The patch is attached if necessary for reference or if anyone is interested in it. Sorry if it is messy I have been learning PD as I wrote it, and I am a newbie.

I have and I am using that patch as the basis but I am looking for a different way to create a more authentic sound.

yes Maelstorm that was exactly what I was looking for. Thank you!
