Scratch audio/video

Hello

I want to make an app to be able to record audio and video and scratch it. video it’s easy with queue texture, but im having problems doing it with audio. ive tried many vst but none of them seems to do the job. relofter http://andreas.smartelectronix.com/index.php?nav=9&p=5&kat=0

was the closest one, but im having problems when i try to connect the play pin to control it instead of using the vst GUI.

there’s no other way to record audio just with vvvv nodes instead of vst ?
