I made this in Plogue Bidule, so I'm sure it would be easy in PD. In Bidule, it worked but only as a proof of concept, because the streaming soundfiles were streaming out of RAM, not off of disc, as would be needed in reality.

Basically you just need variable playback speed of an audiofile, and a couple of buttons to bump the sound file forward or backward. Getting the bump button tweaked to move exactly the right amount is key, since you can't put your hand on the turntable to speed up or slow down slightly.

In order to cue properly, you need multiple outs on your soundcard, unless you cue with the right and send sound from the left (not the greatest solution in my opinion).
