I would like to make a DJ software like the Traktor (Native Instrument) by Max.

I have just built a playback system using groove~ and waveform~, but facing a problem what I could not.

1, Change a playback speed in real time while playing a tune.

2, Show up the BPM as soon as you replace a audio file onto buffer~.

4, Auto tempo sync mode for different audio files

If someone genius don't mind share patches or references (links), please drop your comment here.
