Poly Tempo

I would to have one instrument track play in one tempo and another instrument track play in another tempo simultaneously. How do I achieve this?



If you change a Tempo, all MIDI data will follow the tempo change. So the only one way is to Bounce (Render in Place) it to audio and then make sure the audio event is not in the Musical Mode (then it would follow the tempo change too) and the track is in the Linear Mode.
