How do you automate the bpm in ableton?

could some one please help me how to automate the bpm in ableton?? i just cant figure it out. thanks

you mean make a track change tempo during it playing?

in arrange view you would just expand the master channel and adjut using the tempo envelope - just click the drop down where it says mixer

thats spot on m8. thank you.

see im making a cd in ableton, mixing all the tracks together. if i have automated the cd from 147bpm to 149bpm, does that mean i then have to warp the tracks to 149 bpm??

No it doesnt, it automatically ajusts, aslong as they are warped you will be fine.
