a friend sent me an mp3 which i opened and used the acw to sort out the chords and tempo.

the chords i have corrected in RB and i think the bar lines are about right.

but the tempo varies a little throughout the song. i can't find the manual reference to aligning to a click track - can anyone help?

but.......before i do that if i have click track to the best approximation of the real time what happens if i align the track?

does it align the mp3 to the track - stretching and condensing the timing as necessary - just like quantising midi?

currently using a drum grid edited tambourine hit ( the only rhythm the track needs) some of the hits are marginally off beats one and three.

if the align to click track won't align the bars to the click track is it best to start again and try to get every bar line exactly right with the acw or can i re-edit it? or will i have to simply move every midi event manually to align the hits correctly?

i assume RB has created a tempo map which will govern midi events if the bar lines are absolutely right

online and electronic manuals aren't as easy to search and scan as hard copies
