When importing an acapella vocal or instrument recording (track) and attempting to add rhythm and music to it, I find that the automatic "beat mapping" feature is not very good. The flaw seems to be that it only uses one measure of the music and is not accurate when the tempo that it finds is extended to the entire song.
So, if I were to do this manually, maybe by intentionally changing the tempo of each sound-track, then how can I do this in the "Acid-Music-Studio-11", program?
I know you can change the tempo of the entire group by double-clicking on the BPM number that is shown, but how do you change the tempo (BPM) of one track, say the drums, to synchronize with the rhythm of vocal singing or any other sound-track?
Note: I know that if the acapella vocals, guitar, or anything else had a metronome or "click-track" then it would be easy to "beat-map" but usually there is none and the producer has to graph out the music on the screen and find the best synchronization. Most tutorials that I have found recommend using Ableton Live to do this, or pro tools, but I do not want to attempt to "tap" the rhythm because I don't feel that it's accurate enough to rely on my finger and the keypad.
