Tempo and Timeline

Digital audio recordings differ from MIDI sequences in a very
important respect. Changing the tempo of your song will not
change the rate of playback of an audio recording, as it would a
MIDI sequence. If you do change the tempo of the song after
recording audio, the starting bar positions of the regions will
change, but they will play for exactly the same amount of time
as they did when originally recorded. This is because the rate of
playback is determined by the sample rate of the audio hard-
ware, not the internal clock in the computer.
For this reason, you should carefully choose the tempo when
you start to make an audio recording. A change is not easy to
make after the fact.
