---------------------------------------------------------------Matching audio loops to the song tempo
If you have a brilliant loop (e.g. a drum loop) in WAV format
but the loop tempo diverges from the song tempo by a massive
30 bpm, you can make the tempos converge without using time
stretching, which would normally force you to stick to one
song tempo as well as strain the sound quality of your loop.
You can import your loops in WAV format directly into Cubase
and work with so-called Match Points. Import your desired WAV
file into an audio track and double click on the part to access
the audio editor. Select the waveform with a mouseclick and
then create the M-Points ("Do" - "Get M-Points"). This opens
the "Get M-Points" menu, in which you can enter the maximum
number of events per second as well as attack.
Experiment with different settings to find out which are best
suited to your loop material. Click on "Process" to
calculate the M-Points.
Now click on "Snip at M-Points". You can see that the loop
has been cut into different segments, which you can mute,
move, copy and rearrange onto different tracks using
copy/paste. You can then assign varying effects to these
segments.
Leave the audio editor and set the desired tempo in the
transport bar by double clicking on the bpm counter and
entering the new tempo.
Tempo changes of up to +/- 30 bpm can processed without any
Problem. Exceeding these limits can affect the sound quality,
depending on the suitability of the loop material.
The advantage of this method over ReCycle Version 1.7 is that
you can work in stereo and yet not lose any of your sound
quality.
