EDIT SAMPLE /
BPM MATCH
Pressing BPM MATCH will show something like this screen display:
This is another derivative of the timestretch algorithm. The parameters are almost identical to the
TIMESTRETCH function with the addition of the SOURCE TEMPO parameter.
The BPM MATCH function allows you to stretch a sample to a new tempo. It works like this:
You have a sample that you know is 123 BPM however, the track you are working on is 127 BPM.
To match the tempo of the sample to your track, set 123.00 BPM in the SOURCE TEMPO field (i.e.
the tempo of the original sample). Now set a value of 127 BPM in the NEW TEMPO field (i.e. the
tempo you want it to be to match the track you are working on). Choose a preset that approximates
the type of sample you are trying to process and press MATCH NEW BPM. You will see the usual
“Processing sample” progress display followed by the PLAY/KEEP ORIGINAL/NEW/BOTH and
RENAME prompt. Using the PLAY NEW and PLAY ORIGINAL, you will hear the tempo change.
You can decide whether you want to keep it or not.
Of course, the whole BPM MATCH process relies on you knowing the tempo of the sample you are
trying the process and the tempo of the track you are attempting to match it to.
As with the TIMESTRETCH and PITCH SHIFT pages, a series of presets optimised for certain
sounds is provided. The ADJUST parameter is available via the PRESET parameter’s WINDOW
function.
NOTE: When using BPM MATCH on a sample that has loops, you may find that the processed
versions loop points are slightly disrupted and exhibit clicks. To overcome this, visit the LOOP
page and try AUTO FIND and/or a CROSSFADE - this should restore the loop farily easily.
However, a bit of work may be necessary to get a perfect loop again.
