MATCHING THE BEATS PER MINUTE (BPM)
Beat matching is the act of finding the BPM’s (beats per a minute) of two different music sources, and
matching them together. After you have matched the BPM’s you use your mixer to fade the volume
in and out of one song to the next without music interruption while retaining the same beat. Use
the PITCH SLIDER (17) to match the BPM’s of one PRO SCRATCH 1™ to that of another PRO
SCRATCH 1™ or other music source. Use your mixer's crossfader to blend them in to each other
seamlessly. This is a function that may take some practice.
