When beat matching,this view helps align the downbeatsof the two tracks. The markers arematched up when the two tracks arebeat matched.example: The following is ademonstration of using the visual aidsto help beat match. In this example,the track that is playing is on the leftdeck, and the track to be mixed in ison the right deck.1. Start the track playing on the right deck. Aftera few seconds, blue peaks appear in the TempoMatching display.2. Adjust the pitch of the right turntable until theblue peaks sit under the orange peaks in theTempo Matching display. Once they are aligned,the two tracks have the same tempo.3. Next align the markers in the Beat Matchingdisplay. Watch the color of the items passing byin the Main Waveform display. Remember that akick or bass drum will be red in color, and a snaredrum will be green or blue. This technique will byno means guarantee perfect mixes, but may helpto speed up the process of beat matching.maIn ScReenOVeRVIeWVIRtuaL decKThe Virtual Deck showseverything about thespeed and position ofa track.
