Multiple Channel Mixing

One exciting feature of your Beatkeeper built into your mixer is the option to visually beat mix more than 2 sources at the same time. Once you have synced a channel of the Beatkeeper the unit will continue to track it even if you should decide to change channels. Up to all four channels can be in sync simultaneously. By selecting different channels you can cross-compare the mix of any 2 channels instantly.

In order do perform a 3-way mix you first will need to set up a 2-way mix as described in the previous section.

NOTE: Multiple source or “layer” mixes should be performed with a minimum of vocals otherwise the music will clash when mixed for a long period of time.

The next step will be to decide which input channel you would like to use as a reference for beat mixing. While your 2-way mix is ongoing change the channel, on the side you have not chosen as a reference, to the next song you plan to mix into. Now sync and mix this song like you did for the 2-way mix. After you have synced up the new song you should continue to check your original mix by switching between channels. When you have properly aligned the new song you are ready to perform a 3-way mix.

To perform a 4-way mix just do the same thing again.

Prepping For A Mix

You may also choose to prep the Beatkeeper for an actual mix. To prep the Beatkeeper, first match the two song's tempos by adjusting the pitch so that the Tempo Difference LED graph displays yellow or green LEDs. Next hit the Cue button of your CD player, or lift your record needle. The red “beat” LED will remain solid alerting you to which input is ready to start. When the music starts again, the Beatkeeper begins right on the beat and indicates how well the two songs are synced within seconds.

Syncing To Off Beats

Now if you really want to be fancy, you can actually use the Beatkeeper to sync to the off- beats. You can have two songs going “Boom - Cha - Boom - Cha”. Normally, you would sync the “Booms” of both songs (beat-to-beat mixing). But you can also sync the “Boom” of one song to the “Cha” of the other (beat-to-half beat mixing). The Beatkeeper’s Beat Offset graph will display whichever offset is smaller. This allows the DJ the flexibility to mix with the beat or the off-beat.

Beat mixing is a skill that must be practiced in order to be proficient at it. 3 and 4-way mixing can be a very difficult skill to master. Visual mixing with the Beatkeeper gives you the tools to help you do this, but nothing replaces practice.
