DM 1635
2 Channel Mixing
After you feel comfortable syncing up the
Beatkeeper, you're ready to mix. Mixing with the
Beatkeeper has three parts: syncing to the
music (which you've done), aligning the tempos,
and aligning the beats. Once these three things
are done, you will have a perfect mix. No more guessing,
tapping, or embarrassing fades.
Choose another music selection and start it on your
right channel. Sync up the first song as described in
the last section. With the first selection synced (Sync
Lock LED illuminated), sync up the right channel
the same way you set up the left.
As the second Sync Lock LED illuminates, a
new dimension of DJing begins: V I S U A L
MIXING.
The bar graphs on the top of the
Beatkeeper have now been activated and are
updating automatically.
NOTE: In order to perform a mix which is tracked by
the Beatkeeper, both channels MUST be synced. This
is indicated by the yellow Sync Lock LED being lit for
both inputs.
In order to create the perfect mix, your goal
is to keep both bar graphs as close to
centered (green or yellow) as possible.
First, align the top graph, the Tempo Difference
Graph. This graph indicates how close the two BPMs are
to each other. If they are exactly the same tempo, the
green LED in the middle will light up. If one song is faster
than the other, the bar graph will shift towards the faster
song. If the Tempo Difference graph is not
centered, adjust the speed of one of the
inputs using the pitch control. For example, if the
Tempo Difference graph has a red LED illuminated
closer to the right channel of the Beatkeeper, the right
channel is faster than the left channel, either slow down
the right channel, or speed up the left channel.
If the opposite is true, the Tempo Difference Graph has
a red LED illuminated on the left channel, indicating the
song on the left channel is faster than that the right
channel, either slow down the left channel, or speed up
the right channel.The second step involves the bottom
graph, the Beat Offset Graph. This graph indicates how
close the individual beats are. Both BPMs may be the
same but the beats may not be in sync. This is often
described as the “ping-pong” effect. If the beats are
matched, the green LED in the middle lights up. If the
beats of one input are earlier than beats of the other
input, the Beat Offset Graph will shift toward the song
with the earlier beats.
To align the Beat Offset Graph when using
CD Players, adjust the appropriate pitch bend.
If you are using turntables, hold or apply
pressure to the record/turntable and then
release to “shift” the beat.
If the Beat Offset graph is shifted toward the right
channel either use the minus (“-”) pitch bend for the right
channel CD player (with vinyl, apply pressure to slow the
turntable) or use the plus (“+”) pitch bend for the left
channel CD player (with vinyl push the turntable ahead).
Intuitively, if either bar graph is shifted towards a
channel, this indicates that the song on that channel is
“ahead” of the other one. Either the tempo is faster (top
graph), or the beats come sooner (bottom graph).
When both bar graphs are in the green you
are ready to perform your mix!
Don’t forget you can always resync to the beat, if it ever
shifts off, by tapping the Beat Assist button.
If the beats start to drift, you'll be able to easily adjust
the music before your audience can hear it. No other
beat counter or automatic mixer can give you the power
to make a more accurate mix!
NOTE: The Beat Offset bar graph either indicates beat-
to-beat offset, or beat-to-halfbeat offset, whichever is
closer. This allows the DJ the option of mixing on the
beat or on the half beat.
