Channel Selection
When your mixer is first turned on, the channels
selected will be 1 & 2 respectively. If you wish to track
the beat of another channel, tap on the channel select
button until the desired input is reached.
N O T E : The Beatkeeper will track the source that is
selected with the channel toggle switch.
Syncing Your Beatkeeper
When learning how to use the Beatkeeper, choose
some dance music with a hard, steady beat.
Start the music for left channel of your
B e a t k e e p e r . When the Beatkeeper has located the
beat, the BPM display will illuminate with the music's
Beats Per Minute.
You'll notice a flashing Green LED every time the
Beatkeeper detects a rhythm defining instrument. The
Beatkeeper will soon flash a Red LED on every beat, the
same way you would tap your foot to the beat of the
music. The Beatkeeper will display a BPM which will
update every five seconds while scanning. As long as
the beat is well-defined, the BPM number will equal the
beats per minute of the song being played. Once you
see the Red beat LED flashing with the beat of
the music, press the respective Sync Lock
b u t t o n , and the Sync Lock LED will illuminate.
Activating the Sync Lock tells the Beatkeeper to stop
scanning the music for a different BPM and to start
tracking the beat changes of the current BPM as you
adjust the pitch of the music. This function is manual to
ensure that the Beatkeeper is right on the beat. O n c e
the Sync Lock LED is on, the Beatkeeper
tracks the beats of the music and updates the
BPM display on every beat.
To unlock, simply tap the Sync Lock button once and
the Beatkeeper is back in BPM scanning mode.
After syncing an audio input, try speeding up and
slowing down the music. You'll notice that the Red beat
LED will continue to flash on the downbeat, and the BPM
number will adjust itself to match the tempo of the music.
This indicates that the Beatkeeper is successfully
tracking the beat and will continue to do so throughout
your mix. If you stop the music, you will notice the Beat
LED will go solid and the BPM number will remain in
memory. Once the music is restarted, the Beatkeeper
will remember the last tracked rhythm pattern and pick up
on the beat right away.
P L A Y the music, O B S E R V E the beat match, and
PRESS the Sync Lock Button. That's it. If you can
do that twice, you can mix with the Beatkeeper.
Beat Assist
The Beatkeeper is foolproof. The Beatkeeper can
track any music up to 199 beats per minute. The unit,
however, is set to automatically track tempos between
80-150BPM. Of course, not all music is within this
range, you may need to track the high tempos of
Meringue or Salsa, or the low tempos of R&B slow jams
or Reggae. Let's face it, not all music has hard, steady
beats either, and sometimes you just need the music
set up yesterday . For these occasions, we have the
Beat Assist Button.
If the Beatkeeper is having trouble
matching the beat to the flashing Red Beat
LED, or if you need to sync up immediately,
tap the Beat Assist button 2-8 times as you
hear the beat, the same way you would tap
your feet to the music. Pressing the Beat Assist
Button more than once aligns the Beatkeeper to your
taps. Notice that the Sync Lock LED automatically
illuminates, signifying that the Beatkeeper is now locked
in with the beat. Simply put, if the Beatkeeper isn't on
track, or you're in a real hurry, you need to press a
button twice instead of once.
If the Beatkeeper is synced to the correct
BPM, but is aligned to the music's offbeat, tap
the Beat Assist button with the beat of the
music just once, and you will have brought the
Beatkeeper back in sync.
Two 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:
VISUAL 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.
