T1 The BPM goes way off when using the search
button on my high tech CD mixer.
Some high tech CD mixers have a cueing feature which
allows you to cue precisely to an exact spot in the music so
you can slam mix. The only problem is that this mode repeats
the first beat of the music at a rate which is unrelated to the
actual BPM of the music. As a result, the BPM goes off track.
The best way to avoid this is to restart the music after a
search, make sure the Beatkeeper is resynced to the music
and then press the Cue button on the CD player. The
Beatkeeper will remember the BPM and track the music
once it starts.
T2 The Beatkeeper doesn't resync to the
downbeat of the music when the music restarts.
Either the downbeat isn't strong enough to be detected,
or the music was started well before a strong downbeat.
You can easily resync to the downbeat by tapping the Beat
Assist button once with the beat. Alternatively you can cue
the music to a strong downbeat so that the Beatkeeper
starts on this downbeat.
T4 Either the BPM display is blank, or it is
noticeably off.
This is common at the beginnings of songs where the beat
is not well defined. To sync simply tap the Beat Assist button
two or more consecutive times on the downbeat. The Sync
Lock LED turns on automatically, indicating that the
Beatkeeper is now tracking the beat of the music.
T5 The BPM display is correct, but the beat LED
isn't flashing on the downbeats of the music.
If this happens tap the Sync Lock button (turning the Sync
Lock LED on) and tap the Beat Assist button once to make
the Beatkeeper track the downbeat. You can also use this to
force the Beatkeeper to track an offbeat for more advanced
mixing.
Alternatively you may sync manually by tapping the Beat
Assist button 2 or more times on the beat.
T6 The Beats per minute number seems to jump
all over the place.
The Beatkeeper is analyzing different sections of the
music to find the BPM. If there is a temporary suspension of
a distinct beat or if the rhythm is too complex, this number
may not follow the actual BPM.
a ) You can wait for a passage of music with a steady beat
for a more accurate BPM indication.
b ) Hit the Sync Lock button once the red beat LED starts
following the beat
or c ) Tap the Beat Assist button at least twice along with
the music beat.
Either method (b or c) will cause the Sync Lock LED to turn
and lock on, indicating that the Beatkeeper is now tracking
the music.
T7 It takes too long for the Beatkeeper to find
the beat on its own.
To speed up the BPM detection process, tap the Beat
Assist button at least twice. At this point, the Beatkeeper will
turn on the Sync Lock LED, immediately providing a BPM
estimate, while resynchronizing to the beat you tapped.
