Beat-Recognition-System:
Another extraordinary feature of the SIRIUS is its BEAT-RECONGITION-System. This function allows
you to synchronise the Sirius to an external audio signal.
You can use the BEAT-RECOGNITION-System to create a remix of a Vinyl-record or CD with the
help of additional tracks of the SIRIUS. During a live-gig you can also, in the DJ-setup, fade-in the
SIRIUS using the velocity of the last song.
The tempo of a song is expressed in bpm ( eats- er- inute). A value of 120 bpm, in the case of a
continuous quarter-note kick-drum, would mean that the kick-drum would beat 120 times a minute.
The SIRIUS reacts with its-BEAT-RECOGNITION-system to the average frequency of a kick-drum. It
analyses not only the quarter note in an audio track but works with a 16th grid. This way you can
also synchronise audio-tracks where not necessarily every quarter beat is covered with a kick-drum.
The BEAT-RECOGINTION-SYSTEM is constantly searching for/receiving the incoming audio-signal
which allows it to recognise the smallest tempo-changes and then adjust the tempo of the SIRIUS to
it. If during a rhythm pause there is no kick-drum for a long period the Sirius will continue with the
tempo it has calculated. In most cases the Sirius will continue even after a pause in the exact syn-
chronous tempo.
In order to analyse the audio material, the source of the audio (eg. a CD player) will have to be con-
nected to the Sirius. The included Goose-neck microphone is unsuitable for this purpose. In order to
control this system to the maximum use the Analyse or Carrier-input of the Sirius.
The following diagram shows you the connections for the control of the BEAT-RECOGNITON-
system:
