Hi,

I want to create a chase effect on the beat of the music.

Anyone a idea ?

Maybe a taping the beat on a button on the WD and then create key-points on a seq in PB ?

Yup

1- create a fader (lets call him fader1)
2-Create an Audio Processor Node (input node)
3-Create a Fader Node (output node)

Using the Audio Processor node settings isolate the bass drum (filter mids and highs and all lows below the bass drum if there are any)

Connect the Audio Processor input Node to the Fader output Node

In the Fader Node assign the Audio Processor Volume

Now the bass drum controls the fader output, if the fader is assigned to the opacity of a video device it will then fade the video in and out in tune with the beat.

NOW, make it a serious script using a Range Node (filter node) and Damping Node (filter node) so that the volume output affects the whole range of the value the fader is assigned to and damp it so the modulation feels natural and fluid.

Alternativelly you can assign the Audio Processor Node to a DMX output rather than a fader.
Alternativelly you can Assign the Audio Processor Low output to the Fader node or DMX output node and have less settings to take care of or to use the same Audio processor node for several faders (using mid, high, low, volume). It will make sense when you try stuff out.

A little while ago I created a Widget that has a manual "Tap" for Beats Per Minute - An audio processor to find the BPM, and a way to manually enter in the number if you know what it is...

Maybe you can use this Widget as a starting point and change it to your needs?
