Then someone posted a link to this ingenious little app in the Modul8 forums and I have been using it ever since. It picks up the beat after a few seconds and it’s pretty accurate – as long as there is a steady discernible beat to the music of course.
You try it out in demo mode (and click away a dialog box every twenty minutes). It’s an independent app so apart from Modul8 it ought to work with any VJ app that supports midi clock.
1. First you go to the Waveclock preferences and select your microphone or line-in for the input. And some midi channel for the output – IAC Driver for instance.
2. Then in Modul8 or your other VJ app you go to preferences and confirm that IAC Driver is activated as a midi input.
3. Then (in Modul8) you activate the BPM modul and click ‘use midi clock’.
