        Could work. Would be better if it sent over the BPM via OSC or something?

        It's funny because the mixer they used on stage last time at the temple was a Pionner with MIDI out so that could in theory give us BPM data. But not every DJ used that mixer.

          This simple QC plugin seems to work in Quartz Composer: http://kineme.net/forum/Programming/CoGeBeatDetektor, however, in Isadora it does not output any values. Has anybody gotten it to work in Isadora?

              @bruper: It is not a plugin, it's a qc patch, which uses the plugin, which can be obtained from the link I posted.

                  This is the one I found a while back:

                  Looks ideal.

                      SO... I want to make a bunch of short loops that I can sync to bpm.

                      Did a quick demo patch but wondered if anyone has better suggestions of how to patch it up. (no vid file attached but it was a 90 frame simple 1920 animation)
                      Also a screen grab.
                      The tap in this example would/could be replaced with what ever BPM analysis we go for.
                      TY!!!

                        One approach I have used before is to produce clips to 100bpm

                        Then I dynamically adjusted the playback speed according to the realtime bpm. 
                        eg: if the realtime bpm was 120, playback speed would be 1.2
