          So I am away in Italy at the mo so can't access a lot of my gear but thought I'd try out 'Beat Monitor' its a little app. a bit old fashioned but seems to work pretty well. But system hungry.

          @Skulpture what d'you think about running the BPM analysis for Glasto on an iPad next to the main servers? that way we have a visual number from this app on the iPad all the time and can just punch in the numbers as they need to update? I played for about an hour yesterday and everything I want to sync worked fine. Or do you have a more 'automatic' suggestion? BTW I want to draw the schematic for Glastonbury next week so email me anting you want it to have in.

              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
