        I have just found this too:

        [http://showsync.info/index.php/tools/beattracker/](http://showsync.info/index.php/tools/beattracker/)
        _"Beattracker is a standalone beat tracker module that analyzes an incoming audio signal and accurately detects the tempo and the current beat position after feeding it an initial tempo by tapping. It outputs the tempo and beat information in various formats, such as MIDI clock, OSC and MA net."_

                  I´m trying a different approach: In Cubase I made a midi track with a short bass drum, tapped to my main Wave Track. I exported a midi and an audio file of this bass drum sync track: The idea was to start both tracks (audible track and inaudible sync track) with a keyboard watcher or enter scene trigger-the sync track should change after e.g. 8 beats -counter actor, some effect of the video. So now I have no idea what actor midi, audio, audio core, etc actor to use for the sync track, that triggers the counter and shoul be not audible. Its not about live capturing the audio. Any ideas?

                      The MIDI player in Isadora; actually plays a MIDI file; it doesn't send the note out. 

                      This is where Ableton is perfect for Live stuff as that will and the MIDI out and play music at the same time.
                      I will have a think about the best solution today for you.

                          Really what you need is something like Duration or Vezer

                          But these mostly deal with OSC (similar to MIDI in many ways really - in its simplest form they both send messages just via deferent methods/protocols)
                          Worth having a look anyway.

                            Duration is really worth a look.

                              It is indeed. I don't think you can drag a MIDI file into Duration though.

                              But, saying that, I would swap the MIDI for OSC if I am totally honest. 
                              It may be a bit more work but the workflow is much better and reliable.

                                  On my windows machine, I managed to send OSC data from duration to Isadora. cool. but how to import my sync (midi or audio) file into duration? Skulpure I think you´re right, that you cant  import a midi file in duration.

                                    I'd be tempted to create an OSC track in Duration with triggers on every beat. Scrap the MIDI file.

                                      Ok, on the mac it works, on two windows machines: one is crashing (duration) and the other can only open an older version of duration, where you cant import audio files.
                                      So Mac wins ;-)
                                      Thanx for the advice!
