Jitter to tempo


    Feb 04 2010 | 2:11 pm
    Hi, Im quite competent when using audio in max msp but i was wondering if i could get osme help on the jitter side of things basically im wanting to make a simple patch where i can load a sound file into a buffer then have some video or animation react in some way ? just wondering how i go about matching tmepo objects or metro objects to some kind of jit.matrix or some way of controlling parameters via tempo ?

      probably the best way is to match the rendering or movie metro/qmetro rates to your audio's BPM. Try:
      bpm--> !/ 60. (note the exclamation mark for inverse) * 1000. --> equals milliseconds for your metro.
      "tap tempo" is not difficult with [timer] and taking an average of (say) 4 taps. Lots of examples out there, but you can probably make your own in no time.

      also look at the following objects: jit.scanoffset, jit.gl.graph.
