Please remind me how Isadora works with audio units/quartz composer timing wise?

  • So if I have a quartz composer patch running in Isadora, how often can I expect data to flow either way?

    Say my Isadora patch is running at 30fps and I have a QC actor which is running a stopwatch within it, will the stopwatch update 30 times a second or is the timing independent from Isadora?
    And just to check, any data will be fed in/passed out of the quartz actor at 30fps (or whatever the frame rate is)? 
    With audio units presumably data is passed out (sample rate/buffer size) times a second - all audio happens at this rate within Isadora? but control data is passed in at Isadora's frame rate?
    Are any of these assumptions about right?
