Using one ezdac at a time?

    Jan 23 2014 | 10:35 am
    I've built a patch using six different 'ezdac' buttons (as required) but I can't figure out how to only use one at a time as at the moment, they all turn on. I found an example of how to do this on the internet, but it hasn't worked. Any ideas?
    I'm using Max 6.1.6.

      ezdac~ is controlling a global state. That state affects every single MSP object open in Max at the time. It's generally not best practice to have more than one ezdac~ in a patch at all, because it just makes you think you can control them individually, which you can't.
      What you can do is send the ezdac~ (or plain-vanilla dac~ or adc~) a 'startwindow' message. That way DSP is only turned on for the objects in the current window (and its sub-patches). That's as fine-grained as the control gets. Otherwise you have to use poly~ or other techniques to only activate part of a patch.
      This is all explained in the tutorials. I hate to bring those up, but it if you've misunderstood this one, very fundamental aspect of MSP, there are probably other things you're making false assumptions about. Time well spent.
