i guess my question is if i can have a perform function not in a tilde external. i got the headtracker to work in a tilde external, and i'm outputting floats instead of a signal. i'm actually not doing any signal processing in it, i just want the continuous grabbing of headtracker data.

I don't think you can do really continuous message output (that would be a signal out, although that also isn't continuous (ADC/DAC). Ths closes I could imagine is somthing like the [metro] internal object and similar objects, that keep their own timer.

Hey Scott,
I've made a couple of externals that "act" continuous but I've always just set up the methods so that they are called by a bang to the object from the outside...
This way you can control how often you want to poll the HW (or whatever) from PD... Or did you need faster than 5ms updates? Seems a little over-kill for a head-tracker....

I use an internal clock in my parapin external, and I can change the polling delay. I prefered this to polling from an external metro object, because it uses less objects and probably less resources. It really is easy to add an internal clock with flext.
