I have no problem with it whatsoever, its always worked a charm for me, and it was advised to me when i started patching, so i always did!

But, i never asked why. So…why?

Thanks

Because it is part of the signal network, it also is locked to all other objects in the same patch, and so there is no long-term drift in timing, relative to other msp objects in the patch

but if you do a search you’ll find more detailed explanations

phasor is also short for ‘phase-vector’:
http://en.wikipedia.org/wiki/Phasor

http://en.wikipedia.org/wiki/Phasor_measurement_unit

the object ‘phasor~’ in max and pd is based on a similar idea of traversing a vector(of samples) that keeps a running count of phase(from 0 to 1) with sample-accuracy. by definition, it’s highly suited for tight synchronization.

Will look more into it

Thanks guys!

I want to be able to stop, start and reset this patch without loosing synchronisation. Could anyone briefly look at my patch and tell me if I am approaching this correctly? The button at the top of the patch resets everything when pressed.
