time signatures with phasor~

September 24, 2009 | 12:39 pm

I cant find anything about this in the mailing list.
Im looking for a example how to handle the time signatures with a audio phase from phasor~. Maybe a combination with count~ and rate~?

every help will be much appreciated!!

phasor responds to the time code for the transport object. take a look at that.

alternatively you could convert beats to Hz.

thanks for the example. but i cant understand where is the goal with the BPM to HZ conversion to get time signatures like 3/4 or 3/12.

im looking for a way to handle time signatures outside of transport.

thanks a lot!!

hi RapidRaja,

thanks a lot for the clear example.
Actually I don’t need a counter so it works perfect for me, but I will try it and post it here if I can get something interesting.

Thanks a lot guys, very kind!

If you can convert the length of one beat into Hz, then you can scale that value to include multiple beats. For example, if you are in a 3/4 measure, divide Hz by 3 (or multiply the BPM value by 3), and you’ll get a phasor ramping from 0-1 over the course of a measure. If you want the phasor to ramp through beats 1-3, then multiply the output of the phasor by [*~ 3.].

This also allows for much stranger subdivisions than transport permits. Scale the value of the BPM by 7/5, or 8/3, or any other peculiar fraction, for interesting (if not always musically successful) results. Perhaps reset all phasors’ phase to 0 every X amount of beats for a syncing mechanism between these unusual subdivisions.
