Assuming you want a pulse in non-signal domain, you could use disis_phasor~ (see http://l2ork.music.vt.edu/main/?page_id=56 for download links) which outputs a bang every time ramp is crossed. This is only accurate to the nearest sigvs size (by default 64 bytes) as there is no guarantee that you will get a msg interrupt exactly at the time ramp has crossed.

Subject: [PD] Rewriting a unified phasor / metro object for reading tables

Hi Lists(s),

I'm rewriting phasor~ and unifying it with metro so that a pulse is generated from the boundaries of each ramp - so that bars of music can be read using tabread~ objects with a sample-accurate metro.

I'm sure someone will say this can already be done, but it has to be dropped into the Ninja Jamm patch, so there isn't really time to rewrite the rest of the patch.

I don't fully understand the way phasor~ wraps, but I have the object firing out bar numbers correctly. I'm putting clocks in for 16ths and 24ths of the beat, initiated on each wrap. I need to minimise CPU, so what I want to know is this:

Does phasor~ always start from 0 and go to 1, i.e. is there always a signal value of 0 at the start of the ramp and a signal value of 1 at the end? As I write this, my common sense tells me it should be "yes" but I want to make sure. I suppose I should just try it really...

Cheers,

Ed
