# sync-ing a phasor~

this is probably a wood for the trees thing, but how do I start a phasor~ from 0. every time I play a note or whatever ? the sync input of the saw~ is not to be found on the phasor~, but that’s what I need.

or am I being dense ?

thanks,

stuart

phasor~’s second inlet?

i hang my head in shame BUT

can anyone explain the difference, if there is one, between the phase input of phasor~ and the sync input of saw~, and while we’re at it, the difference between phase and duty cycle ?

‘d be much obliged

phase is a particular appearance or state in a regularly recurring cycle of changes

duty cycle is the high portion in the cycle of a pulse wave

it takes all of us

the tri~ and rect~ objects both have ‘duty cycle’ inputs, and all three of
‘saw’, ‘rect’, and ‘tri’ have a sync input. It’s important to keep aware of
this distinction.

duty cycle for ‘rect~’ changes the relative amount of time that the pulse is
up versus down. for ‘tri~’, at 0.5, you get an isoceles triangle wave, and
as you change the duty cycle, the relative amount of time that the wave
spends going up versus down changes, so that at a duty cycle 0 or 1 the wave
is a saw wave, and between 0. see the manual entry on triangle~.

as far as the difference between the phase input on phasor and the sync
input on saw~, one practical (if perhaps obvious) difference is that phasor~
takes a float-only input versus the signal-only input of saw~. taken from
saw~ entry in manual: “When the control signal crosses from below 0.5 to
above 0.5, the oscillator resets itself.” This is equivalent to sending a
’0′ message to phasor – when phasor receives ’0′, it resets itself.

So in some ways, the ‘phase’ inlet of phasor~ is more flexible, but it is
subject to command processing timing restrictions, hence can’t be used to
