I am synthesizing a bell tone that has some slight modulation on the fundamental. I have amp modulated the tone with a cycle~ object. The only problem is that when I trigger the bell tone using a bang the modulated cycle could be anywhere in it's waveform. Therefore the hits are not consistent. How do I reset the phase of the cycle on each bang?

Thanks for the reply. Sending a 0. into the phase input doesn't seem to work for me. I have tried a float into sig~ and into phase as well and it still doesn't reset.

You can use a phasor~ to drive the phase inlet of cycle~ and then reset phasor with a [button] > [ trigger 0]. Then you just send the desired frequency to phasor~ instead of cycle~.

Maybe you could post a small patch with what you want to do

Excellent. The phasor reset works. Thanks for the help guys.

Thanx Tim Llyod, helped here to get phase distorted bass drums clean.

Question: How to avoid clicks on a cycle~ when the phasor~ gets triggered again? Example patch:

in this solution I reset the phase of the oscillator in 1ms, then open the envelope over 5ms. It's simply a matter of event ordering, and seems to work fine; any residual transients occur only at around 100-200Hz, but are not envelope or phase-reset clicks:

Thank you very much, Brendan. Smart and simple.

this is my patch. with the hints in this thread it got better, but i still hear differences in each instance of my kick drum. why? anyway it seems a bit awkward in 2018 in such a refined environment as max msp to not have a simple way to reset the phase to zero degrees in oscillators.

What about this way? (hint: I just moved one cable)

See below (changes to your patch marked with red color). In your original patch the cycle~ object had attached two sources of frequency. Of course you can make your own object encapsulating desirable behaviour, and from that point on Max will have "simple way" of doing anything ;-).

EDIT: perfect!it now works and i finally understood! so the phasor not only resets the phase, but modulating fase sets the frequency too of the cycle~, correct? (thanks again)

thanks, checking it right now!!!

phasor ... drives the "playhead" inside the cycle wavetable (as soon as its signal is connected to the second inlet of cycle) - as opposed to a cycle object "running" on its own.

phasor starts exactly at 0. and ends exactly at 1. , where 0-1 describes the way once through the wavetable. 

(i guess it would be right to claim that technically the cycle object has a "phasor" built in, which is controlled by inlet #1)

you can modify the phasor output to play backwards or only the first half of the cycle object, or you can distort the linear path from 0. to 1., or, as requested here, to restart the playing from 0. controlled by a bang, which is, among things, required to sync two or more cycles.

thanks for your clear explanation! really useful!

Reset cycle~ Phase with bang?
