resetting cycle~
is there any way to send cycle~ back to the beginning of it's cycle with a message? i know you can set the phase, but this can only alter the play position relative to its current position... i need to bang a load of different ones to synchronise their phase.
thanks.
just realised maybe i could send it a set tablename message. i'll try it
nope this doesn't seem to work
Sending a zero to the phase inlet of a cycle~ object will always "reset" it back to 0. Phase is not relative to the current value being output from the cycle~ object, it's absolute. So, sending a float to the phase input will always result in the same output.

i just checked this and it doesnt seem to be true - if i send it a 0, and its phase is already at 0, then it has no effect. if its phase is at (for example) 0.2, and then i send it a 0, it moves 0.2 of a cycle backwards (relative). i'm using the right inlet as a signal inlet by the way.
Hmm, you're right. My bad.
In any case, try this:
Use a cycle~ object with no argument for initial frequency, and use a phasor~ object connected to the phase inlet of the cycle~. Make the frequency of the phasor~ object equal to the frequency of the sine wave you want to get out of the cycle~. The phasor~ will drive the cycle~ object at the appropriate frequency, with the added bonus that you can send a 0 to the phase inlet of the phasor~, and it actually will reset the cycle~ object the way you want it to.
heh, i'm being awkward here, but i don't think i can do that either, because the reason i'm using cycle~ in the first place rather than phasor is so that i can have a signal phase input (i need to control phase in the normal relative way and for it to be glitch free when it moves, but occasionally i will need to send a message to re-synchronise everything as well)
cheers for the suggestions anyway. maybe if there is a way to slide phasor's phase around at signal rate then i could do that instead of using cycle~ at all?

i've found that turning dsp off then on again has the desired effect. but i can't believe there's no other way to do this..
try this patch: to reset the phase you have to set it to zero AND send a bang to the third inlet.

Hmm well you want the best of both worlds, don't you? ;)
I suppose you can still use a phasor~ to drive the cycle~ object, doing the absolute phase "resets" from the phasor~ phase inlet. Then, you could add a delay~ object in between the phasor~ and the cycle~ to do your relative phase adjustment. You'd need to do a little bit of math to figure out how many samples you'd need to delay the phasor~ by in order to shift its phase by the desired amount.
Getting a little bit complicated now, but I can't think of any other way to get both relative and absolute phase adjustment at the same time.
ah yes that will work, thanks very much
the patch above works great.
thanks again
