hello,

i recently discover the patch of maelstorm, phase-sync2.mmb.pd, it works very well and is very useful ! but i' ve got a problem, i don' t manage to make it work properly
under 1 hz. indeed if i choose a frequency of 0.8 for the master oscillo, the slave will
be false. maybe i make something wrong. here the patch.

thank you

It looks fine to me. When the master [phasor~] drops back to zero, the slave [phasor~] should also reset, and that's what's happening. As long as there's a reset in the slave at the same time the master resets, it's synced.

it' s strange...did you try with with the patch i uploaded, phaseSynchro.Quest.pd ?
i test it on an other computer and it' s the same. if i click on the message 0.8 the slave waveform begin to be wrong. we can see next two normal ramps cycles a little one and so on. here a snapshot of what happen under 1 hz.

That's how it is supposed to look. The end of the little ramp should happen right at the end of the master ramp. The little ramp occurs because the slave is supposed to reset at the end of the master ramp. In this case, the slave is resetting while in the middle of it's ramp.

You don't see that when the master is set to 1 Hz because it just lines up perfectly. The 2 Hz slave makes two ramps in exactly the same amount of time as the 1 Hz master, so it gets reset at the exact point it was going to reset anyway.

ok ok so if i need two oscillators synchronized i must use for the slave a multiple frequency of the master. ex : osc master at 0.25 hz and slave at 2hz.
i must be careful with the frequency ratio and it will be synchronized, that' s it ?

If that's how you want them synchronized. They're still synchronized either way, but if the slave is an integer multiple of the master, it will be harmonically related and sound like the fundamental will be that integer multiple of the master.

If it isn't an integer multiple, then the slave gets reset in mid-cycle. However, it will reset at the exact same rate as the master, so the overall output of the slave is still be in sync with the master. The wavelength is the same as the master, so the fundamental is the same as the master. It just has that sudden jump in it.

If all you want is for two [phasor~]s to be integer multiples, it would be much easier to just do this:

[phasor~]
|
[*~ 2] <-- integer multiple
|
[wrap~]

i need several oscillators synchronized without little ramp
so if i take care about frequency ratio it works very well.
it was not very complicated...

thank you !
