I want to be able to look at some simple waveforms and see how they change as they go out of phase. I've set up this patch. The waves stay in sync for a few minutes, but slowly become slightly out of sync. The waveC Canvas shows the result of the two waves. If the waves are 0 offset, it should just be a larger sawtooth. However, the wave has a change halfway down the tooth.

@eliotw Hi I took a look at your patch. Everything seems to working as expected. If at anytime you are trying to reset the phase (i.e. set the phase to 0) of waveB to start over of something, make sure you also reset the phase of waveA in order to keep them locked in with each other. I just added a patch cord from the [0( to the right inlet of the waveA [phasor~]. Also, make sure all your gain stages are set to maximum.

Let me know if I'm misunderstanding your problem.

@rjp9 Thanks for taking a look. That was certainly the problem - ha, I even said it in the title - the oscillators weren't in sync. I added phase reset to the first oscillator when i bang the oscillator slider.

Hi Eliot, I also see no problems with the patch, the oscillators behave exactly as I expected. Can you please explain better what is happening for you?

@gsagostinho Here's a screenshot of the problem I was having. After moving the osc2 phase and returning it to zero, the waves weren't lining up. As @rjp9 suggested, I needed to reset osc1 to zero also.

Here's a screenshot of the problem I was having

I see, I had understood the problem was still not solved. Sorry!

Cheers,
