Cool, but you see, I suspected SuperCollider would do things such as clip the phase from phase 0.001 to 0.999 to prevent a harsh sawtooth, and also fade in (ramp) one block when a Synth starts.
I feel it has many such details to make it sound "smoother" and nicer, it also seems to be a little quieter
well, I kind like this, if I have other patches to compare, would you like to check? :)
cheers

OK, here's the updated trials.pd with appropriate phase relationships. The pulse train in SC3 is control rate, so there might be a ramp between values that I'm missing. You can add it and see if it makes a difference.

The documentation is poor on both sides. I had to go into the source code to find out a couple of things. On Feb 16, 2016 9:45 AM, "Alexandre Torres Porres" porres@gmail.com wrote:

Yeah, the phase relationships didn't match those in the SC3 code. I'll send the updated patch when I can get to my computer. On Feb 16, 2016 9:36 AM, "Alexandre Torres Porres" porres@gmail.com wrote:

why? what do you mean? was it wrong?

OK, I had to adjust the Pd patch a little to get it to match the SC3 code. I've made an A/B test: one is SC3 and the other is the matching Pd patch. See if you can tell which one is which, and why you answered the way you did. I went fast and made them 44.1kHz 16-bit; you'll have to live with it. :)
