Two 'sine tone with phase and gain' generating the same tone are out of phase and maybe drifting, it seems to me. Why?
So if trying to make one 1k, 0 phase and the other 1k, 180 phase and sum them with the summer, they won't cancel. I find a phase where they cancel, but it seems random and it looks like it floats to a

[BUG REPORT]triangle oscillator (e.g.120Hz or 1200Hz) is not periodic
Triangle oscillator is sometimes not periodic even if the frequency is a divisor of the sample frequency (e.g.120Hz or 1200Hz at 48kHz) . Since 48000Hz/1200Hz is an integer, one would expect a perodic
