Title: How would you phase cancel two sine waves?
Post by: ARNK on December 25, 2019, 06:31:07 PM

Just for fun. I want to flip the phase of two sine waves so they cancel out. Using LFO 1 & 2, shouldn't it be the case I'd hear nothing setting the phase 180 degrees setting the destination to OSC 1 & 2 Level?

The Pro 2 phase offset applies to the LFOs and not the wave shape. To cancel a waveform, you'd need these things:

(1) The oscillators need to be 180 degrees out of phase. That is, you need one sine wave and one cosine wave. It doesn't look like the Pro 2 has a cosine wave, nor a phase offset for oscillators

(2) The oscillators need to be at the same pitch, so that the cycles (one normal, one offset) start at the same time always

(3) The amplitude of each oscillator would need to be the same so that the sum of the amplitudes is always zero
