Ambika XOR cross modulation

Hello, I don’t understand what is XOR cross modulation. Is it possible to explain or to post a link?

Thank you!

It takes the bit-wise XOR of oscillator 1 output and oscillator 2 output.

It’s like having oscillator 1 sent into an OTO Biscuit whose bit inversion pattern is dynamically controlled at audio rate by oscillator 2! I don’t think there are other synths with this kind of modulation - you don’t really need to understand it! Pure digital destruction which still preserves osc 1 and 2 main frequencies.
