This is probably an easy one for anyone that is fluent with this system.
What is the simplest way to produce a 90° phase shift on an oscillator output? I'd like to be able to create quadrature oscillators using waveforms other than a sine.
I see that there are some community "phaser" effects, but I do not need or want something with any controls, just a bare-bones, precision 90° shift. I've experimented with phase input controls on some of the oscillators, but it's hard to say if they're working correctly. Signal processing the output would be my preference.
