For years I've wanted to probe deeper into the workings of The Oscilloscope Artist...

Half of the circuit is four classic Schmitt Trigger/Integrator LFOs and that part I understand. It's the second part, particularly the phase shifting, that I'd like to understand better.

I'm not familiar with any circuit simulators although I've read about most of them. What do you suggest? I'm in the Mac universe.

It would be nice to have a model of the LFO to start with. Thanks in advance!
