I had seen the Eventide doc and block diagram flowchart before, but I am really liking that SDD-320 breakdown.  With fresh eyes, I should probably adapt that Program to use the 3 onboard HotSwitches + 3 Aux switches, or a full complement of 6 Aux switches to cover all of those potential modes.

My goal back then was to make it as hand-free as I could, and still cover some of the variations.  I don’t recall if I tried that “differentiated square wave” – Nick Rose’s description for the Peak waveform – but you might try that Program tweak in its double out-of-phase format.  It may / may not capture the trapezoidal lopsidedness a bit better.  I do remember that I had my reasons to choose double Triangle over double Sine.
