before I went down the path of just adding another VCO (Richter Wogglebug, MANGROVE, Loquelic Iteritas, Manis Iteritas, Cursus Iteritas were in the HP range I was considering) I did searches on primary=VCO secondary=LFO because I was wondering if I had LFO covered but then remembered I have Maths and Quadrax (I just today got notification that Perfect Circuit has QX Expander in and ordered immediately!!) so figured I had that realm pretty well covered. Is the Doepfer you recommend sort of a 'specialty' VCO/LFO module then?

Precisely. The module outputs four sines, but each output is offset from the previous one by 90 degrees. So if you were to use each quadrature out to, say, control the Veils, what you would get is a continuous overlap of the different VCA outs, fading in and out of each quadrature-controlled VCA. This can also have some fun with the 321 and especially the Sirius' Veil, plus you might find a couple of these outputs amusing for modulating the FX Aid XL by using the 180-degree-opposed outs.
