"I think this is done, and the design exposes enough underlying modulation flexibility to get lots of interesting sounds out of it. Now I need to tweak the code to represent all the new LEDs and tweak the existing LED positions in the overlay geometry to align with the rendered underlay. Should be done before the end of Saturday, tomorrow I'm on other stuff.
Note the VCA block, 'EG2=>A' and 'EG2=>B' - this is to allow stealing of the noise EG (EG2) to allow each oscillator to ramp independently. Both OSCs (in fact everything) is still envelope shaped by EG3 right st the end of the signal chain, but earlier on during modulation EG2 can now be applied to one of the OSCs. This could give some really interesting richness if a more harmonic-rich wave is ramped up slightly more slowly than the other, harmonic-poor wave, to add yet more movement to the attack. Experimenting with this by pulling on the OSCB slider while hitting notes leads me to believe that this could be a killer feature.
Here's an interesting observation for those who can count - notice that every modulation template (the stuff enclosed by blue lines on the right) has 16 options - 2x2x4 or 4x4. So every template is just one of 16 possibilities, 7 templates (VCA, phase, pitch, filter, LFO0, LFO1, MOD/CHANPR) so just 7 switch statements and a tiny burst of multiply-accumulates and I'm done. So the new modulation matrix code should be way, way quicker than the old one. I just need to write it ..."
