Sounds like we're all shrinking rapidly .. no time to lose, team!!
Let me briefly describe what I'm hoping to achieve with this -- once I start actually contributing, that is ..
I'd personally like to emulate what Compton (and later Makin) did with this arrangement, originally using spinning electrostatic disks, and then during the 1980s with 'solid state'. Compton actually used to build huge 4-manual and pedal 'pipeless' organs with a only a single set of 12 spinning disks! Not ideal, but ...
Firstly you need way more harmonics than a Hammond, of course, but around 60 suffices for the vast majority of organ stops at various pitches. As regularly noted here, a single set of generators based on equal temperament is most inaccurate for many harmonics, so the Makin arrangement was to have a 'normal' generator set to provide harmonics 1, 2, 3, and all multiples (4, 6, 8, 9, 12 etc); a second set of gens tuned to the 5th harmonic (slightly flat), which is used for 5, 10, 15, 20 etc, and a third set tuned to the 7th harmonic, flatter still, which is used for all the remaining really awkward ones - 7, 11, 13, 14, 17 etc. With MV's current creation being pretty CPU light I'm sure that three like this could easily work in parallel. (And I reckon I can manage this much!)
No drawbars as such .. organ stops become virtual-preset-drawbar-levels (using the 60-odd virtual drawbars), and when you draw more than one stop it simply adds the settings together. It works. It's not the greatest, or most realistic, way to generate 'pipe organ' sound, but does have the major advantage of theoretically enabling a limitless stop-list, manuals and pedals, with negligible extra CPU hit. (Unlike HB3, my other organ emulation ... ) Ah .. def needs a rotary-speaker, I should add; Compton devised a device they called a 'Rotofon'.
Attack & Release durations need to be increased progressively for low notes, but I've already discovered this is easily achievable extending MV's 'click supressor' numbers.
Other details to consider as well but I'll leave it there for now. (Before we shrink any more
)
I'll see if I can come up with such a triple generator expansion soon ... somewhere in my cupboard I have lists of all the numbers, harmonics and stuff!
