Sanderexpander, your comment got me thinking about oscillators, and what you might need lots of 'em for.
More than 3 of these particular oscillators would probably be too CPU-intensive for most machines. Even Zebra, which is pretty efficient, seriously gobbles up CPU cycles when more than two oscillators are employed. Fortunately, my favorite patches need only one or two. I've played with SynthMaster in its massive multi-oscillator mode, and my computer just rolls over and dies.
6+ oscillators serves just two purposes, as near as I can tell: emulating Hammond sounds and building up EDM supersaws. No general-purpose synthesizer nails Hammond sounds anyway (you'd need 96 oscillators to do that) and I hate supersaws, which grate on my ears.
So I'm not impressed by synths that advertise many oscillators. It's easy enough for any developer to add any number of oscillators - it's literally cut 'n paste. Most devs don't bother, because it's what each oscillator can do, rather than how many times you do it in parallel.
You have to ask yourself why multiple oscillators are used in the first place. The answer is spectral modulation. The Minimoog sounded great because its oscillators were inherently unstable. As they slowly drifted in pitch they modulated one another's harmonics in a crude simulation of what happens when acoustical instruments play together. The Micromoog emulated that in an even cruder way, with pulse-width modulation. But there are diminishing returns when adding more oscillators.
My favorite new synth right now is OBXD, a free Oberheim emulation. Like the original Oberheim Expander Module, it has just two basic oscillators.
