Certainly but (please correct me if I'm wrong) when I see the
complexity of this thing, I have the feeling that this is the typical
type of module that would benefit from being design around a uP
or a DSP...
The 2 main VCOs could remain analog, but all WF combinations
(and probably many other ones) could be handled by software.
Thus, quite a lot of time & $$ could be saved, or better spent on
(for instance) a realtime LCD display of the output waveforms...

Just a suggestion...
