how about a module that is 6 or so very simple sine generators, with a cv in 
on each for lfo's or env generators, and of course a master freq knob for 
each sine.  Sum all of these at one output and there you go.
maybe even have a few onboard simple lfo's or a/r env. generators
wouldn't this be considered basic FM?
or basic additive?
I posted this idea a month or so ago..   I still think it would be cool   
feasible?
