What if I provided a special MIDI CC that allowed the on/off per harmonic function to be used even though the harmonics were actually stored in one parameter?

Subject: Re: [korgpolyex] question for HAWK-800 owners

I'm a bit resistant to this idea, I'm afraid. This is mainly because 
it makes it more difficult to edit the Poly/EX-800 from an external 
editor (like my Novation XStation, for example).
It's relatively easy to setup a hardware control to send out the 
relevant control data, but the result of using that control makes no 
intuitive sense, and it's not possible to program useful feedback on 
what a given value actually means, on most hardware controllers. A 
simple serial of on/off buttons, on the other hand, are much easier to 
deal with.

Just my initial feeling. I'd also say that if an LFO mapped to the 
harmonics is just going to turn the preset harmonics on and off 
(rather than fading them in and out smoothly), I'm not completely 
convinced I'd ever find a use for that particular functionality, to be 
honest.
