Dave Smith Instruments SYNTHESIZERS

Hello,

I'm interested in getting an idea of how much work is involved in 
writing a small utility for the Evo/PolyEvo which would enable the 
user to create user waves by additive synthesis; that is, specifying
through graph, the amplitude of harmonics 1-64 (or 1-32 if streamined
version easier).
This has actually been done for the Waldorf Microwave II with the
utility "Wave2 microwave" as well as through Emagic's SoundDiver.
Whats involved with creating a utility like this for the DSI synths?
I work primarily with hardware, and software utilities such as this are 
not my forte. Any input appreciated.


Regards,
