[sdiy] Korg Delta modification question...

[Ordeish at aol.com]

 Hi all, ive just been playing around with my Korg Delta, and thought about a few things that would make it really really nice. wondering if anyone out there would be able to give me suggests or someone who could do it for me. 
 Here is what I want:

 1) Input for the wonderful filter
 2) seperate out for: noise, envelope generator(including eg depth),    and LFO.

 anyone know what i should do about this? I am sure it can be done, just dont know where to start, or who to find.

 thanks
