I have the EDP Wasp schematics and I'll scan them when I have time, but 
they're
on one huge (A1 size = 8 x A4 !!!) sheet, so it'll take me ages to piece 
it all together.
Don't hold your breath.  Ask again in a month or two.

Making the Wasp modular will probably be more difficult than you think.  
The
oscillators are DCOs, with PLLs to allow glide.  The whole thing runs off 
+9v, 
regulated down to +5v for most of the CMOS, so there will be the DC bias 
to
think about - if you get that wrong or change the signal levels and it 
won't sound
the same.  An easier option would be to build it like the original, but 
use an
8052 to replace the DCOs and provide midi.
