Hi, 
 
Wanted to start a record of my build of a MS-20 clone, going to build a prototype, thinking about buying a usb controller MS-20 and putting the guts in box. 
Alternatively i wanted to have a more sequential circuits look to it with oak side panels. 
have a list of all the IC's (including an alternative to the korg 35 chip), capacitors, diodes, transistors, resistors, pots and knobs. 
 
will list bits in next post. 
 
Here is a few links of where i got my information, to try and keep it all in one place.
