[sdiy] My latest project

[Eric Brombaugh]

Tom,

Looks fantastic! You put a lot more care into bending your protoboard 
wires than I do. :)

Presumably you'll condense this down to a small board layout and then 
tie a gang of them together for a poly-synth. Any thoughts on where 
that's going?

Eric

PS - Any sound samples? (ear-pr0n)
