    Please keep in mind, I have not actually ever built an ASM-1, but, I have built a few modulars.

    The costs when you scratch build, build up very quickly...in fact, it is amazing how fast they build up.  My recomendation is get yourself a Mouser catalog (http://www.mouser.com) and a Digikey Catalog (http://www.digikey.com)...of course, I am making the assumption you are in the states...if you are in Europe or elsewhere, you will need to get the equivilent catalogs...Start making a list of the
things you will need and the quantities.  You will quickly get an idea of how much the project is going to cost.  Don't let it deter you.  You don't need to buy everything right now.  Buy a little bit each month...it doesn't hurt quite as much.

It defaults to V/Oct, and while reading the info on Magnus' ASM-1 page, it never actually explicitly stated that it takes V/Oct for pitch control voltages, though V/Oct was mentioned on filters and things, so I thought it would be a good idea to ask just to be certain.

    The Paia midi->CV will work just fine.  The ASM-1 is intended for 1V/oct.

Going by the circuit section listing on the page, it looks like the noise source and 'cv glide buffer' are missing... where are these? Also, the oscillater design was also marked '1 of 2'... is there a second page I'm missing, or is this an error?
