[sdiy] Anyone built a EFM SBM?

[vitreousflux]

Hmm well, I'm not really a newbie to electronics and soldering. Also I have
much experience using the PC softsynths, designing modular synths from the
ground up - some of them very complex. This is where the DIY project comes
in, as I would like to break into hardware now that I've "gone modular and
can't go back"....

The Fatman was one I was considering but it really seems sonically limited
for what I want. Viewing the ASM-1 and SBM PCB's, that should be ok (yet
still a large project) for my soldering skills.

Ummm well the TB303 sound is not really of much interest/usefulness to me, I
mostly use 1 and 2+ osc synths with a lot of slow, flowing filter modulation
and such, customizing is the key. The main idea I have for adding a modular
synth to my studio is the flexibility, control and integration with existing
gear.

Probably the only thing I don't want to jump headlong into is etching my own
PCB's. I have no problem adding small protoboards if I decide to mod or
change the modular (again, provided I go the route of designing the panel
myself)

Thanks for your help!

Rob
