[quote author="lanxe"]about how much would you say the parts run you (minus the enclosure)?[/quote]
It comes as a kit - every PCB component is included.
You do have to provide your own PSU, power transformer, wiring, pots, patch jacks and cables, enclosure, knobs, front panel, etc... The synth is very flexible in terms of how you hook it up, so parts can run real low or real high, depending on how you set it up...
You may also want to put a MIDI-to-CV interface in there... In fact, I strongly suggest you do, for obvious reasons.
I put mine in a 6U rack box, with every possible connection brought out to the front panel - as close to fully modular as you can get, without actually having each module physically separated.
If I had to do it over, I'd add a simple 4-to-1 mixer, a ring modulator (which I think the ASM-2 has), a sub-octave oscillator, and some DC offset pots (a 1M pot between the -15V and 15V power rails, with the wiper brought to a jack in the front panel, to be able to provide a DC offset for CVs).
Even with a 6U box, I had to cut some corners to fit everything I needed in the front panel: the MIDI-to-CV jacks are spaced closer together than the rest of the pots and jacks in the panel, there's only one gate input to trigger both EG's, and the power switch is in the back. Also, there's no way I could've fitted the extras I wanted on this panel!
Here's my baby:
All in all, I seem to remember the whole thing set me back about eight-or-nine hundred dollars.
Peace,
Al.
