You might want to post in the DIY section rather than here.
Cheers,

Currently i'm planning to build a mainly diy modular synth. A main difference between my attempt and others is to have a single 'basic' instrument with an integrated keyboard (49 keys) since i want to be able to move it around in one piece. I came up with an ms-20 like design (see attached pic). The modules planned are (from left to right):

The MS-20 is my favourite modular ever. I had a Doepfer and there was some things that annoyed me about it.
3.5mm contacts... the cable connectors and the cliff females didn't seem to be matched so some functions would
just be more or less glitchy and there wasn't any idea to mod it with normalising the contacts... which is the
no.1 biggest advantage with the MS-20... you can patch the hell out of it, but you don't have to
| Quote: | | key encoder: simply converts the key strokes into control voltages and gate + trigger pulses, also provides midi output (simply note on and note off) |
Don't forget a S/H. You need one integrated with the key encoder. ( I hope I don't overexplain things ( I'm
not an expert myself  )).
| Quote: | | 2 * VCO's: standard sawtooth-based vco's, including doepfer-inspired temperature compensation |
I would look into the cmos chips. I would definitely have an XOR "ring modulator" like the MS-20 or actually
a whole CD4070 quad XOR and have some hardwired to the VCO's and LFO's and some patch only...
| Quote: | | PolyAVR: a midi-controllable digital polyphonic synth module http://moads.100webspace.net. All parameters except waveform select is voltage controllable. This is a important module for my specific setup since i want to be able to use this instrument also for simple pads beside experimental sounds |
Wow! I'll look into this too...
| Quote: | | LFO: A Triagular wave based LFO, signal shapable to saw and ramp |
The one on the MS-10 is a quick build but unfortunately it doesn't sweep over enough range. Chanses
are you'll upgrade pretty soon if you choose it anyway
VCA's: two simple vca's with linear CV response
| Quote: | | Sample and Hold + Noise: a sample and hold module + White noise out |
I don't know about you but to me the most fun with a modular is using sample and hold circuits for
downsampling/analog rate reducing. Hours and hours just disappear. Make sure your S/H go up to audiorange
