[sdiy] Minimoog schemos and few questions about I2S...

[Matti Leino]

Hi there!

So, now I'm bothering you with few questions, again...:

My friend want's me to build him a retro-minimoog, just like it was. So now 
I would love to have schematics for it. I have few schemos, like filter, 
but he want's as close original as possible. I couldn't find, I tryied 
hyperreal and synthfool and google, but no results so far...

And then questions about I2S. I have SB Live! in my PC, but I'm not 
satisfied with quality of it's line inputs. I heard, it uses Philips ADC, 
which aren't good in quality. Signal is clipping in something like 
-6...-3dB level. That's not good. I have checked configuration in n-track, 
but nothing to do. I also use little program in Linux, what me and my 
friend wrote, but all the same. Now I want to make ADC, which converts 
analog signal from my mixer, to I2S, which I could feed directly into 
Live's on-board connector. Has anyone tryied this? I checked, Crystal has 
few nice ADC's, +5V supply, 48kHz sample rate, serial output (I2S). There's 
few models, 18-bit, and 20-bit. I have designed the circuit, but of course 
it would be nice to compare schemos, if someone has done this before.

Thanks in advance!

-Matti
