Hi Erik,

I am very sorry that you stopped your project. I know there are several
errors in the book, but at least I could find a solution for every
problem:

1.) I used only the schematics of the book and routed every pcb on my
own. That reduced the amount of errors to ca. 30% and I was able put
more than one module on one eurocard in several cases.

2.) There are several pages in the web which contain solutions for
schematic, partlist and pcb layout errors of the book. If you are
interested I send you a link list.

3.) Mr. Helmstedt, the author of the book, helped me when I phoned him
and asked questions.

Until now I finnished 2 VCOs, 3 VCAs, 2 ADSRs, 1 VCF, 1 OUTPUT and 1
GATE DISTRIBUTOR Module and they work fine. You can visit my homepage
www.analog-monster.de to have a look.

Buildung analogue modular synthesizers is one of the most beautiful
hobbies I can imagine, and I learned a lot. So if you think about
restarting your project, perhaps I can help you in one or another point.

Regards
