Elektor Formant Modular

Hello Augusto,

The Formant 2000 Book was released in the Year 2000.

There are descriptions and schematics of some new modules, like a new 
VCO (without the obsolete uA726 dual transistor), a transistor ladder 
VCF, divider, modulation sequencer and a big 3 track 16 step 
sequencer.

keep attention there are some mistakes in some of the schematics and 
layouts.
 
I have built a Modular synth based on modules of this book. i will 
post some pictures of it soon.
