> When the boards will be available will they come with information on how to set up a main set of pots & switches to control maybe 5 or 6 synth modules simultaneously - so it will be possible to build a polyphonic synth It does not seem to be that simple...but at the same time so very tempting ;-)

We had this already. Te thread subject was "DOEPFER at NAMM 2010". The
direct answer to your question is:

Only the VCF Cutoff, and the VCO tuning are direct voltage controlled
parameters. All parameters of envelope, LFO, and all modulation-amounts,
levels mixing potentiometers, switches are direct parts in the circuitry
and cannot be controlled by a CV (which is essential for a single
controlset).

You might use fourfolded potentiometers, but these are around $20 each...

Or you would build a huge pcb with additional VCAs and CV Switches.
