Elektor Formant Modular

true - good idea.  i actually found an old +5V 1.2A supply lying around the house.  .  im thinking i could set up a distributor to send the +5v to a few modules...  see any problem with that?

This helps to a certain extent with bleed but more importantly the accuracy of the CCO. The VCO must be considered as 2 circuits treated separately with +5 +15 -15 and ground for CCO and +15 -15 and ground for Output stages. I think this is mentioned in the original notes.
