env-2a note

[Massimo Sanna]

Hello Andrew

there must be more than a wrong diode on my ENV2 board :-( 
  I didn't get  it work,  so -shame on me- I have built a clone of MS20'
envelope generator
(working).  If anyone is interested, I have ready the pcb drawing in
Easytrax format   :-)


          best  regards
