Yes, forgot about that. a diode for each bit output of the BCD switches.
Mine are 10 position with one common and 4 bit outs, so a minimum of 4
diodes at each switch. I planed on an pair for each step to count at least
an octave. So figure to use the Pro-one DAC, 6 bits per stage x 16 stages
equal 96 diodes. Not too bad.
Oh well, good luck on your design!
