The more I read this, the more I think Grant is pulling our leg.  This is a
good example of feature creep.  Welcome to marketing 101. :-)

> Variable CV in 1-4
> CV out 1-4
> Run Pulse in
> Stop Pulse in
> Speech out jack
> Gate out jack
> Trig out jack
> Gate in jack
> Trig in jack = 19

> Pushbuttons:

> Run / Stop = 2

> CV offset 1-4
> CV attenuator 1-4
> Ouput slew 1-4 = 12

> 5 pin DIN:
> MIDI in
> MIDI out
> DIN in or out = 3

> DB9 for programing interface

> LEDs:
> 
> CV indicators 1-4
> Run / Stop LEDs = 6 total
