Very cool!
I want to replace the ribbon cable with a longer one
so that I can feed all the signals (CV, gates etc)
directly into my multi-"Stooge Larry (TM)"-bus (behind
the frontpanels). I'd simply add one more AMP
connector to a cable with is a few inches longer than
the current one and then make a little adaptor board
which then feeds the signals into the multi-bus. The
question is should I add such EMI filters there too?
If so, what's the frequency of the CPU? (I found the
datasheet that shows the correlation between
capacitance and insertion loss).
Many thanks in advance
