Hi James !
Thank you for writing

I share your opinion. But Mika has some doubts, that the outputsignals !
of the SM305 are square wave. Input from SM304 is not such a big
problem, will be replaced by midi dataformat.

Ahh yes that seems to have sense. Do you fully understand data format
on page 9 ?
I ll add an old CX3 FAQ list on my homepage, to give all interested
people the possibility to get the knowelege that mika and me actually
own.( and i dont forget all our results :-)
In the moment our hardest problem is the need for a microcontroller
with 45 IO ports. There is a SX with 40 IO ports, but that seems to
be maximum. multiplexing could be an solution.
Any ideas ?

ciao
