hi paul, you may want to try using the A185 bus access module for
driving the 1/oct inputs of the roland 100, instead of multing for
greater accuracy. it has buffered outputs and different jumper
settings for more accurate cv and gate distribution.

check this url for more info,

A Systems and A Solutions both have different versions of the same
idea which may suit your fancy better. good luck.

regards,
RM
