If you simply want to control our MS-10/20 from the A-155 such a converter
is not obligatory. You may use the CV coming from the A-155 directly without
any converter. Only the control scale of the A-155 rotary knobs is then a
bit non-linear. But as a sequence is usually adjusted by ear but not by
visual control of the knob positions this should be harmless. Only the
quantizer A-156 cannot be used then (unless you use the modulation input
which can be adjusted to 1V/oct, details on the FAQ page of our website).

P.S. I'm not even sure if the SQ-10 used linear or logarithmic pots. Maybe
someone knows details.
