Using MB64 application (it's the one with analog inputs eg. pots) with
patch mode enabled (+AOUT and SHX8 modules) You'll have 128 patches
(sort of "presets") for settings and 64 CV outs.

The s&h mux used in SHX8 is NJU7304D which is discontinued and hard to
find. :( Any cheap alternative eats up mucho board estate (mux + s&h
caps + buffer opamps) and other monolith multichannel s&h amps are
pretty expensive.
