The different solutions look really interesting...i was reading an old pdf of the PAIA PROTEUS,from 1981,a programable analog synth...the patches were stored by multiplexing cv pots and rotary switches,wired as voltage dividers...stored in ram,and then demultiplexed to generate cvs to control the analog circuitry...i've been dreaming of using this aproach in a more modern version,with an lcd I supose midibox or mios would be the perfect platform...reading the pots,storing in banksticks,generating the cvs,and full midi control...wow! Tell me if this looks like an interesting project... Thanks for all Your hard work and inspiration TK !!!
