btw Scott rider aka Old Crow used a similar trick to achieve Hz/V
characteristics with an 8Bit:<br class="">

He uses a dual channel DAC MCP4922. DAC #1 is providing different
reference voltages for each octave, which then are used by the DAC
#2 which converts the same twelve note data to a spreading CV the
higher the octave / refence voltage from DAC#1 respectively is.<br class="">
