btw Scott rider aka Old Crow used a similar trick to achieve Hz/V 
characteristics with an 8Bit:


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.
