[sdiy] Chris Synths polysynth

[Mike Bryant]

> What do you think of his choice of CV DACs? Do all synth CVs really need something as good as DAC7554 or even AD5676?

Possibly not, but it's probably easier for the digital subsystem to use the same DACs everywhere apart from the VCO control voltage where 16 bits was obviously needed.  There are cheaper 8 and 10 bit DACs around but they may have slower digital interfaces or other hassles.
