MOTM

hello all,

i just remembered an idea that came to me as an offshoot to that voltage
source module, and my question to the list is:

would a fixed precision voltage source be practical for tuning purposes - ie
derive the reference voltage for A-440Hz, and just put it out on a jack - to
aid calibration of vcos you could even go as far as make up several switch
selectable octaves

any ideas..? or does experience out there find these things impractical /
innaccurate..?

cheers
