Hmmm... 
As i am in the process of building my own polsynth which uses SID
chips for its voices, i am thinking about keeping them in tune.
These chips derive their clock from an 1 MHz crystal oscillator.
Would it be better to use an extra oscillator for every voice card,
or shall i use one master oscillator and distribute this clock ?
(i hate the idea of having an 1 MHz square signal all over the synth,
even if the frequency itself nor the harmonics will be far above audio range)

Any thoughts ?
