[sdiy] decaves?

[John Loffink]

10 isn't as useful as other divisions such as 12, 19, 31, etc.  My web
site has some information on tunings, and links to others with more
info:

With analog synthesizers equal tempered tunings are rather simple.  Just
put an attenuator between the control voltage source and the 1V/oct
inputs to the VCOs.  For best results put a low impedance DC driver
after the attenuator when driving multiple VCOs.
