Calibrated V/Oct response adds one usefull application: Transposing the
shift oscillator in parallel with the VCOs (or whatever input sound). So
you can get the same (harmonic or non-harmonic) partials over the whole
keyboard range. Not a FS's most important function, but a nice one
nevertheless. See http://home.t-online.de/home/jhaible/hj_fs.html (#1).
