But doesn't a linear (Hz/Volt) synthesizer with a keyboard nearly always
have an exponential convertor in it to convert the control voltages coming
from the keyboard or voice assigner DAC (which are 'linear' in nature, as
in 0 1 2 3) to exponential control voltages (as in 1 2 4 8) for the linear
VCOs?
