[sdiy] Linear detuning !

[Gene Stopp]

Yah still here, no DIY this year so not much to add. :(

You can do my trick on most Minimoogs that have not recently been
calibrated, ha ha.

I had a hunch they would not be the same end result, only close. So - if you
tweak the scale and the detune so that C1 had a 1Hz beat, and C5 had a 1Hz
beat, would C2, C3, and C4 beats be above or below 1Hz?

Hi Gene - nice to see you're among us.

As far as I understand it, what you're describing is another trick to make
VCO pairs sound
richer: slightly misadjust the tracking (V/oct scale), and then (partially)
compensate
this by detuning. With this, you have two degrees of freedom, so you can
also
set your desired beat rate for two different notes - a high note and a low
note,
if you like. However, the behaviour in _between_ (change of beat rate
accross the
keyboard) is much different than  with my method.

A third method would be running the whole (V/Oct) CV thru a waveshaper that
bends the response of the VCO ever so slightly.
