I have found a cheap and effective answer to the problem that requires
no changes to the K3 and no soft in addition to the free version of HRD
that I am using.
I took a mouse apart and removed the opto-wheel's detent spring. The
wheel now spins freely. Although the diameter is small compared to a
"real" tuning knob - I can control the tuning speed from HRD. Works for me.
At some point in the future, I may take another mouse apart and remove
the optical encoder and build a new frame and enclosure for it - then
add a "real" sized tuning knob to same. However, having the smooth
tuning capability along with right and left clicks of the mouse is
really convenient.
