Hello Ralph and Co.
The tuning knob could be notched and calabrated? And a readout of some sort desribing just how much variation is being produced.
In another program the mouse scroll can take the tuner 12 complete notches before an octave is reached, each representing the 12 notes of a chromatic scale. Finer tunings or off tunings are possible too.
But the guessing we do with JS tuning is good too, more like a real kit. But I find the knobs in general could use a notch/scrollwheel operation.
thanks Kevin
