Murray, another one for you -
I noticed that no matter where I set key tracking, I couldn't seem to find a value or setting that allowed the filter to exactly track the keyboard.

This is useful for "playing" the self-oscillating resonant filter.

I'm not sure if the JX-3P ever supported this, or if it's dependent on filter tuning/settings/resonance, etc.

But personally I would find it highly desirable if:
- there was a setting that allowed for "perfect" key tracking
- it was documented

...thanks again!
