K3 - 4.22 APF Tune Rate

[k6dgw]

My APF in 4.22 tunes in 10Hz steps ... .50, .51, .52 ... I thought it
was supposed to be 5Hz steps ... .500, .505, .510 ... that's what the
release notes say [I think].  When I ask these questions, it almost
always turns out to be a technical difficulty in my mind, feel free to
point that out, I'm used to it.

I tunes in 5 Hz steps, display resolution is limited to 10 Hz.  For
example, tune to your PITCH frequency and note the * that appear.  Now
move the APF up slightly, the asterisk will disappear but the display
will remain the same.  One more "click" and it'll show the next 10 Hz step.

Fred,

It's really tuning in 5-Hz steps, but only displaying the 10-Hz  
increments. This is consistent with the other filter parameter displays.

Thank you both.  I did notice that the asterisk didn't always appear
when I was on my pitch freq, somehow just blew right past that tidbit of
evidence.  Oh well, APF works really great for me.
