A Very, Very, Very Minor K3 Quirk

Let's say you have selected a 2.8 kHz filter. Use the LO CUT control to move the low cut freq to 0.00.

Now turn that same control clockwise and notice that it goes to 0.20, 0.30, 0.40.

Now move the control back down. Notice that it goes to 0.30, 0.20, 0.10, and then finally, 0.00.

So to select 0.10, one must increase past this value, then come back down.

Note that I'm not asking for a firmware fix, just simply pointing out this curious behavior.

I reported that to "headquarters" many months ago.

Hi Al,

There are many strange behaviors in LO CUT/HI CUT mode that have been  
there for a long time.  They aren't usually noticeable in normal day-
to-day operation, but they just make no sense.  If you're curious,  
search the list archives for a message with the subject "K3 - LO CUT/
HI CUT bugs" from November 26, 2008 to see my observations.  Note that  
some of the specific things I point out in that posting don't quite  
work the same way today, but the general theme of odd things happening  
in LO CUT/HI CUT mode remains valid.

I also agree that it should be a low priority item on the to-be-fixed  
list.
