The recent M420 prescribed mod
Well, not 'intentional'. It's just a matter of do you want the '0' tick mark to be DC or like 8Hz. I use 243K, 255K is fine.

Subject: [motm] The recent M420 prescribed mod

A few days ago I got my 255K resistors to update my M420 VCFs to remove the dead zone on the freq pot at low freq settings.  I was just about to jump in make the mod and then it occurred to me that the pot actually ∗needs∗ a dead zone so that DC levels at the FM inputs would not severly limit the lowest freq setting of the pot.

My question is: Wasn't this dead zone intentionally designed in?  Seems like a classic design tradeoff issue that has now been forgotten.

Can anyone tell my why making the mod is not a no-brainer?
