Sure, but Harry, all three of the Arp 2600's i've had
do this... (well, with the VCF freq slider, not the
Q), and i'm not sure we can call the designers of that
machine unenlightend. Yeah, they could have done
better with respect to this (and i wish they
woulda!)... but what are you suggesting in particular?

This is a hard problem to tackle for all, and it's
kind of harsh to come down on the kit manufacturers in
particular.  

On the other hand, if you have particular suggestions,
just let us know! Especially for the 2600 users around
here.  We're all ears, here... though we may talk *way
too much* for ears.
