Modular Synth Panels

Nice set of enhancements.  I agree with them all.  I was working on a 3U panel myself with the small potentiometer spacing but like yours better.  I adapted a version of it in FrontPanelExpress at
http://modularsynthesis.com/jhaible/varislope/varislope.htm

I've used this smaller control spacing on my YUSynth fixed filter bank with a switch in between. It's tight but very usable.  There is a photo at the bottom of this page showing the spacing.

Nice work. - Dave
