Hi Larry, et al,

Personally, I'd like a joystick that could mount LATERALLY, that 
is, on top of my keyboard, not in a vertical module setting. Maybe 
attach via velcro.

Two CV outputs -- one for modulation, and one for vibrato would 
be all I'd ever want. I find those pitch/mod wheels on keyboards 
less than desirable. I'd definitely want the joystick to return back 
to "0 volts" when you release it.

You know much more about these things than I -- I'm not big on 
circuit design. Guess it would just need 5+- volts out of both axis, 
right?
What would a push button be for?

Where could you get the pre-made joystick? I wouldn't mind 
taking up a module space for the electronics and jacks.
And a schematic would be excellent, if anyone has one...

Best,

 - Dana
