More joystick ramblings. I just got am e-mail from Terry concerning an old
PAiA joystick circuit. I don't care for the circuit layout as-is, BUT,
there is one idea in there that excited me a LOT about my upcoming joystick
panel. This circuit has CV IN for the X and Y axis.

So, adapting that idea to my joystick circuit with the two outputs (one
inverted and one not), the joystick panel can double as a dual inverting
(or not) attenuator. The CV input would override the joystick input to the
buffer op amp. That could be supervised by the panel jack switch. Oh boy,
I am excited now !!

And, while I was working on my schematic, I finally decided what I am going
to do with that dang button on top. It will have two functions.

mode 1: When the button is pressed. Voltage on all 4 outputs goes to
zero. I think I have this figured out. To me this would make it very easy
to adjust the "trim" or "offset" to the exact zero point by ear quickly.

mode 2: Button generates a gate (and maybe trigger) when depressed. Since
there is only one button, I can't really see the need for a trigger, if 800
EG are set up to work on gate only. I think it would be real cool to maybe
hook the joystick up to a filter like the 420. Use the joystick CV out to
one of the filter CVs in and the use the gate out to a 800 EG. Then use
the EG out to one of the other CVs in on the 420. You could then use the
stick to control filter cutoff and at the same time retrigger the envelope
over and over from any joystick position.

So, lets here from some others that may be planning wild joystick panels.
