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. :) Larry H
