Quad Joystick... any ideas? |
  |
|
I am very much in need of joystick controller, ideally for quadrophonic panning, as well as 4 channel mixing possibilites.
Before you mention the Trogotronic Iron Cross, I will point out that it makes me drool, and given no other options I will likely get one and try to reverse engineer it alien UFO style.
I have seen some Polyfusion schematics around in the past, but never one for the sound around. Plenty of joysticks are at the ready.
Thanks to all. |

This is completely off the top of my head, as the joystick module I made a while ago is in cold storage (and I probably haven't thought it through) but... have a look at Ken Stone's joystick controller. If it was set up to give -5/+5 volts per axis, and there were two outputs per axis (physically two sets of circuits) then invert the -5 volts on both axes. This would give zero to +5 volts in four directions on four outputs... how useful is that? With four VCA's, it could be used for the mixer idea you talked about. I know nothing about quadraphonics ( I can barely spell it) but it's a start...
It's fairly obvious I haven't thought this through, but I'll drag my joystick module out tonight and have a look.
If anyone thinks I'm talking through my hat, feel free to step in... |

isn't that just for switching? anyway, if you have some analog joysticks, it's not too difficult to make what you are after. you have 4 vcas? you can use just one joystick for quadraphonic panning with some other circuitry (like the sound-a-round?) or/and you can automate it with a quadrature LFO.
i guess ken stone's cct. is a good place to look- if i recall it right, i think there is a schematic for the wiard controller on grant richter's site and it is as simple as it gets.
i built one of my own a while back and plan to build more (someday) as it is super useful and fun to play with.

For a quite different joystick controller idea that I haven't seen done anywhere before, head over to the Design section of my webpage:
http://deathlehem.com/wsb4569662402/design.html
Go all the way down to the bottom of the page. That's where I start babbling about my Quadraxii P.R.O.B.E.  A 4 axis joystick controller, with 1 hand.
(1 joystick's stem, is mounted directly to the end of another joystick. 1 is mounted in the panel, and the other 1 is up in the air.)
The schematic of V1.00 is up there as well. And SOMEwhere on one of my 2 main webpages, is a video of it in operation. Too tired at the moment though, to remember where. Sorry about that. 
All of the build details are there though.  |
