What I'm basically doing is turning two wired Xbox 360 controllers into a MIDI controller for live composing and mixing etc. Two controllers will be permanently attached to a USB hub along with a 2gig thumb drive, and the hub will plug into my PC. The PC will recognize all three devices as what they are, and from there I will use software to convert the controller's signals to MIDI signals.
In other words, I could plug in my new device into a 360 or PC and it'll function like two usable controllers, but the finished project will appear to be a MIDI mixer.
I'm stripping down the controllers to nothing but the board, and then wiring new buttons/etc. to them so that they will both sit inside a project box with it's own buttons on the outside. I have basic knowledge of soldering and small electronics, and I also have help from an experienced electronics repair... person. The buttons should be pretty easy, as I'm just attaching wires onto existing contacts, which there are already many well documented methods of doing.
The problem I'm running up against is that I will also be using the joysticks as knobs and faders. This means I have to take out the currently installed potentiometers and replace them with my own store bought pots. The new pots must pass a signal identical to the old ones.
So at the risk of sounding like a complete noob (which I am anyways), what type of pots will I need? I know about soldering, and I know the theory of small electronics, but I do not know anything about the math. I don't want to go sticking any old pot I find from a guitar or something into my project only to find out that the data only goes from 0 to 67 or something instead of 0 to 99 like it's supposed to. If I have my slider or knob to 50% then it should be the same as if the joystick was centered and not being touched.
So, to reiterate and summarize and whatnot: What type of potentiometer do I replace the stock pots with in a wired Xbox 360 controller?
Thank you for your help
