Our basic idea responds into the simple function to express the XY-Axis of the Joystick as 2 Values that are linearly mapped onto Out CV1 and Out CV2. So one axis gave us values between 0 and ~25000, which we simply mapped onto 0-10V. The following was to make a function which is summing the two axis into one value. We simply wrote a average function which, when activated, sums the the two Joystick values and maps them once again to 0-10V. We called this "Sum-Mode" and its accesible through pushing the joystick button one time. The State of these two Modes is indicated through the blue LED (on - SumMode [Out CV 1 = Out CV 2] , off - NormalMode [Out CV 1 = X-Axis ; Out CV2 = Y-Axis]). So the second CV Output becomes a copy of the first when the SumMode is active. So this Mode could also be used as a multiple. | Our basic idea responds into the simple function to express the XY-Axis of the Joystick as 2 Values that are linearly mapped onto Out CV1 and Out CV2.

The idea of these modes is to mix the voltage generated by the Joystick with different functions. Or, in other words, to make the joystick controlling an offset to different functions. | The idea of these modes is to mix the voltage generated by the Joystick with different functions.
