5 Specify the function and parameter for other GPI IN ports in the same way. With these settings when you operate an external device to make the GPI IN port active, the corresponding PM5D function will be executed. (If a continuously-variable parameter is assigned, the parameter value will vary according to the change in voltage.) Hint The settings in the GPI screen apply to all scenes. These settings can also be saved on a memory card as SETUP data. Calibrating the GPI IN ports If necessary, the voltage values at which the PM5D detects Low and High levels can be adjusted appropriately for the voltage of the signals being input from the GPI IN port. You can use this to set the variable range of a PM5D parameter to match the range of voltage change produced by a continuously-variable controller (such as a joystick). 1 Connect an external device to the PM5D's GPI connector. 2 In the DISPLAY ACCESS section, press the [MIDI/REMOTE] key several times to access the GPI screen. 3 In the GPI IN MONITOR area at the upper right of the screen, select the GPI IN port that you want to calibrate. If you are calibrating a two-dimensional controller such as a joystick, click the / buttons at the left and right of the X-AXIS and Y-AXIS fields to specify the two GPI IN ports. If you are calibrating only one GPI IN port, set one of them to "----" (no assignment). 4 Turn on the CALIBRATION button. The red line (or red square) in the GPI IN monitor area will temporarily disappear, and only the yellow symbol will remain. 5 If you are calibrating only one GPI IN port, vary the voltage of the signal being input to the GPI IN port specified in step 3 from the maximum value to the minimum value. The yellow symbol will move up/down or left/right as the voltage changes. The red line will extend according to this change, and the maximum and minimum voltage values for the corresponding GPI IN port will be stored. 6 If you are calibrating a joystick, move the joystick through a 360-degree path. The yellow symbol will rotate. The red square will broaden accordingly, and the maximum and minimum voltage values of the GPI IN ports corresponding to the X-axis and Y-axis will be stored. 7 Turn off the CALIBRATION button. The maximum and minimum voltage values detected will be remembered as the reference values for the High and Low levels. (When controlling a continuously variable parameter, the maximum value and minimum value of that parameter will be aligned with these reference values.) Hint The results of calibration apply to all scenes. They are also preserved even when the PM5D is powered-off. When you specify a GPI IN port, the voltage from that GPI IN port is indicated by a yellow symbol in the GPI IN monitor area. In this case, the horizontal position (X-axis) corresponds to the voltage of the GPI IN port selected in the X-AXIS field, and the vertical position (Y-axis) corresponds to the voltage of the GPI IN port selected in the Y-AXIS field. The red line (or red square) displayed in the GPI IN monitor area indicates the range between High level and Low level for the GPI IN ports corresponding to the Y-axis and X-axis. Hint If necessary, you can click the REVERSE button to invert the Low level and High level of the input signal. (The result is the same as switching the POLARITY setting of the GPI IN port.)
