Intuitive Data Entry

Many parameters have values that correspond to standard physical controllers. In many cases, you can select these values “intuitively,” rather than having to scroll through the Control Source list. This is done by selecting the desired parameter, then holding the ENTER button while moving the desired physical control.

For example, on the LAYER page in the Program Editor, you can set the range of the currently selected layer as follows: use the cursor buttons to move the cursor to the value for the LoKey parameter, press (and hold) the Enter button, then press the note you wish to be the lowest note for the currently displayed layer. The note you triggered (it has to be between C 0—C 8) will appear as the value for the LoKey parameter. Repeat the process for the HiKey parameter.

Another example: select Program 199 while in Program mode. Press Edit to enter the Program Editor. Press the PITCH soft button to select the PITCH page. Move the cursor to the Src1 parameter. Hold the Enter button, and move the Pitch Wheel. PWheel will be selected as the value for Src1.

You can also use the keyboard to choose control sources, since most key numbers correspond to a value on the control source list. If you have a certain control source that you use over and over (for example, LFO1), this can be the quickest way to enter its value. To do this: highlight a parameter which uses a value from the control source list, hold down Enter, then strike the key corresponding to the control source you want to choose. LFO1, for example, is assigned to B5. You’ll find a complete chart of these keyboard shortcuts at the end of Chapter 4 of the Musician’s Reference.

Also, for almost every parameter, you can hold the Enter button and move the Data Slider to run through the range of values for the currently selected parameter. This is not as precise as the Alpha Wheel, but much faster.
