User Interface Basics
Data Entry
The Edit Button
The Edit button activates each of the K2661’s editors, and acts as a shortcut to many pages
within the Program Editor. Pressing the Edit button tells the K2661 that you want to change
some aspect of the object marked by the cursor. For example, when a program is selected and
you press Edit, you enter the Program Editor. If a setup is selected, you enter the Setup Editor.
There are editors accessible from just about every operating mode. To enter an editor, choose one
of the modes (mode selection), and press Edit. An editing page for that mode will appear. You
can then select parameters (navigation) and change their values (data entry). If the value of the
selected parameter has its own editing page, pressing the Edit button will take you to that page.
For example, in the Program Editor, on the PITCH page, you might see LFO1 assigned as the
value for Pitch Control Source 1. If you select this parameter (the cursor will highlight its
value—LFO1 in this case), then press the Edit button, you’ll jump to the page where you can
edit the parameters of LFO1. Naturally, you can find every page in the current editor by using
the soft buttons, but often it’s easier to use the Edit button shortcut.
The Exit Button
Press Exit to leave the current editor. If you’ve changed the value of any parameter while in that
editor, the K2661 will ask you whether you want to save your changes before you can leave the
editor. See page 5-3 for information on saving and naming. The Exit button also takes you to
Program mode if you’re on the entry level page of one of the other modes. If at some point you
can’t seem to get where you want to go, press Exit one or more times to return to Program mode,
then try again.
Data Entry
The data entry section of the front panel includes the Alpha wheel, the Plus/Minus buttons, and
the 14-button alphanumeric pad.
The Alpha Wheel
The Alpha Wheel is especially useful because it can quickly enter large or small changes in
value. If you turn the Alpha Wheel one click to the right, you’ll increase the value of the
currently selected parameter by one increment. One click to the left decreases the value by one
increment. If you turn it rapidly, you’ll jump by several increments. You can also use the Alpha
Wheel to enter names when you’re saving objects.
The Plus/Minus Buttons
These buttons are located just under the Alpha Wheel. The Plus button increases the value of the
currently selected parameter by one, and the Minus button decreases it by one. These buttons
are most useful when you’re scrolling through a short list of values, or when you want to be sure
you’re changing the value by one increment at a time. One press of the Plus or Minus button
corresponds to one click to the right or left with the Alpha Wheel. These buttons will repeat if
pressed and held.
Pressing the Plus and Minus buttons simultaneously will move you through the current list of
values in large chunks instead of one by one. Often this is in even increments (10, 100, etc.).
Don’t confuse these buttons with the +/- button on the alphanumeric pad. This button is used
primarily for entering negative numeric values and switching from uppercase to lowercase
letters (and vice versa).
