Global Edit Mode is where you will find several parameters which affect the entire
instrument, such as overall master tuning, display contrast, controller settings,
keyboard mode, edit mode and the 48 kHz input.

Editing Global Parameters

¿
Press the [ GLOBAL] button.
The display will change to Global Edit Mode, page 1 . The total number of pages
(seven) is indicated in the lower left corner of the display. The currently selected
page number will be underlined.

There are four parameters available for editing in Global Edit Page 1:
Quad Knob [1] controls the display contrast.
Quad Knob [2] enables General MIDI Mode and recalls Mix 00 of Preset Bank 4.
Quad Knob [3] controls the transposition, or pitch, of the keyboard.
Quad Knob [4] controls the instrument's overall master tuning.
¬
Use the PAGE [¨] and [Æ] buttons to scroll through the 7 pages of Global Mode.
The following sections describe in detail each of the parameters found in the seven
Global Edit Mode pages.

LCD Contrast

In Page 1 of Global Edit Mode, Quad Knob [1] adjusts the LCD Display Contrast (00
to 121). Whenever the [GLOBAL] button is pressed, the display will always revert to
Page 1 with the Display Contrast parameter selected. This is so that if the display
contrast is set too high or too low and is unreadable, you can easily adjust it even if
you can't see what you're doing.

General MIDI Mode

In Page 1 of Global Edit Mode, selecting Quad Button [2] and pressing VALUE [π ]
enables General MIDI Mode. This will immediately take you out of Global Edit Mode
and into Mix Mode, automatically selecting Mix 00 of Preset Bank 4. For more
information about General MIDI, refer to the MIDI Supplement in Appendix B.

Enabling General MIDI Mode via MIDI

The S4 will respond to a universal MIDI Sysex message to turn General MIDI mode
on or off. Some (but not all) General MIDI sequences will have a Sysex message at
the beginning (bar 1) which tells the receiving device to go into its General MIDI
mode. If this message is sent, no matter where you happen to be on the S4, General
MIDI mode will be enabled, and Mix 00 of Preset Bank 4 will automatically be
selected.

Master Pitch and Master Tuning

In Page 1 of Global Edit Mode, Quad Knob [3] adjusts the S4 Plus's overall pitch (-12
to +12/up or down an octave). Adjust this parameter when you wish to globally
