f LCD CONTRAST
Sets the contrast level of the LCD display. Use-
ful for better viewing at different angles and light
conditions.
f USB CONTROL
Setting this parameter ON should only be done
when USB is connected. When this is ON, the
MIDI in and out connectors are disabled and
instead, MIDI is routed in and out via the USB
connector only. When USB CONTROL is set to
OFF, MIDI is disabled over USB and instead, the
MIDI in and out connectors function for MIDI.
f GLOBAL NATURALPLAY
When this parameter is enabled it forces all
harmony to a predefined NATURALPLAY mode
for all presets. This is for use when multiple inputs
are used simultaneously yet only one is to be ac-
cepted for harmony control. The default for this
parameter is OFF.
f GLOBAL KEY/SCALE
When this parameter is ON (default), the Key
and Scale set for a NATURALPLAY SCALE pre-
set affects all presets. This allows you to browse
SCALE presets without having to change Key
every time. In this mode, Key and Scale settings
are not saved with a STORE action. When set to
OFF, key and scale is configurable per preset.
f GLOBAL TAP TEMPO
When set to ON, all presets with Delay
SOURCE set to TAP will share the same tempo.
When set to OFF (default), the preset’s tempo is
recalled with a preset but can be changed via TAP.
f TUNEREF
This trims the overall tuning reference for Har-
mony and Hardtune with respect to A-440 Hz.
This is used when an accompanying instrument
has changed overall pitch such as a piano that is
in tune with itself but not with A=440.
