VALUE dial
Use this dial to edit the selected parameter’s value. 
This control is convenient when you want to scroll 
through a very long list of selections.
0-9, –, ., and ENTER buttons
These buttons are convenient when you know the 
exact value that you want to enter. Use the 0–9, –, and 
decimal (.) buttons to enter the value, and then press 
the ENTER button to confirm the entry. 
The – button inverts the sign (+/–) of the parameter 
value; the decimal (.) button inserts a decimal, for 
entering fractional values.
Special functions of the ENTER button
ENTER has a few special functions when it is pressed 
in combination with other buttons.
Whenever an on-screen parameter lets you enter a 
musical note (such as G4 or C#2), or a velocity level, 
you can enter the note or velocity directly by holding 
down ENTER while playing a note on the keyboard.
By holding down the ENTER button while you press a 
numeric button (0–9), you can select up to ten menu 
commands from the current page. 
In Program and Combination modes, you can hold 
down the ENTER button and press the SEQUENCER 
REC/WRITE button to use the Auto Song Setup 
function. This imports the current Program or Combi 
into Sequence mode for quick and easy recording.
9. MODE buttons
OASYS has six different operational modes, each one 
optimized for a specific set of functions. These buttons 
select the current mode.
Each button has an LED, which lights up to show the 
mode you’ve selected.
COMBI button
This selects Combination mode, for playing and 
editing complex splits and layers of Programs.
PROG button
This selects Program mode, for playing and editing 
basic sounds.
SEQ button
This selects Sequencer mode, for recording, playing, 
and editing audio and MIDI tracks.
SAMPLING button
This selects Sampling mode, for recording and editing 
audio samples and multisamples.
GLOBAL button
This selects Global mode, for making overall settings, 
editing Wave Sequences and Drum Kits, and more.
DISK button
This selects Disk mode, for saving and loading data to 
and from the internal hard drive or CD-RW drive, or 
from external USB 2.0 storage devices.
10. UTILITY buttons
HELP button
The HELP button gives you built-in, context-sensitive 
access to the user manuals, right from the front panel. 
For information on any front-panel button, knob, 
slider, or real-time controller, just hold down HELP 
and then press the button or move the controller in 
question.
For information on the current LCD page, press and 
release the HELP button.
While the help page is on the screen, you can touch any 
of the on-screen links (hilighted in blue text) for more 
information. You can scroll through the text by using 
the on-screen scroll bars, pressing the Inc and Dec 
buttons, or spinning the Value dial.
The top of the Help page has “breadcrumb” links, 
which show the hierarchy of pages above the current 
one. Touch any of these links to jump to the 
corresponding page.
The backwards and forwards buttons function like the 
similar buttons on a standard web browser. If you use 
links to jump between pages, you can then use the 
backwards and forwards buttons to move through the 
pages you’ve already viewed.
The Contents page lets you access any part of the Help 
system, including almost all of the text and graphics in 
both the Parameter and Operation Guides. The Index 
contains a shorter list of links to important articles.
To close the help display, just press the HELP button 
again, or press the on-screen Done button.
RESET CONTROLS button
This feature lets you reset the Vector Joystick to the 
center position, or reset any of the Control Surface 
sliders, knobs, or switches to their saved value.
