Quick Start
2
Play the keyboard or strike the pads to hear the sound.
2. The large characters in the upper part of the LCD 
screen will be highlighted.
These are the program number and program name 
(“Program Select”).
In this state, you can press the  /  switches to 
select the next or previously numbered program.
You can turn the VALUE dial to switch programs in 
larger steps.
Tip:
 If you’ve pressed the LCD screen to move to 
another page, pressing the EXIT switch up to four 
times will return you to the state in which you can 
select programs.
3. Use the BANK SELECT INT A–G and USER A–G 
switches to select programs of other banks.
Selecting Programs by Category
There are other ways to select programs, but here we’ll 
explain how to select programs by their category, such 
as keyboard, organ, bass, or drum sounds.
For other ways to select programs, see “Selecting 
Programs” on page 43.
1. In the LCD screen, press the Category popup 
button. 
This is the rectangle located above the program name.
A menu will appear.
2. Use the tabs at the left to select a category. 
The space on the right will then show all of the 
Programs in that category, in all of the internal banks. 
If you like, you can use sub-categories to narrow the 
selection:
3. After selecting a category, you can then press one 
of the inner tabs to select a sub-category. 
You won’t be able to select a category or sub-category 
that hasn’t been assigned to any program.
4. Select a program from the list. 
You can either press a program within the list, or use 
the /  switches.
5. If not all the items in the list can be shown in the 
screen, use the scroll bars to view the rest of the 
list.
6. When you’ve found a program you like, press the 
OK button to close the dialog box. Then go ahead 
and play the selected program!
Program Bank Contents
OASYS ships from the factory with over a thousand 
Programs loaded into memory. Another 768 Program 
slots are left open (“initialized”) for your own 
programming, or additional sound libraries. All of the 
factory Programs can be over-written with your own 
edits, if desired–except for the GM banks.
As shipped from the factory, the contents of the 
Program Banks are as follows:

 The factory Programs in INT-E require the EXs1 
ROM Expansion PCM; similarly, the factory 
Programs in USER-A require the EXs2 Concert 
Grand Piano PCM. If the appropriate EXs data isn’t 
loaded, the Programs won’t sound correctly.
The factory Combinations in INT-C also require 
EXs1 to be loaded.
With the factory-installed 1GB of RAM, you can use 
either EXs1 or EXs2–but not both at the same time. 
As shipped from the factory, EXs1 is loaded, so the 
Programs in bank INT-E will play correctly. 
For details on how to load EXs data, see “Selecting 
which EXs PCM data is loaded” on page 32.

 You can press the INT G switch repeatedly to 
cycle through banks GM, g(1)…g(9), and g(d).
Selecting combinations
1. Press the MODE COMBI switch (the LED will 
light) to enter Combination mode.
Once you’re in Combi mode, you can select and play 
Combinations in the same way as you did Programs. 
For more details, see “Selecting Programs by bank and 
number” on page 1 and “Selecting Programs by 
Category” on page 2.
