Chapter 1. An overview of the RS-5/9
Chapter 1
About Memory
Memory refers to the area where Tones and settings are 
stored. The memory of the RS-5/9 is divided into three areas: 
System Memory, User Memory, and Preset Memory.
There is a Temporary Area within memory, into which data 
is placed when you select a tone or performance, and the 
data in the temporary area is what you are actually playing 
and editing.
System memory
System memory stores system setup settings that determine 
how the RS-5/9 functions.
User Memory
The contents of User Memory can be overwritten, and are 
used to store settings that you create. You can store 128 
Tones and 128 Performances in the User Memory.
Preset Memory
The contents of Preset Memory cannot be rewritten. Preset 
Memory contains 512 tones and 128 performances.
The temporary area
When you select a Tone or Performance, whether to play it, 
or to change the settings, the selected Tone or Performance is 
called up to a temporary holding memory called the 
Temporary Area.
When a Performance is selected, the selected Performance is 
called up to the Temporary Area, and then it is played.
When a tone is selected, the selected Tone is called up to the 
Upper Part or Lower Part of the Performance in the 
Temporary Area, and then that is played. A Performance is 
called up to the Temporary Area at all times.
The Upper or Lower Parts may use any of the Parts 1– 16. 
When the Key Mode is set to Single, the Upper Part is used. 
When Key Mode is set to Split or Dual, both the Upper and 
Lower Parts are used.
The data in memory will be preserved even if the power is 
turned off, and can be recalled at any time. However, the 
data in the temporary area will be lost when the power is 
turned off.
When changing Tone or Performance settings, you don’t 
directly change the settings stored in memory, but rather the 
data called up to the Temporary Area. If you want to keep 
the changed data in the Temporary Area, you must then save 
that data to the User Memory.
As for System settings, changing these settings directly 
affects the data in memory, so the data is always updated. 
Therefore, you do not need to do anything to save this data.
