Yamaha MOTIF XS7 Manuel D’Utilisation

Changes parameter values for each tone generator Part. 
There is no compatibility between different manufacturers. 
Numerous parameters specific to each tone generator can be 
controlled to produce tonal changes. Normally three types of 
control change data are sent: NRPN MSB (99), NRPN LSB 
(98), and Data Entry MSB (6). In the MOTIF XS, this group of 
control change events is handled as one. Once an NRPN is 
specified, the following data entry message received on the 
same channel is processed as the value of that NRPN. Prevent 
operational errors by transmitting an RPN Null message (7FH, 
7FH) after using these messages to perform a control 
operation. For filter cutoff frequency, resonance, and other 
independent control change parameters, it is normal to use 

the independent control change parameters rather than the 
NRPN.

n This MIDI event cannot be handled by the tone generator 

block, although it can be recorded to a Song/Pattern track. 

Changes internal tone generator settings such as Voice and 
effect settings, remote switch control, tone generator mode 
switching, and others via MIDI. The 2nd byte is a manufacturer 
ID number, and there is no data compatibility between 
manufacturers. This type of event is used to control MOTIF XS-
specific functions. The cursor can be used to scroll through 
the data if the data size is greater than 17 bytes.

As you use the MOTIF XS, you will create many different kinds of data, including Voices, Performances, Songs, and Patterns. 
This section describes how to maintain the various types of data and use the memory devices/media for storing them. 

Below are explanations of the basic terms related to 
memory. 

ROM (Read Only Memory) is memory designed 
specifically for reading out of data, and as such data 
cannot be written to it. Unlike conventional ROM, Flash 
ROM can be overwritten—allowing you to store your own 
original data. The contents of Flash ROM are maintained 
even when the power is turned off. 

RAM (Random Access Memory) is memory designed 
specifically for data writing and data reading operations. 
There are two different kinds of RAM, depending on the 
condition for storing the data: SRAM (Static RAM) and 
DRAM (Dynamic RAM). The MOTIF XS is equipped with 
only DRAM. The created data stored on DRAM is lost when 
the power is turned off. Because of this, you should always 
store any data residing in DRAM to the USB storage device 
or the computer connected to the network before turning 
off the power. 

n Among data residing in DRAM, only Waveform data can be 

saved to the external USB storage device or a computer 
mounted by the MOTIF XS. 

DIMM modules must be installed in order to use the 
Sampling function or to load audio data (Waveform/WAV 
file/AIFF file) to the instrument. As with DRAM described 
above, the created data stored on DIMM is lost when the 
power is turned off. Because of this, you should always 
store any data residing in DIMM to the USB storage device 
or the computer connected to the network before turning 
off the power. 

The edit buffer is the memory location for edited data of 
these types: Voice, Performance, Master, Song Mixing, and 
Pattern Mixing. Data edited in this location will be stored to 
the User Memory. 
If you select another Voice, Performance, Master, Song, or 
Pattern, the entire contents of the edit buffer will be 
rewritten with the newly selected Voice/Performance/
Master/Song Mixing/Pattern Mixing data. Make sure to 
store any important data before selecting another Voice, 
etc. 

If you’ve selected another Voice/Performance/Song/Pattern 
without storing the one you were editing, you can recall 
your original edits, since the edit buffer’s contents are 
stored in backup memory.

n Keep in mind that the recall buffer is not available in the 

Master Edit mode.
