■Equalizer (EQ)
Usually an equalizer is used to correct the sound output from 
amps or speakers to match the special character of the room, 
or to change the tonal character of the sound. The sound is 
divided into several frequency bands, and adjustments are 
made to the sound by raising or lowering the level of each 
band.
By adjusting the sound according to the genre—classical 
music being more refined, pop music more crisp, and rock 
music more dynamic—you can draw out the special 
characteristics of the music and make your per formance more 
enjoyable. 
Three separate EQ sections are available on the instrument: 
Element EQ, Part EQ, and Master EQ.
●Element EQ
The Element EQ is applied to each element of the Nor mal 
Voice and each key of the Drum Voice. You can specify which 
shape is used among the two shapes described below and 
set the related parameters. 
Peaking type
This type of EQ shape lets you attenuate/boost the signal at the 
specified Frequency setting.
Shelving type
This type of EQ shape lets you attenuate/boost the signal at 
frequencies above or below the specified Frequency setting.
nIn addition to the individual gain controls, there is also an overall 
level parameter that attenuates/boosts the entire frequency range.
●Part EQ
This 3-band EQ is applied to each par t of the Performance/
Song/Pattern, The high band and low band are the shelving 
type. The middle band is the peaking type. 
nThe part EQ is not available in the Voice mode. 
●Master EQ
Master EQ is applied to the final (post-effect), overall sound of 
the instrument. In this EQ, all bands can be set to peaking, or 
the lowest and highest bands can be set to shelving (as 
shown below).

Arpeggio
This function lets you automatically trigger musical and rhythmic phrases using the current Voice by simply pressing a note 
or notes on the keyboard. The Arpeggio sequence also changes in response to the actual notes or chords you play, giving 
you a wide variety of inspiring musical phrases and ideas—both in composing and performing.
nA single Arpeggio type can be played back at the same time even in the Performance, Song, and Pattern mode, enabling you to play multiple tone 
generator’s parts simultaneously. 
■Category of the Arpeggio type
The Arpeggio types are divided into 18 categories as listed below. 
LCDCategory NameDescription
SeqSynth Sequence Various arpeggio phrases suited for synth voices. 
ChSqSynth Chord Sequence Various rhythmic chord phrases or synth voices.
HySqSynth Hybrid Sequence Various arpeggio types programmed so that bass phrases ar e played with the lower keys and chor ds or 
melodies are played with the midrange and higher keys. These arpeggio types ar e useful for split voice 
combinations. In addition, ther e are also Hybrid Velocity (“HybVel...”) types that feature different phrases for 
different velocity ranges, letting you change the arpeggio phrase depending on how str ongly you play the 
keyboard.
APKbAcoustic Piano & Keyboard Various arpeggio types suited for piano and other keyboar d voices, such as electric piano and clav.
OrgnOrgan Various arpeggio types suited for organ voices. 
GtPl Guitar & Plucked Various arpeggio types suited for guitar and harp voices. 
GtKMGuitar—Keyboard Mega Voice Various arpeggio types suited for guitar Keyboar d Mega voices (see note below). 
BassBass Various arpeggio types suited for bass or synth bass voices. 
BaKM Bass—Keyboard Mega Voice Various arpeggio types suited for bass Keyboar d Mega voices (see note below). 
Strn Strings Various arpeggio types suited for strings and pizzicato voices. 
Bras Brass Various arpeggio types suited for brass voices. 
RdPp Reed & Pipe Various arpeggio types suited for saxophone and fl ute voices. 
Lead Synth Lead Various arpeggio types suited for synth lead voices. 
PdMeSynth Pad & Musical FX Various arpeggio types suited for synth pad voices and special musical ef fects voices, including percussive 
sounds.
CPrc Chromatic Percussion Various arpeggio types suited for chr omatic percussion voices. 
DrPc Drum & Percussion Various arpeggio types suited for drum and per cussion voices (drum kits). 
CombCombination Various arpeggio types suited for Per formances. These are combination arpeggios, with separate phrases 
suitable for drum voices, bass voices, and chor d/melody instruments. 
CntrControl Various arpeggio types programmed primarily with Contr ol Change and Pitch Bend data. These arpeggio 
types change the tone or pitch of the sound, rather than play specifi c notes. In fact, some types contain no 
note data at all. When using a type of this categor y, set the KeyMode parameter to “dir ect” in each mode.

■Arpeggio playback types
The MO features a total of 1787 Arpeggio types divided into 18 categories, each with its own playback type designed for 
use with particular types of Voices, as described below.
●Arpeggios for Normal Voices
Arpeggio types (belonging to the categories except for the DrPC and Cntr) cr eated for use of Normal Voices have the following two 
playback types. 
nThe two playback types above are not distinguished by the category name or type name. You’ll have to actually play the types and hear the difference.
nSince these types are programmed for Normal Voices, using them with Drum Voices may not give musically appropriate results.
●Arpeggios for Drum/Percussion Voices—Category: DrPc
These arpeggio types are programmed specifically for use with Drum Voices, giving you instant access to various rhythm patter ns. 
Three different playback types are available.
nThe three playback types above are not distinguished by the category name or type name. You’ll have to actually play the types and hear the 
difference.
nSince these types are programmed for Drum Voices, using them with Normal Voices may not give musically appropriate results.
●Arpeggios for Performances—Category: Comb
The Arpeggio types belonging to the categor y “Comb” are programmed so that different arpeggios are triggered—an arpeggio for 
a Normal Voice and an arpeggio for a Drum Voice—depending on the played note. These types are useful in the Performance 
mode in which multiple voices (Drum Voice and Normal Voice) are combined in a layer since these types enable you trigger the 
arpeggio for the Normal Voice and the Drum Voice at the same time. 
●Arpeggios containing mainly non-note events—Category: Cntr
These arpeggio types are programmed primarily with Control Change and Pitch Bend data. They are used to change the tone or 
pitch of the sound, rather than play specific notes. In fact, some types contain no note data at all. When using a type of this 
category, set the KeyMode parameter to “direct” with the following operations.
Playback only of the played notesThe Arpeggio is played back using only the played note and its octave notes. 
Playback of a programmed 
sequence according to the played 
chordThese Arpeggio types have the several sequences each of which is suited for a certain chord type. Even if you 
press only one note, the Arpeggio is played back using the programmed sequence—meaning that notes other 
than the ones you play may be sounded. Adding notes to those already held changes the sequence 
accordingly—in other words, the arpeggio plays back according to the chord you play.
Playback of a drum patternPressing any note(s) will trigger the same rhythm pattern. 
Playback of a drum pattern, plus 
additional played notes 
(assigned drum instruments)Pressing any note will trigger the same rhythm pattern. Adding notes to the one already held produces 
additional sounds (assigned drum instruments) for the drum pattern.
Playback only of the played notes 
(assigned drum instruments)Playing a note or notes will trigger a rhythm pattern using only the notes played (assigned drum instruments). 
Keep in mind that even if you play the same notes, the triggered rhythm pattern differs depending on the order 
of the notes played. This gives you access to different rhythm patterns using the same instruments simply by 
changing the order in which you play the notes.

Internal Memory and File Management
148Owner’s Manual
Internal Memory and File Management
As you use the MO, you’ll 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.
Maintaining data
You can maintain the data you’ve created via the following three methods. 
●Store
This is a process of transferring or saving the created data of this synthesizer to a dedicated location (User Memor y) in the internal 
memory. Each type of data can be stored with the following operations.
* Please note that pressing the [STORE] in the Utility mode starts the Store operation of the System settings immediately. 
Since Song Mixing, Pattern Mixing, and Mixing Voice data is stored to DRAM (page 150), all such data is lost when turning off the power—even if the 
data has been stored with the operations above. Make sure to save this data to the USB storage device in the File mode after storing. 
Never attempt to turn off the power while data (e.g., Voice) is being written to Flash ROM (while an “Executing...” or “Please keep power on” message 
is shown). Turning the power off in this state may cause the system to freeze (due to corruption of data in the Flash ROM) and prevent normal startup 
the next time the power is turned on, as well as resulting in the loss of all user data.
This is a process of transferring or saving the created data of this synthesizer to an exter nal memory device (USB storage device). 
This process can be done in the File mode. The Save operation can be done via various methods, such as saving all data as a 
single file or saving a specified type of data (e.g., only Voices) as a single file. For details, see Memory Structure (page 149) and 
Reference (page 211). The saved data as files can be recalled by loading them in the File mode. 
●Bulk Dump
This function lets you save the data in the Edit buffer (DRAM) or Flash ROM by transmitting it as Bulk data (system exclusive 
message) to an external MIDI instrument or sequence software on a computer. This can be done with the following operations.
nMixing Voice data cannot be transmitted as Bulk data via panel operations.
nUser Arpeggio data and some of the System settings are not handled as Bulk data. 
nThe data in the User Memory of Flash ROM can be transmitted to an external MIDI instrument or computer upon reception of a bulk request message. 
For details about the bulk request message and bulk dump format, see the separate Data List. 
Using the Voice Editor and Multi Part Editor
Voice data can be transmitted to a computer for editing with the Voice Editor software (page 112). The edited Voice on the 
instrument itself data can then be transmitted back to the instrument in banks as bulk data. Similarly, Voice data created in 
the Voice Edit mode can be sent to the computer in banks as bulk data.
Mixing data can also be transmitted to a computer for editing, using the Multi Part Editor software (page 112). The edited 
Mixing data can then be transmitted back to the instrument as bulk data. Mixing data created in the Mixing Edit mode on the 
instrument itself can also be sent to the computer in banks as bulk data.

Internal Memory and File Management
150Owner’s Manual
Internal Memory
Below are explanations of the basic terms used in the Memory Structure illustration on the previous page.
● Flash ROM
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. 
● DRAM
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 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 before turning off the power.
● Edit Buffer and User Memory
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. 
● Edit Buffer and Recall Buffer
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. 
nKeep in mind that the recall buffer is not available in the Master Edit mode.
