● Filter
This unit modifies the tone of the sound output from Pitch by 
cutting the output of a specific frequency portion of the sound.
Cutoff Frequency and Resonance
Here’s how filters work.  In the example below (a low pass 
filter), a portion of the signal lower than a given frequency is 
allowed to pass, and signals above that frequency are cut. 
This frequency is referred to as the cutoff frequency. You can 
produce a relatively...

● Amplitude
This unit controls the output level (amplitude) of the sound 
output from Filter. The signals are then sent at this level to the 
Effect block. Also, by setting the AEG (Amplitude Envelope 
Generator), you can control how the volume changes over time. 
AEG (Amplitude Envelope Generator)
Using the AEG, you can control the transition in volume from 
the moment the sound starts is to the moment the sound 
stops. You can...

Part structure of the tone generator block
This synthesizer plays the sounds in the tone generator block in 
response to MIDI messages received from the controller or 
sequencer block. The MIDI messages are assigned to sixteen 
independent channels, and this synthesizer is capable of 
simultaneously playing sixteen separate parts, via the sixteen 
MIDI channels. However, the sixteen-channel limit can be 
overcome by using separate...

■ Part structure of the tone generator block in the Song mode/Pattern mode
In these modes, multiple parts are provided and different voice and different melodies or phrases can be played back for each 
part. Because these modes let you set the MIDI channel for each part of the tone generator block, you can use an external MIDI 
sequencer as well as the sequencer block of the instrument to play the sounds.
As illustrated below, the...

Audio Input Part (AUDIO IN)
The Performance mode, Song mode, and Pattern mode are capable of handling the audio input signal as a Part. Various 
parameters such as volume, pan, and effect can be set to this Part and the sound is output together with other Parts. Other 
available settings include how stereo input signals are handled, as well the output assignment of the audio Part.  
These parameters are set and stored for each...

■ Song data structure
The following illustration shows the track structure of a Song. Songs are created by recording MIDI sequence data to individual 
tracks and by setting tone generator related parameters (in Song Mixing).
● Song Mixing
Even if you record your keyboard performance to a Song 
track, the setup data (non-note events such as voice, pan, 
volume) which for proper playback should be recorded at the 
top of the Song will...

■ Pattern data structure
The following illustration shows the track structure of a Pattern. Patterns are created by recording MIDI sequence data to 
individual tracks, by assigning Phrases (Preset and User) which is material for a Pattern to individual tracks, and by setting tone 
generator related parameters (in a Pattern Mixing).
● Pattern Mixing
Even if you record your keyboard performance to a Pattern 
track, the setup data...

● Pattern Chain
Pattern Chain allows you to string several different Sections 
(within a single Pattern) together to make a single Song. You 
can have the synthesizer automatically change Sections by 
creating Pattern Chains in this way beforehand. 
You can create the Pattern Chain by recording a Pattern 
playback with Section changes from the [PATTERN] → [F6] 
CHAIN display or by editing the timing of Section changes 
from the...

● Punch In/Out (Song)
You can use this method when you want to re-record only over a specific area of the track. You’ll need to set the start and end 
points before re-recording.
In the eight-measure example below, the third measures through the fifth measure are re-recorded.
nPunch In/Out Recording can only be used with Realtime recording.
nNote that the Punch In/Out method always replaces (destroys) the original data over the specified...

■ Arpeggio playback types
The MOTIF ES 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) created for use of Normal Voices have the following 
two playback types. 
nThe two playback types above are not...
