Makeup Tools (Styles and SMF)
Velocity
This parameter allows you to modify the velocity range of the
instrument in question. “0” means that the recorded velocity values
are left untouched, negative values reduce all velocity values by
the same amount (leaving dierences between notes intact), while
positive settings increase all velocity values.
Parameter Value
Velocity -127–+127
Cut O
This lter parameter allows you to make the selected sound darker or
brighter. Positive settings mean that more overtones are allowed to
pass, so that the sound becomes brighter. The further this value is set
in the negative direction, the fewer overtones will be allowed to pass
and the sound will become softer (darker).
Setting
Characteristics of a low-pass lter
Cuto frequency
Frequency
Parameter Value
Cut O -127–+127
NOTE
For some sounds, positive (+) “Cut O” settings will cause no
noticeable change because the preprogrammed “Cut O”
parameter is already set to its maximum value.
Resonance
This is a parameter one invariably associates with a synthesizer. When
the “Resonance” value is increased, the overtones in the area of the
cuto frequency will be emphasized, creating a sound with a strong
character.
Parameter Value
Resonance -127–+127
NOTE
For some sounds, negative (–) “Resonance” settings may
produce no noticeable change because the resonance is already
set to the minimum value.
The following parameters allow you to set the sound’s “envelope.”
The envelope parameters aect both the volume (TVA) and the lter
(TVF). The cuto frequency will rise as the envelope rises and fall as
the envelope falls.
Attack (T)
This parameter adjusts the onset of the sound. Negative values
speed up the attack, so that the sound becomes more aggressive.
Parameter Value
Attack -127–+127
Decay (T)
This parameter adjusts the time over which the sound’s volume and
cuto frequency fall from the highest point of the attack down to the
sustain level.
Parameter Value
Decay -127–+127
NOTE
Percussive sounds usually have a sustain level of “0.” Piano and
guitar sounds are in this category. Holding the keys for a long
time will have little eect on the duration of the notes you are
playing, even if you select a high value here.
Release (T)
This parameter adjusts the time over which the sound will decay
after the note is released until it is no longer heard. The cuto
frequency will also fall according to this setting.
Parameter Value
Release -127–+127
Use the following three parameters if you think the instrument in
question has too much (or could use a little more) vibrato.
NOTE
Some sounds already contain natural (sampled) vibrato whose
depth or speed cannot be changed.
Vibrato Rate (T)
This parameter adjusts the speed of the pitch modulation. Positive
(+) settings make the preset pitch modulation faster, and negative (–)
settings make it slower.
Parameter Value
Vibrato Rate -127–+127
Vibrato Depth (T)
This parameter adjusts the intensity of the pitch modulation. Positive
(+) settings mean that the “wobble” becomes more prominent,
while negative (–) settings make it shallower.
Parameter Value
Vibrato Depth -127–+127
Vibrato Delay (T)
This parameter adjusts the time required for the vibrato eect to
begin. Positive (+) settings increase the time before vibrato will begin
and negative settings (–) shorten the time.
Parameter Value
Vibrato Delay -127–+127
Mfx
The E-A7 contains 2 multi-eects processors (“Mfx”), one reverb
processor and one chorus processor that can be used to process
styles or Standard MIDI Files.
Select “O” for instruments that don’t need to be processed by any
Mfx.
Parameter Value
Mfx O, A, B
NOTE
If you select “A” or “ B ,” additional parameters can be edited (see
below).
Mfx Type
Allows you to select the desired Mfx type, i.e. the kind of eect
you need. Each Mfx (“A” and “B”) can be assigned to as many
instruments as you like. Be aware, however, that selecting a dierent
type will aect all instruments that use this Mfx processor. See page
13 for a list of the available Mfx types.
NOTE
While the “Mfx” parameter is set to “O,” you cannot select a
dierent type. In that case, the display will show the message
“---.”
