Suggestions on using AMS
When making settings for alternate modulation, think of the
effect that you wish to produce, what type of modulation will
be necessary to produce that effect, and what parameter of
the oscillator, filter, or amplifier needs to be controlled.
Next, select a source (
AMS
) and set the
Intensity
. If you
proceed logically in this way, you will achieve the desired
effect.
For example, if you want to control a guitar sound so that it
approaches feedback when you move the joystick, you might
set up the joystick to modulate the filter frequency and
resonance.
Controller Setup page
For each program, PROGRAM > Basic/X-Y/Controllers–
Controllers page lets you make settings for the SW1 and
SW2 key, and for RT control knobs 1–6. For more
information, see “SW1 and SW2” on page 29, and “1–8:
Controllers,” on page 48 of the PG.
Controlling Pitch
Parameters for controlling pitch are located on the
OSC/Pitch page, as shown below.
Pitch bend
The
JS (+X)
and
JS(–X)
settings specify the amount of pitch
change (in semitones) that will occur when MIDI pitch bend
messages are received or when the joystick is moved to left
or right. A setting of
+12
allows the pitch to be controlled a
maximum of one octave upward; a setting of
–12
allows the
pitch to be controlled a maximum of one octave downward.
Creating Vibrato
You can use an LFO to create vibrato.
LFO 1/2 Intensity
sets the depth to which the selected LFO
will affect the pitch. With a setting of
+12.00
, vibrato will
produce a maximum of ±1 octave of pitch change.
JS+Y Int
specifies the amount of vibrato that the LFO will
produce when the joystick is pushed away from yourself.
Intensity
(AMS Intensity) specifies the depth of vibrato that
will be applied by the LFO when modulated by the selected
AMS (Alternate Modulation Source). For example, if
LFO1
AMS
is set to After Touch and you set an appropriate value
for
Intensity
, vibrato will be applied when MIDI aftertouch
messages are received.
As another example, if
SW1
is set to
SW1 Mod. (CC#80)
on the Set Up Controllers page,
LFO1 AMS
is set to
SW1Mod. (CC#80)
, and the
AMS Intensity
is set to an
appropriate value, vibrato is applied when you turn on
SW1
or when MIDI CC#80 is received.
Pitch EG
When the
Intensity
value is set to
+12.00
, the pitch EG
specified in the Pitch EG page will produce a maximum of
±1 octave of pitch change.
To realistically simulate the slight change in pitch that
occurs when a string is plucked or at the attack of a brass or
vocal sound, you can use the EG to create a subtle change in
pitch at the attack.
Portamento
Portamento makes the pitch change smoothly when you play
the next note before releasing the previous note.
The
Time
parameter controls how long it take the pitch to
change. As this value is increased, the pitch will change over
a longer time. With a value of
000
, there will be no
portamento.
You can turn Portamento on and off via SW1 or SW2, by
assigning them to
Porta.SW CC#65.
