Synthesizer Mode
J Tone Characteristic Waveform
z Tone Setting
Specifies which of the preset tones should be used as the
original tone.
J Volume Characteristic Parameters
These parameters control how the tone changes over time,
from when the keyboard key is pressed until the tone decays.
You can specify changes in volume and sound characteristics.
z Attack time
This is the rate or time it takes for the tone to reach its highest
volume level. You can specify a fast rate, where the tone
reaches its highest volume level immediately, a slow rate
where it gradually rises, or something in between.
z Release time
z Cutoff Frequency
The cutoff frequency is a parameter for adjusting timbre by
cutting any frequency that is higher than a specific frequency.
A larger cutoff frequency produces a brighter (harder) timbre,
while a smaller frequency produces a darker (softer) timbre.
z Resonance
Resonance enhances the harmonic components in the vicinity
of the cutoff frequency, which creates a distinctive sound. A
larger resonance value enhances the sound as shown in the
figure.
With some tones, a large resonance value can cause
distortion or noise during the attack part of the tone.
J Tone Pitch Parameters
z Vibrato Type, Vibrato Delay, Vibrato Rate, Vibrato Depth
These parameters adjust the vibrato effect, which causes
periodic changes in the tone.
z Octave Shift
This parameter controls the octave of all tones.
J Tone Characteristic Setting Parameters
z Level
This parameter controls the overall volume of the tone.
z Touch Sense
This parameter controls changes in volume and timbre in
accordance with the relative amount of pressure applied to
the keyboard keys. You can specify more volume for stronger
pressure and less volume or a lighter pressure, or you can
specify the same volume regardless of how much pressure is
applied to the keys.
z Reverb Send, Chorus Send, DSP Line , DSP Type, DSP
Parameter
These parameters control the effects applied to tones.
