Synthesizer Controls
These four controls allow you to modify the selected program. Turning a
knob sets the parameter to the current knob position. Select the program
again to restore the original setting.
Cutoff � Controls the low pass filter cutoff frequency. Turning the control
up allows more high frequencies to pass. Turning the control down reduces
high frequencies.
Resonance � Resonance or “Q” boosts the frequencies around the cutoff
frequency. This gives the filter a sharper and more synthesizer-like sound.
Attack � When a key is pressed, the low pass filter cutoff is turned up at a
rate specified by this control (if edited). Turning the control up increases the
attack time.
Decay/Release � This control specifies the time it takes for the low pass
filter to close down after a key is released (and depending on the selected
program, after the attack time).
Effects Controls
The Chorus and Reverb effects add effects are applied to
all programs and to both sides of a split keyboard.
Chorus � This effect thickens the sound as it makes one
voice sound like many. The knob controls the chorus
depth or “how much” chorus is applied.
Reverb � Reverberation is a simulation of a natural space
such as a room or hall. This knob controls the reverb
amount.
