[. . . ] This gives breadth or fatness to the sound by applying modulation to the waveform (only to Square) in the internal sound module. end PWM Rate (Pulse Width Modulation Rate) *2 0­100 A higher value will quicken the rate of the modulation. 47 Chapter 4 Introduction to Effects and Parameters Parameter/ Range 0­100 Explanation Parameter/ Range Explanation PWM Depth (Pulse Width Modulation Depth) *2 Adjusts the depth of the PWM. When it is set to "0, " no PWM effect is obtained. Synth Level 0­100 Adjusts the volume of the synthesizer sound. Adjusts the volume of the direct sound. Cutoff Frequency 0­100 Adjusts the frequency where the harmonics contents of the sound are cut off. Adjusts how much of the harmonics contents around the cutoff frequency should be emphasized. Adjusts the sensitivity of the filter. Direct Level 0­100 Resonance 0­100 *1 Parameter setting included when Wave is set to "Square" or "Saw. " *2 Parameter setting included when Wave is set to "Square. " Filter Sens 0­100 When it is set to a lower value, the filter is affected only with stronger picking. When it is set higher, the filter changes even with weaker picking. When it is set to "0, " the depth of the filter will be the same no matter how the picking strength may be. AC (Acoustic Processor) This processor allows you to change the sound produced by the pickup on an acoustic electric guitar, creating a richer sound similar to that obtained with a microphone placed close to the guitar. Parameter/ Range Explanation Filter Decay 0­100 This sets the time needed for the filter to finish its sweep. Adjusts the depth of the filter. Filter Depth -100­+100 When the value is higher, the filter will change more drastically. The polarity of the filter will be opposite with "+" and "-. " Type Small, Medium, Bright, Power Selects the modeling type. Attack Decay, 0­100 Adjusts the time needed for a synthesizer sound to reach its maximum. Small This is the sound of a small-bodied acoustic guitar. When it is set to a lower value, the sound will rise quickly. When it is set higher, the sound will rise slowly. When it is set to "Decay, " the sound will rise quickly and turn to a Release status regardless of the input of the guitar sound. * When "Brass" or "Bow" is selected for the wave, the attack time will not be quicker from a certain level even if the attack is set to "Decay" or "0. " Medium This is a standard, unadorned acoustic guitar sound. Bright This is a bright acoustic guitar sound. Power This is a powerful acoustic guitar sound. Release 0­100 This determines the time needed for the synthesizer sound to reach zero from the moment the input of the guitar sound is completed. Bass -50­+50 Adjusts the low-end balance. Specifies the frequency range to be adjusted with Middle. Adjusts the balance in the extended upper range. Adjusts the volume. Middle -50­+50 Middle Freq 20. 0 Hz­10. 0 kHz * When "Brass" or "Bow" is selected for the wave, the guitar signal itself is processed. That is, the synthesizer sound will go down when the guitar signal goes down no matter how long the release may be set. Velocity 0­100 This adjusts the amount of the volume change of the synthesizer sound. Treble -50­+50 Presence -50­+50 When it is set to high, the volume change will be greater depending on the picking strength. When it is set to "0, " no volume change is caused even by changing the picking manner. Level 0­100 Hold *1 Off, On The hold function can sustain the output of the synthesizer sound. If you turn on the hold while a synthesizer sound is being output, the synthesizer sound will be held until you turn it off. * It is assumed that this parameter will be assigned (p. 57) to the foot switch. 48 Chapter 4 Introduction to Effects and Parameters SH (Sound Hold) You can have sound played on the guitar be held continuously. This effect allows you to perform the melody in the upper registers while holding a note in the lower registers. * This function will not work properly when two or more notes are played simultaneously.
