Effects Programmed in the Preset

Decay Time

This parameter sets the length of time it will take an effect to fade away. In the case of reverb, decay time controls the room size and the reflectivity of the room. On a delay effect, decay time controls how many echoes are produced or how long the echoes will last.

v To Change the Decay Time:

1.Press the Preset Edit button. The LED illuminates and the Preset Edit screen which was last used appears.

2.Press the Global function key (F3). The Preset Globals menu appears.

3.Press the Next page button. The Effects A menu appears.

4.Move the cursor to the Decay Time field using the cursor buttons.

5.Set the Decay Time using the Data Entry Control, or INC/DEC buttons.

6.Press the Exit button to return to the main screen.

HF Damping

High frequency energy tends to fade away first as a sound is dissipated in a room. This parameter allows you adjust the amount of high frequency damping and thus change the characteristics of the room. Rooms with smooth, hard surfaces are more reflective and have less high frequency damping. Rooms filled with sound absorbing materials such as curtains or people have more high frequency damping.

v To Change the High Frequency Damping:

1.Press the Preset Edit button. The LED illuminates and the Preset Edit screen which was last used appears.

2.Press the Global function key (F3). The Preset Globals menu appears.

3.Press the Next page button. The Effects A menu appears.

4.Move the cursor to the HF Damping field using the cursor buttons.

5.Adjust the HF Damping parameter using the Data Entry Control, or INC/DEC buttons.

6.Press the Exit button to return to the main screen.

FX Amounts

The Effects Amount controls the percentage of effected (wet) signal to uneffected (dry) signal. This function would be analogous to the effect sends on a mixing console. The effects amount for each of the four stereo outputs can be individually controlled.

v To Change the Effects Amount:

1.Press the Preset Edit button. The LED illuminates and the Preset Edit screen which was last used appears.

2.Press the Global function key (F3). The Preset Globals menu appears.

3.Press the Next page button. The Effects A menu appears.

4.Move the cursor to the desired FX Amount field using the cursor buttons.

5.Adjust the FX Amount using the Data Entry Control, or INC/DEC buttons.

6.Press the Exit button to return to the main screen.

FX B Through FX A

The output of effect processor B can be routed into effect processor A. This connects the effects in series instead of their normal parallel configuration. The BflA amount can also be controlled for even more flexibility.

v To Send the Output of Effect B through Effect A:

In this example, 100% of Effect B will be sent into Effect A.

1.The Effect A screen (in either the Master or Preset Edit menus) contains the B–>A Amount parameter. Set this amount to 100%.

2.Turn the Send Amounts down to zero since we only want to hear the two effects in series.

3.Press the Next page button to select Effect B. Select an effect and adjust the Main FX B Send percentage as desired.

4.Play the keyboard and you should hear the B Effect running through Effect A.

Preset Effects B

Preset Effects B

The Preset Effects settings are normally used whenever you are in Omni or Poly mode. This allows the effects to be programmed as part of the preset. Because there are only two effects processors for the entire machine, effects cannot be programmed separately for each preset in Multimode.

If the Effect parameter is set to “Master Effect B”, the effects settings in the Master module are used and the parameters in the Preset Effects become unavailable. This system allows the effects to be assigned per preset or globally for all presets. “B” type effects consist manly of chorus, flange and digital delay effects.

The Preset Effects B can be accessed from the Preset Global submenu by pressing the Next button twice.

Effect B

This function selects the type of effect used. The following effects are currently available:

Effect B

Feedback Amount

The Chorus and Flange effects have a controllable feedback loop after the delay element. Feeding back a small amount of the signal intensifies the effect by creating multiple cancellations or images.

v To Change the Feedback Amount:

1.Press the Preset Edit button. The LED illuminates and the Preset Edit screen which was last used appears.

2.Press the Global function key (F3). The Preset Globals menu appears.

3.Press the Next page button twice. The Effects B menu appears.

4.Move the cursor to the desired Feedback Amount field using the cursor buttons.

5.Adjust the Feedback Amount using the Data Entry Control, or INC/ DEC buttons.

6.Press the Exit button to return to the main screen.

Effect B

LFO Rate

Chorus and flange effects use a Low Frequency Oscillator to animate the effect. LFO applied to a chorus effect creates the slight changes necessary for a realistic choral effect. Applied to a flanger, the LFO moves the comb filter notches and adds animation to the sound.

v To Change the LFO Rate:

1.Press the Preset Edit button. The LED illuminates and the Preset Edit screen which was last used appears.

2.Press the Global function key (F3). The Preset Globals menu appears.

3.Press the Next page key twice. The Effects B menu appears.

4.Move the cursor to the LFO Rate field using the cursor buttons.

5.Set the LFO Rate using the Data Entry Control, or INC/DEC buttons.

6.Press the Exit button to return to the main screen.

Delay Time

Flanging, chorus and echoes are all based on a delay line where the signal is delayed by some time period and mixed back together with it's un-delayed signal. This parameter varies the length of the delay or “how much time” passes before you hear the delayed signal. On some effects, this parameter is not adjustable, indicated by a dash in the field.

v To Change the Delay Time:

1.Press the Master button. The LED illuminates and the Memory Statistics screen appears.

2.Press the Output function key (F4). The Output menu appears.

3.Press the Next page button twice. The Effects B menu appears.

4.Move the cursor to Delay Time using the cursor buttons.

5.Adjust the Delay Time parameter using the Data Entry Control, or INC/DEC buttons.

6.Press Exit to return to the main screen.
