Turning on the power on recalls the last used memorized effect and activates play mode automatically. 2 INPUT level adjustment knob Turn the knob to the left or right to adjust the input level.
~ Understanding the Signal Flow This unit takes in audio signals from two types of input jacks (digital and analog), processes them using various internal blocks, and outputs them through the analog and digital output jacks. To make the most of this unit, it is essential that you have a firm understanding of the audio signal flow.
U1 Analog IN/OUT and digitaliN/OUT This unit is provided with both analog and digital inputs and outputs, and you can use both of tilt'm at the same time. The input block in the SYSTEM: Setup menu lets you determine whether to usc the anall'g, the digital, or both the analog and the digital INPUT /OUTPUT jacks.
en Hooking Up 12EN • Before connecting this unit to another device, be sure to unplug the AC power cord from the power outlet. • Turn off the power switch on this unit and all components to be connected, such as keyboards and active speakers (speakers with built in amplifiers).
........ Choosing an Effect Recalling Effects from the Memory The effector comes with 198 different effects stored in the preset memory as well as a 198 effect memory capacity for storing the effects you create. You can use the following procedure to select effects from either the preset memory or the user memory banks.
ex> Choosing an Effect Morphing . When the structure is set to (MORPH) (see page 8 for details on the system structure, see page 19 to change the structure), the effector creates a seamless change between effects when you switch to other memory numbers whose structures are also set to (MORPH).
(.C Processing Effects (EDIT) 5 18 fN Turn the operation dial to choose the setting you desire. i Operation dial To change numerical values Use the number buttons and ENTER to input the value you want dire(,tly. If you press the wrong number, input the number again before pressing ENTER.
o Processing Effects (EDIT) . Editing in PLAY Mode (direct edit) With direct edit you can edit up to6 different parameters directly from th .. PLA Y scre<>n. TI,<'S€ parameters are called Active Parameters. The following steps show you how to edit from the play screen once you've designated the Active Parameters.
Saving Processed Effects (SAVE) Saving an Effect Effects created by changing the parameter values with the edit function can be stored in one of the two USER memory banks for later use.
I'.;) Setting the System Environment In the system mode lets you set up the effector's operating environments. To go back to the previous screen during setup, press EXIT once. To return to the play mode after making adjustments, press EXIT a few times until you reach the PLAY screen.
CA) Using MIDI You can use the MIDI interface to control various aspects of this unit For example, you can switch between memorized effects by using the program table, or save USER memory data onto an external storage device. In addition, MIDI controls, like wheels and velocity effect .
