PC2 Made Easy

18. Effects Editing

Each Program and Setup in the PC2 can have its own effects settings. With the FX Mode

parameter set to its default settings, when you call up any individual program from the

front panel, you will hear the effects assigned to that program. And when you go to

MIDI Setups mode, you will hear the effects assigned to that setup instead of the effects

assigned to the individual programs called up in that Setup. (If you are sequencing and

playing several programs at a time then only one program can be in control of the effects

Ð more on this in tutorial #30.

You can customize the effects for programs in the User banks as well as the preset

banks. You do not need to save a program to the User bank in order to change and save

the effects for one of the presets.

We already covered choosing the FX bus and setting the wet/dry mix in the Basic

Concepts section. We will be covering changing and editing the effects themselves in this

tutorial.

1. Start in Internal Voices Mode and call up program 17 Serious Classic. Notice that the

FX-A button is lit. This electric piano program uses a simple hall reverb. Play the

program to hear what it sounds like.

2. Press the wet/dry button. Notice that A is set to 10%. Change this to 75% and play

the program. The reverb is much wetter. We are going to keep the wet/dry level set this

high so as we make changes, they will be quite noticeable.

3. Now press the FX-A Select button. The display shows the current effect is Grandiose

Hall. Change it to Effect #151, Sweet Flange. Play the keyboard and notice the

difference in the sound. The simplest form of effects editing is to change the overall

effect. There are several different flange effects. Try switching through all the effects

between 150 and 155, playing the keyboard after each change to hear the difference.

Then set it back to #151.

4. Once you have chosen the effect you want, you can make further changes. Each effect

will have up to 4 parameters that you can edit. Press the >> button. The first parameter

is LFO Period and its value is 10 bts (beats). Press >> again to see LFO Tempo, which is

set to 120BPM.

Flanging is the process of taking a signal, duplicating it and displacing the duplicated

signal in time, and the adding or subtracting the two signals together. This gives you a

series of notches in the frequency spectrum, generally referred to as a comb filter. The

end result is a classic sound that most people recognize.

The 2 LFO parameters are related to each other. An LFO is used to sweep the two

signals back and forth, creating the flanging effect. You set the amount of time it takes to

sweep back and forth based on a tempo and the number of 1/4 note beats for that

tempo.

Change the LFO Tempo to 60 BPM and play some notes. Then try setting it to 180 BPM

and play some notes again to hear the difference.
