Because there is only one effects processor in the K2000, you can only have one effect (or multiple effect such as Chorus plus Reverb)called up at a time. You have a choice as to whether or not you want to route a program or a layer in a program through the effects processor, but you can't have different effects for each layer or program. The two parameters, FX Mode and FX Channel (found on the Effects Mode Page), are important to understand because they determine how the effects processor is controlled.

You use the FX Mode parameter to choose what will control the effects processor. The default value is Auto. This means that whichever Mode you are currently in is controlling the effects. Each program and setup has an effect assigned to it. So if you go to Program mode and call up a program, the effect assigned to the program on the effects page in the program editor will be called up. For example, if you go to program mode, call up number 1, 3rd World Order and then go back to the Effects mode, you will see that the effect is Flange Tap. Of you go back to Program Mode, call up number 2, Stereo Grand Piano, and go back to Effects, you will see Warm Room. The same would apply for Setups. You assign an effect to a program on the EFFECT page in the Program Editor. For a setup, it is assigned in the Setup Editor.

The FX Mode parameter works in conjunction with the FX Channel. The default value for this is Current. This means that the program assigned to the MIDI channel currently in the display is in control of the effects. But you can also set this to a specific channel. For example, you could set it so that the Program on Channel 1 is in control of the effects. Then no matter how you switch the display, the effects processor will always be controlled by whatever program is currently on channel 1.

As we mentioned, in Auto, either a Program or a Setup can be in control, depending on which mode you are in. You can also set this parameter to Setup or Program only. The final value is Master. When set to Master, the effect that you call up on the Effects Mode page will be the one you hear, no matter what program you call up. In this situation, the FX channel becomes the channel you would use to send program changes on to call up effects or send real-time controller changes. You can also use this channel to send controllers to alter parameters in real time. For most people using an external sequencer, Master will often be the most practical setting to use.

If you are using the K2000's sequencer, there are a couple of options you can take. If you set FX Mode to Master, you can choose your effect on the Effects page and it will remain at that setting . If you put it in Auto and the FXChan on Current, then you will have use of the Effect Channel parameter which is found on the Edit Common page of the song. In this case, which ever program is on the Effect Channel will be controlling the effects.

All of this is can get a little confusing. We suggest you review this information in the manual to make sure you have a clear understanding of these concepts.
