How do I edit the K2000 and K2500(without KDFX) FX presets?
The K2000 and K2500 (without KDFX) have a built-in effects processor from Digitech Corporation, a manufacturer of high-quality professional signal processors. In the K2, the effects processor can use up to 4 simultaneous effects including: reverb, stereo chorus, stereo delay, EQ, and many others. Add the stereo effects processor to the powerful per channel DSP and you've got tremendous flexibility.
For this tutorial we'll use Program 62 Gospel Organ as our basic starting point.
From the PROGRAM mode, enter 62 + ENTER on the keypad. Press the EFFECTS button and let's look at the display. You will see EFFECT, where you select effect programs, WET/DRY MIX which controls the balance between the effected and dry signal, and FX MODE which allows you to specify the manner in which the effect processor is being used.
There are several possible FX MODE choices:
Below the FX MODE is FX CHANNEL (you can select which MIDI channel the effect processor responds to for receiving program changes). You can instruct the effects processor to receive program changes from an external MIDI source such as a sequencer or alternate controller. You may hard assign one specific MIDI channel for this purpose, or select CURRENT, allowing program changes on any channel to automatically change the associated effect program.
Let's call up the Effect # 109 Chorus Delay, which we'll be using for this exercise. Highlight the EFFECT parameter and scroll using your alpha wheel until you come to 109 Chorus Delay. Set the Wet/Dry mix to 50%, set the FX MODE to MASTER and the FX CHANNEL to CURRENT. Use the cursor and alpha wheel to highlight and alter specific parameters. Play to confirm that you are using Prog #62 Gospel Organ and effect #109, which is a kind of chorus and delay program. (You'll notice that if you move the modulation wheel and listen, the rotary speaker effect will change speeds, speeding up and slowing down. This effect is not created by the multi effects processor, but rather by the K2's LFOs. There is a Rotary Speaker effect program where you could also create a similar effect.)
Let's edit the Chorus Delay Effect. Highlight the EFFECT parameter (#109 Chorus Delay) and press EDIT. Take note of all of the parameters you can edit. Look for a moment at the top highlighted bar showing you the effect algorithm: EQ, CHORUS, 4 TAP DELAY, and MIXER. Let's look at some of the other algorithms by pressing the up or down CHAN /BANK - Layer/Zone button and see the descriptions change. Each algorithm has its own set of parameters which you can edit. Take a moment to edit some of the parameters, play and listen to the changes. Return to the EQ+Cho+4TAP+MIX algorithm and stop. Notice the familiar NAME, SAVE, DELETE and DUMP functions. Let's highlight LFO SPEED and DEPTH and try some variations. Use your cursor to highlight specific fields and your alpha wheel to change the parameter settings. Play to hear the changes. Remember, you can have up to 100 effects programs in memory at any one time, depending on how much user memory you have.
