Within setup mode you can use the 4th EDIT CONTROL to decide how the FX2000's effects combinations (presets 61-71) should be structured. Since the FX2000 is a true Dual Engine unit, you can choose between serial 1 ("SER1"), serial 2 ("SER2") and parallel ("PARA").

In the example of preset 61 (chorus & reverb), you can decide whether the chorus and reverb effects run separately from each other or whether the signal treated by the chorus also passes the reverb effect.    

FX Combinations include: Chorus & Reverb Flanger & Reverb Leslie & Reverb Pitch & Reverb Delay & Reverb Tremolo & Reverb Phaser & Reverb Chorus & Delay Flanger & Delay Pitch & Delay Tremolo & Delay
