 CONTROLLER Page 1 MODULATION (+), 2 MODULATION (-) The joystick can be used to modulate the parameters below as well as the pitch (vibrato). Here, you can set the degree to which the joystick modulates each of the following parameters. [2 ] FILTER Determines the degree to which the joystick modulates the Filter Cutoff Frequency. For details about the filter, see below. [3 ] AMPLITUDE Determines the degree to which the joystick modulates the amplitude (volume). [5 ] PMOD Determines the degree to which the joystick modulates the pitch, or the vibrato effect. [6 ] FMOD Determines the degree to which the joystick modulates the Filter modulation, or the wah effect. 1 [7 ] AMOD Determines the degree to which the joystick modulates the amplitude, or the tremolo effect. NOTE Make sure to assign the Modulation function to the joystick when using these effects (page 40). Voices  SOUND Page FILTER Filter is a processor that changes the timbre or tone of a sound by either blocking or passing a specific frequency range. The parameters below determine the overall timbre of the sound by boosting or cutting a certain frequency range. In addition to making the sound either brighter or mellower, Filter can be used to produce electronic, synthesizer-like effects. [1 ] BRIGHT. (Brightness) Determines the cutoff frequency or effective frequency range of the filter (see diagram). Higher values result in a brighter sound. Volume Cutoff Frequency [2 ] HARMO. (Harmonic Content) Determines the emphasis given to the cutoff frequency (resonance), set in BRIGHT. above (see diagram). Higher values result in a more pronounced effect. These frequencies are "passed" by the filter. Volume Cutoff range Frequency (pitch) Resonance Frequency (pitch) PSR-A3000 Owner's Manual 115
