The keyboard applied to the cut-off frequency value. You can select which LFO will be used tracking can be used to compensate the cut-off frequency of the filter, as the modulation source in the VCF PARAMETERS menu. depending on the notes being played. When the cut-off frequency is modulated by the VCF LFO, each note will be affected by the shape and speed of the LFO. You can use this aggressively to create a wah pedal type effect, or use it subtly to add movement and variation to the program. When no LFO MODULATION is applied, the filter cut-off frequency will stay fixed (unless other sources of modulation are applied). It can prevent inconsistencies in the harmonic content caused by pitch changes. When the VCF KYBD fader is raised, the higher the note (above the middle C) played on the keyboard, then the more the filter opens. At the same time, the lower the note (below the middle C) played on the keyboard, then the more the filter closes. The cut-off frequency setting can limit the modulation from the LFO. If the VCF FREQ fader is already at its maximum setting, and the filter is already wide open, then no positive modulation can take the cut-off frequency higher. The VCF LFO range is from 0.0% to 100.0%, and the default setting is 0.0% (Off). The fader position, current value, and stored value for the VCF LFO fader is shown on the PROG screen. There is also a visualization of the LFO amount (the arrows pointing left and right below the LFO-2 text) as shown below: This modulation can be used to emulate the response of a natural instrument, or used to creative effect. The VCF KYBD range is from 0.0% to 100.0%, and the default setting is 0.0% (Off). The fader position, current value and stored value for the VCF KYBD fader is shown on the PROG screen. There is also a visualization of the modulation as a varying slope as shown below: Note: The distance between the arrows represents the amount of LFO modulation which is being applied to the filter cut-off frequency. Shortcut Note: To change the VCF LFO source quickly, press and hold the VCF EDIT switch. While holding the switch you can use the VCF LFO fader to select the source LFO-1 or LFO-2. The following message will be shown to give you guidance while holding the VCF EDIT switch: "Move LFO fader to set Source."
