Voice mode Performance mode Voice Edit mode Normal Voice Edit Element Edit EGDepth, Curve Cutoff Resonance [SF3] FEG (Filter Envelope Generator) Determines the velocity sensitivity of the FEG Level. For positive settings, the more strongly you play the keyboard, the more Filter changes the sound. Negative settings do the opposite; the more softly you play, the more the sound changes. The Curve parameter lets you select from five different preset velocity curves (graphically indicated in the display), that determine how velocity affects the Filter EG. Settings: EGDepth: -64 - 0 - +63 Settings: Curve: 0 - 4 Determines the degree to which velocity affects the Cutoff frequency of the Filter EG. For positive values, the more strongly you play the keys, the greater the change in the Cutoff frequency. Negative values do the opposite; the more softly you play, the greater the change in frequency. Settings: -64 - 0 - +63 Determines the degree to which velocity affects the Resonance of the Filter EG. For positive values, the more strongly you play the keys, the greater the Resonance change. Negative values do the opposite; the more softly you play, the greater the change in Resonance. Settings: -64 - 0 - +63 From this display you can make all the time and level settings for the Filter EG, which determine how the tonal quality of the sound changes over time. These can be used to control the change in Cutoff Frequency from the moment a note is pressed on the keyboard to the moment the sound stops. The full names of the available parameters are shown in the chart below, as they appear in the display.

From this display you can set the Key Follow effect for the Filter-in other words, how the tonal qualities of the Element and its Filter EG respond to the particular notes (or octave range) you play. Determines the degree to which the notes (specifically, their position or octave range) affect the Filter of the selected Element. A Center Key setting (next parameter) of C3 is used as the basic setting by the Cutoff parameter. A positive setting will lower the Cutoff frequency for lower notes and raise it for higher notes. A negative setting will have the opposite effect. Settings: -200 - 0 - +200 This indicates that the central note for Cutoff Sensitivity above is C3. At C3, the tone remains unchanged. For other notes played, the Cutoff Frequency varies according to the particular note and the Cutoff Sensitivity setting. Keep in mind that this is for display purposes only; the value cannot be changed. Settings: C -2 - G8 Determines the degree to which the notes (specifically, their position or octave range) affect the Filter EG times of the selected Element. The basic speed of change for the FEG is at the note specified in the Center Key (next parameter). A positive setting will cause slower changes for lower notes and faster changes for higher notes. A negative setting will have the opposite effect. Settings: -64 - 0 - +63 Determines the central note or pitch for the Key Follow effect on Filter EG. Depending on the EG Time Sensitivity parameter above, the further away from the Center Key the keys are played, the more the time of the Filter EG deviates from the normal. When the Center Key note is played, the FEG behaves according to its actual settings. The Filter change characteristics for other notes will vary in proportion to the EG Time settings. Settings: C -2 - G8 n You can also set the Center Key directly from the keyboard, by holding down the [INFORMATION] button and pressing the desired key.

You can divide the entire keyboard by four break points, and assign different offset values of Cutoff Frequency to them respectively. Refer to the setting example on page 169. Settings: BREAK POINT 1 - 4: C-2 - G8 OFFSET 1 - 4: 128 - 0 - +127 n You can also set the Break Point directly from the Keyboard, by holding down the [INFORMATION] button and pressing the desired key.
