Reference Voice mode Voice Edit mode • CutoffSens (Cutoff Sensitivity) Determines the degree to which the notes (specifically, their position or octave range) affect the Filter of the selected element. A Center Key setting 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% • CenterKey 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. Amount of cutoff + frequency change Large Small Lower range - Center(basic frequency) Higher range • EGTimeSens (EG Time Sensitivity) 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 • CenterKey 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 norm. 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 Positive value + Speed of FEG level change Lower range Higher range Basic frequency Negative value + Speed of FEG level range Lower range Higher range Basic frequency n You can also set the Center Key directly from the keyboard, by holding down the [INFORMATION] button and pressing the desired key. See "Basic Operation" on page 75. 144 MOTIF Reference ● [F3]-[SF5] Normal Element Filter Scaling Filter Scaling controls the filter cutoff frequency according to the positions of the notes on the keyboard. You can divide the entire keyboard by four break points, and assign different offset values of Cutoff Frequency to them respectively. • BREAK POINT 1 ~ 4 ❏ Settings C -2 ~ G8 n You can also set the Break Point directly from the Keyboard, by holding down the [INFORMATION] button and pressing the desired key. See "Basic Operation" on page 75. • OFFSET 1 ~ 4 ❏ Settings -128 ~ 0 ~ +127 The best way to understand Filter Scaling is by example. For the settings shown in the example display above, the basic Cutoff frequency value is 64, and the various Offset values at the selected Break point settings change that basic value accordingly. The specific changes to the Cutoff frequency are shown in the diagram below. The Cutoff frequency changes in a linear fashion between successive Break Points as shown. Cutoff Frequency 74 81 68 60 Note C#1 D#2 C3 A4 Break Point 1 Break Point 2 Break Point 3 Break Point 4 n BP1 to BP4 will be automatically be arranged in ascending order across the keyboard. n Regardless of the size of these Offsets, the minimum and maximum Cutoff limits (values of 0 and 127, respectively) cannot be exceeded. n Any note played below the BP1 note results in the BP1 Level setting. Likewise, any note played above the BP4 note results in the BP4 Level setting.
