1: LFO [VOICE] → [EDIT] → [MENU] → 5:LFO → [ENTER/YES] → [ENTER/YES] → → [MENU] → 1:LFO → [ENTER/YES] These parameters define the operation of the SY85's main LFO (Low Frequency Oscillator). The main LFO controls amplitude, pitch, frequency, and filter cutoff modulation applied via the modulation wheel, the foot controller, and keyboard aftertouch response.

"tri" = Triangle. "up" = Upward sawtooth. "sin" = Sine. "dwn" = Downward sawtooth. "squ" = Square. "S/H" = Sample and hold. Sped (LFO speed) Range: 0 ... 99 Controls: [CS3], [-1] [+1], Dial Sets the speed of the LFO. "0" is the slowest Speed setting, producing an LFO speed of approximately 0 Hertz. The fastest setting of 99 produces an LFO speed of approximately 25 Hertz. Pmod (Pitch modulation depth) Range: 0 ... 127 Controls: [CS4], [-1] [+1], Dial Sets the maximum amount of pitch modulation that can be applied to the current voice. A "0" setting produces no modulation while a setting of "127" produces maximum modulation. Pitch modulation produces a periodic pitch variation, thereby creating a vibrato effect. Please note that the pitch modulation depth parameter for the controller which is to be used to apply pitch modulation (see page 83, 85, and 87) must also be set to an appropriate value before pitch modulation can be applied. 78 VOICE EDIT MODE / 5:LFO
