1: LFO
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.

VOICE EDIT MODE / 5:LFO
Wave (LFO waveform)
Range: tri, dwn, up, squ, sin, S/H
Controls: [CS2], [-1] [+1], Dial
Determines the waveform of the LFO.
“tri” = Triangle. “dwn” = Downward sawtooth.
“up” = Upward sawtooth. “squ” = Square.
“sin” = Sine. “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.
