A8: LFO SPEED

Permits setting the speed of the low frequency oscillator. The data range is from 0 to 99. 0 corresponds to the slowest LFO speed (0.06 Hz), and 99 corresponds to the fastest LFO speed (50 Hz).

A9: LFO DELAY

Permits setting a delay of between 0 and approximately 3 seconds before the LFO modulation effect begins after a key is played. This is particularly useful for simulating brass instruments, human voice, etc., in which the a vibrato effect is gradually applied after the note has been initiated.

The data range is from 0 to 99. At 0 there is no delay, and a setting of 99 produces a delay of approximately 15 seconds. With longer delay settings the modulation effect begins gradually for a remarkably natural sound.

A10: LFO PMD

This parameter sets the depth of pitch variation produced by LFO modulation for all operators simultaneously. This function is independent from pitch modulation produced by the modulation wheel and breath controller, and is always ON once set.

The data range is from 0 to 99. At 0 pitch modulation is OFF, and a setting of 99 produces the greatest pitch variation, dependent on the PITCH MODULATION SENSITIVITY setting, described below (A13). When the PITCH MODULATION SENSITIVITY parameter is set to maximum (7), the maximum pitch variation (PM DEPTH = 99) will be plus and minus 1 octave.

Even if this parameter is set to 0, pitch modulation can still be applied via the modulation wheel or breath controller.

A11: LFO AMD

This parameter sets the depth of amplitude variation (tremolo or wow) produced by LFO modulation for all operators simultaneously. This function is independent from amplitude modulation produced by the modulation wheel or breath controller, and is always ON once set.

The data range is from 0 to 99. At 0 amplitude modulation is OFF, and a setting of 99 produces the greatest variation, dependent on the AMPLITUDE MODULATION SENSITIVITY setting (A14). When the AMPLITUDE MODULATION SENSITIVITY parameter is set to maximum (3), the maximum amplitude variation (AM DEPTH = 99) will be plus and minus 42 dB peak-to-peak.

Even if this parameter is set to 0, amplitude modulation can still be applied via the modulation wheel and breath controller.
