• LFO 1 - Shape & Amount

This screen controls the waveshape and amount of Low Frequency

Oscillator 1. The LFO can be used to produce vibrato (when routed to

pitch), or tremolo (when routed to volume). The LFO can be routed to

control any of the Realtime Modulation destinations (page 123). The

five LFO waveshapes are: Triangle, Sine, Square, Sawtooth, and Ran-

dom. The amount can be varied from -128 to +127. Negative values will

produce inverted waveshapes.

• LFO 1 - Rate, Delay & Variation

This screen controls the rate, delay and variation of LFO 1.

LFO Rate

Varies the LFO speed from 0.052 Hz to 25 Hz (000-127).

LFO Delay

Sets the amount of time between hitting a key and the onset of

modulation. This can be used to simulate an effect often used by

acoustic instrument players, where the vibrato is brought in only

after the initial note pitch has been established. The delay range is

variable from 0 to 13 seconds (000-127).

LFO Variation

Sets the amount of random variation of an LFO each time a key is

pressed. This function is useful for ensemble effects, where each

note played has a slightly different modulation rate. The higher

the number, the greater the note to note variation in LFO rate.

LFO variation is variable from 000-127.
