Pitch Input (Configs 1, 4); Lfo Waveshape (Chorus Only); Lfo Speed (Chorus And Flange Only); Lfo Depth (Chorus And Flange Only) - Alesis GT Reference Manual

Pitch Input (configs 1, 4)

¥ Preamp Output The pitch module input signal comes from the
preamp output.
¥ EQ Output The pitch module input signal comes after the EQ
module.

LFO Waveshape (Chorus only)

As mentioned earlier, in chorusing the pitch change is cyclical. There are
two ways to modulate the pitch:
¥ Triangle This produces a smooth, regular chorusing sound.
¥ Square The time delay jumps between two values, producing a more
radical modulation effect.

LFO Speed (Chorus and Flange only)

The display says:
This parameter alters the rate of pitch modulation, from 01 (slow) to
(fast) 99.

LFO Depth (Chorus and Flange only)

The display says:
This parameter determines how much the modulation affects pitch. The
higher the number, the greater the degree of pitch modulation. High
LFO depth settings may make a signal seem out of tune unless you slow
down the LFO speed.
