The Lfo Menu: Rotor Effects Parameters - Kurzweil PC2 - MUSICIANS GUIDE REV A Manual

Descriptions of Parameters
Program Editor Parameters
Adjusting the values of the LFO parameters modiÞes how the LFOs affect the programs that use
them (not all programs make use of the LFOs). See MIDI Controllers on page B-9 to learn which
programs have functioning LFOs.
Many programs use LFO1, which is always local, meaning that the LFO affects just one layer of
the program. The other LFO is called LFO2 in some programs, and GLFO in others. LFO2 is
always local, while GLFO is global, which means that it uniformly affects every layer in the
programs that use it. In other words, if you change the value of a GLFO parameter in one layer,
that value remains constant regardless of which layer you select while editing the program. The
detailed description of the LFO parameters begins on page 5-3.
LFO1 Rate
The number of oscillation cycles per second (Hz) for LFO1. Changing the value makes the LFO
run faster or slower.
LFO1 Shape
The waveform of the oscillation. Changing the value changes the nature of the LFOÕs effect on
the sound.
LFO2/GLFO Rate
The number of oscillation cycles per second (Hz). Changing the value makes the LFO run faster
or slower.
LFO2/GLFO Shape
The waveform of the oscillation. Changing the value changes the nature of the LFOÕs effect on
the sound.

The LFO Menu: Rotor Effects Parameters

The rotor effects simulate the popular Leslie rotating speaker that has become a standard
addition to the B-3 organ. The KB3 effects all use rotor effects. You can add rotor effects to other
programs by saving one of the KB3 effects to those programs.
The rotor effects have two pairs of parameters. Each is responsible for emulating the two
speakers (high and low frequencies) that make up the original Leslie rotating speaker.
Rotor Effects Low Rate
Oscillation cycles per second (Hz) for the low rotor. Negative values reverse the phase without
changing the rate.
Rotor Effects Low Adjust
The amount of change in the rate of the low rotor when you switch the rotorÕs speed control
from fast to slow or vice versa. KB3 programs use SW1 to switch rotor speed.
Rotor Effects High Rate
Oscillation cycles per second for the high rotor. Negative values reverse the phase without
changing the rate.
