LFO's square wave output. Turn the ATTENUATOR knob back and forth. Note that the

shape of the effect is determined by the signal that is fed to the ATTENUATOR's input,

and the amount or intensity of the effect is determined by the setting of the

ATTENUATOR knob. This is generally true for all control signal sources and all control

destinations on voltage-controlled devices.

Now we'll illustrate a patch that uses both attenuators.

• Connect more patch cords as follows:

a) from the OUT jack of the second ATTENUATOR, to the PEDAL IN of the LFO.

b) Plug the expression pedal into the IN jack of the second ATTENUATOR.

Set the second ATTENUATOR knob to about "9 o'clock". Now the first ATTENUATOR knob

is varying the strength of the LFO control signal, and the second ATTENUATOR knob is

varying the amount that the expression pedal is changing the LFO rate.

FOUR-INPUT MIXER

A MIXER combines, or adds together, two or more signals. Your CP251's Four-Input

Mixer has four input jacks, labeled 1 through 4. Inputs 1 and 2 have input attenuator

knobs, while inputs 3 and 4 are mixed in without attenuation. The OFFSET knob raises or

lowers the voltage of the mix, while the MASTER knob determines the amplitude of the

entire mix. There are two output jacks, labeled "+" and "-". The "- "output is the negative

of the "+" output. That is, the voltage at the "-" output goes down when the voltage at

the "+" output goes up, and vice versa.

•Connect patch cords as follows:

a) from the LFO triangular output to MIXER input 1,

b) from the LFO square output to MIXER input 2,

c) from the MIXER "+" output to the VCTG pitch control input.
