What is a Control
Processor?
There are two kinds of signals in a modular analog
synthesizer: audio and control. As audio signals go through a system of
synthesizer modules, they get shaped into the sounds that you hear. Control
signals, on the other hand, correspond to the variations in the sound that are
imparted by the synthesizer modules, like invisible hands that turn the knobs of
the modules. The CP-251 gives you a bank of control signals and lots of ways to
modify, mix, and distribute them to product the myriad dynamic effects that
analog synthesizers are famous for.
Power supply is included: order
110v for use in US or Canada or 220v for use in Europe, Asia, South America, and
Australia.
CP-251 Control Signal Functions
- FOUR INPUT MIXER - Enables you to combine control signals to create complex
effects.
- LAG PROCESSOR - Reshapes control signals by slowing down abrupt changes,
used to produce glides and swoops.
- LOW FREQUENCY OSCILLATOR (LFO) - Makes periodic control signals over the
range of one cycle every five seconds to 50 cycles per second. The LFO is
itself voltage-controlled so you can vary its rate with an expression pedal or
other control signal to create effects such as vibrato, warbles, and sirens.
- TWO ATTENUATORS - To reduce the strength of control signals,
enabling you to adjust the strength of an effect.
- FOUR-WAY MULTIPLE - Enables you to send one control signal to as many as three
destinations.
- NOISE SOURCE - Provides pure noise for use as an audio or control signal.
- SAMPLE AND HOLD - Produces stepwise
control signals by sampling the voltage of any signal at rate of the LFO to
produce classic sample-and-hold effects. This circuit also has a second output
which is a smoothed version of the stepwise output.
