Abstract

A system and method for processing and generating control signals for the real-time controlling of signal processors, synthesizers, musical instruments, MIDI processors, lighting, video, and special effects in performance, recording, and composition environments. The invention provides for the use of incoming control signals to control events and parameters of low-frequency oscillators and transient generators. The invention also provides for the processing of control signal values such as addition, multiplication, mirroring, offset, etc., individually or in combination with one another. The invention further provides for the conversion of one type of control signal to another type of control signal, for example conversion of MIDI “not-on message” parameters such as note number and velocity into MIDI “continuous controller messages” etc. The invention is particularly directed towards, but not limited to, the processing and generation of control signals in the form of MIDI messages.

a low frequency oscillator

a transient generator

wherein the at least one incoming control signal is used to control events and parameters associated with the at least one control signal generator.

3. The system of claim 1 wherein all control signals are in the form of MIDI messages.

2. A method for the generation of real-time control signals based on at least one incoming control signal, the system utilizing at least one control signal generator of one of the following types:

a low frequency oscillator

a transient generator

wherein the at least one incoming control signal is used to control events and parameters associated with the at least one control signal generator.

4. The method of claim 2 wherein all control signals employ the form of MIDI messages.

5. A method for the processing of real-time control signals based on at least one incoming control signal, the system utilizing at least one control signal processor of one of the following types:

a numerical operation on the value of the control signal;

a numerical operation on the value of at least two control signals, wherein the at least one incoming control signal is used to create at least one new control signal.

6. The method of claim 5 wherein all control signals employ the form of MIDI messages.
