Abstract
A MIDI Controller has the capability to automatically randomize, on multiple MIDI channels, four key elements of sound, namely timbre, pitch, volume, and dynamic response, to produce new total sounds. The MIDI Controller includes a user configurable randomizer which can selectively randomize the four key sound elements through processor operators. The randomizer includes a random number generator, the output of which is selectively truncated depending upon the particular element being randomized.

In a MIDI Controller which produces MIDI commands for controlling sound generation by one or more MIDI sound generators from note inputs and switch inputs, the improvement comprising:
- randomizer means selectively connected to said one or more MIDI sound generators and reponsive to said note inputs and switch inputs for randomizing timbre and one or more of the following sound elements of a MIDI command produced by said MIDI controller:
- pitch, volume and dynamic response.
A MIDI Controller for controlling the total sound produced by a plurality of MIDI sound generators connected to and controlled by the MIDI Controller, comprising:
- note input means for providing note inputs;
- switch input means for providing switch inputs;
- element memory means for storing a plurality of master programs;
- a sound change event command buffer for storing event commands;
- scanner means for generating the event commands based on contents of the element memory upon occurrence of changes in the note inputs and switch inputs, the scanner means writing the event commands to the event buffer;
- processor means for reading event commands from the event buffer and converting the event commands into MIDI commands;
- and
- randomizer means coupled to said processor for facilitating selective randomization of timbre and at least one of the following elements:
- pitch, volume and dynamic response.

- a sound generation system for generating said designed audible total sound from said plurality of composite sounds;
- a plurality of sound signal generators, each said sound signal generator generating a signal representing one of said plurality of composite sounds, each of said plurality of composite sounds having a particular timbre and a plurality of sound elements;
- and
- a user-activated randomizer coupled to said plurality of sound signal generators for randomly selecting a random timbre from a plurality of possible timbres.
A method of designing an audible total sound on an electronic sound designing system, said total sound comprising a plurality of composite sounds, each of said plurality of composite sounds comprising a plurality of sound elements including timbre, pitch and dynamic response, each of said plurality of sound elements having a plurality of variations, said electronic sound designing system comprising a sound generator associated with each of said plurality of composite sounds, a plurality of note inputs, a randomizer for randomizing one or more of said plurality of sound elements comprising a given composite sound, a memory for storing information representing said plurality of variations of said plurality of sound elements, said electronic sound designing system operating in accordance with conventional Musical Instrument Digital Interface (MIDI) standards, said method comprising:
- activating a sound generator;
- activating said randomizer to randomly choose a sound element variation of at least one of said plurality of sound elements comprising said composite sound associated with said activated sound generator;
- inputting one of said plurality of note inputs, whereby a total sound including said at least one randomized sound element is produced;
- and
- generating to said total sound.
An electronic sound designing system for designing and generating an audible total sound comprising a plurality of composite sounds, said electronic sound designing system operating in accordance with conventional Musical Instrument Digital Interface (MIDI) standards, comprising:
- a sound generation system comprising an amplifier and a speaker for generating said designed audible total sound from said plurality of composite sounds;
- a plurality of sound signal generators, each of said plurality of sound signal generators being capable of generating one of said plurality of composite sounds, each of said plurality of composite sounds having a particular timbre, pitch, volume and dynamic response;
- a data source for generating data representing timbre, pitch, volume and dynamic response, said data source comprising a user-activated randomizer for randomly selecting a random timbre and one or more random sound elements from a group comprising pitch, volume and dynamic response, said random timbre and one or more random sound elements being selected from a plurality of possible timbres, pitch levels, volume levels and dynamic responses.
