Patent ID: 7692090

Claim:
An electronic musical performance instrument comprising: a first modular control module comprising: a first musical instrument input interface manipulatable by a human operator; and a first control engine electronic circuitry being connected to the first musical instrument input interface, the first control engine electronic circuitry receives human operator input representations when the first musical instrument input interface is manipulated, the first control engine electronic circuitry provides an output that comprises a first manipulation representation in an electronic format; a second modular control module comprising: a second musical instrument input interface manipulatable by a human operator; and a second control engine electronic circuitry being connected to the second musical instrument input interface, the second control engine electronic circuitry receives human operator input representations when the second musical instrument input interface is manipulated, the second control engine electronic circuitry provides an output that comprises a second manipulation representation in the electronic format; the first control engine electronic circuitry and the second control engine electronic circuitry being interchangeable; and a motherboard adapted to run a general purpose computer operating system, the general purpose computer operating system being configured to enable the motherboard to run at least one user selected sound software packages to generate sound signals using the first manipulation representation and the second manipulation representation.
