A sound-creation interface is used to create a sound-creation instrument such as a musical instrument. The musical instrument includes a mechanical-human interface such as a set of keys, strings or breathing pipe for user actuation and control of the system, a mechanical-electrical interface receiving inputs from the mechanical-human interface and for converting those inputs to a machine comprehensible signal and an electrical/processor interface receiving signals from the mechanical electrical interface and converting those signals into a processor comprehensible form. A processor receives processor comprehensible signals from the electrical-processor interface and includes a processor component and a memory component. The system allows simplified interaction between the user using the mechanical interface and the processor providing an improved sound-creation interface.
