Abstract: An electronic musical instrument having keys that include a first set of keys for generating program commands in real time such as chord and scale selections in response to being depressed, and a second set of keys for generating input device signals in response to being played. The electronic musical instrument also has a memory adapted to store a plurality of translation tables. The translation tables being adapted to translate the input device signals received from the second set of keys into corresponding control signals. A translator to the input device signals, the translation tables, and the program commands generating control signals which are used by an electronic signal generator. The electronic musical interface also includes an interface for providing access between the translator and at least one external device.

Abstract: An electronic musical instrument includes manual input devices such as keys, a memory device or devices such as CDs which contain a prerecorded musical signal, prerecorded translation tables, and a prerecorded series of translation table switching signals synchronized to events in the musical signal such as chord changes and scale changes, a translator responsive to the manual input devices, translation tables and translation table switching signals for generating control signals, and an electronic signal generator responsive to the control signals for generating audio signals determined by the control signals.
