A method and system provides for a wide range of temporospatial patterns of electrical stimulation waveforms to be readily specified for respective channels of a multichannel cochlear prosthesis. The cochlear prosthesis includes: a speech processor system, and a cochlear stimulator. The speech processor system typically includes an external headpiece, including a microphone, coupled to a speech processor. The speech processor includes electronic circuitry, typically including a microprocessor, that converts acoustical signals sensed through the microphone to electrical signals, and processes the electrical signals in accordance with a desired speech processing strategy. The definition of simple or complex stimulation waveforms to be used as part of the selected speech processing strategy is facilitated, in a preferred embodiment, through the use of a template table stored in the speech processor. The rows and columns of the template table define time intervals and stimulation channels (and hence stimulation sites). The individual cells of the template table are programmed, e.g., using a laptop computer, to contain selected alphanumeric codes or characters, including null characters, that define the polarity and relative magnitude of desired stimulation patterns and waveforms that are applied to the defined stimulation sites at the indicated frame times. Alternatively, the stimulation patterns and waveforms may be specified in a list of spatial/temporal events.
