Abstract
An electronic musical instrument, which includes an internal tone generator, a local-on play function, which produces musical tones in consonance with tone data generated by the internal tone generator, and a local-off play function, which externally outputs only an MIDI signal without performing tone production in consonance with tone data generated by the internal tone generator. The instrument comprises first tone information storage for, when the local-on play function is selected, storing a channel that corresponds to tone data, which are generated by the internal tone generator, for each of the tone data; tone-on channel assigning circuitry for employing the tone information, which are stored in the first storage, to specify a channel that corresponds to the tone data generated by the internal tone generator; a further tone generator, which is connected to the tone channel assigning circuitry, for producing a musical tone in consonance with the tone data from the tone-on channel assigning circuitry; second tone information storage for, when the local-off play function is selected, successively storing the ON/OFF states of tone data generated by the internal tone generator for each set of the tone data; a local-off tone data control for employing the tone information stored in the second tone information storage to output, as tone data for an MIDI signal, the tone data that is generated by the internal tone generator without performing either tone channel assignment or tone production for the tone data; and a MIDI signal output, which is connected to the tone channel assigning circuitry and the local-off tone data control, for outputting, as MIDI signals, tone data from the tone channel assigning circuitry and tone data from the local-off tone data control.
