Music output switching device, musical output switching method, computer program for switching musical output

摘要

An optimal transmission state of musical tone information is realized in a multi-timbral state where a plurality of different musical tones can be output or input simultaneously and a non-multi-timbral state where a single musical tone is output or input. When the non-multi-timbral state is selected (step 12), the zones “1” and “2” are set to the internal communication state (INT), and the zones “3” and “4” are set to the external communication state (EXT). When this is done (step 12), all zones / tones are set to both states (BOTH) (step 13). In both states, both the above-described inner communication state and outer communication state are executed simultaneously. In the external communication state, the musical sound information is transmitted to the external device connected to the musical sound device (internal device), and in the internal communication state, the musical sound information is transmitted only in the musical sound device (internal device).
