Patent ID: 7122731

Claim:
A reproduction switching device for use in a musical information processing terminal which is capable of receiving performance data that represents musical tones in a predetermined format and audio data that represents audio waveforms from an external musical information processing terminal via a communication network, comprising: a first switching device that gives a switching instruction for selecting data to be reproduced either from the performance data or from the audio data; a receiving device that receives the performance data or the audio data from the external musical information processing terminal; a data determining device that determines which type of data, performance data or audio data, said receiving device has received; a second switching device that gives a switching instruction for specifying whether or not a result of determination by said data determining device should be made effective; a setting device that sets either the performance data or the audio data having been selected by said first switching device, as the data to be reproduced, when said second switching device has given the switching instruction specifying that the result of determination by said data determining device should not be made effective, and sets, on the basis of the type of data having been determined by said data determining device, either the performance data or the audio data, as the data to be reproduced, when said second switching device has given the switching instruction specifying that the result of determination by said data determining device should be made effective; and a reproducing device that reproduces data having been set by said setting device, as the data to be reproduced, from among either the performance data or the audio data that has been received by said receiving device.
