Interactive music application apparatus and electronic musical instrument and programs therefor

A program embodied on a device readable medium and executable by a processor for controlling an operating condition of a music application in a music application apparatus interactively operable by being connected with an electronic musical instrument, said program comprising:

• a transmission/reception step of transmitting a predetermined identification request signal to the electronic musical instrument connected with the music application apparatus and receiving a response signal returned by the connected electronic musical instrument in response to the predetermined identification request signal;
• a determination step of determining, on the basis of the response signal received by said transmission/reception step, whether or not the connected electronic musical instrument is of a predetermined identity;
• and
• a step of causing the music application to progress normally in response to performance-operator-operation-related information given by the connected electronic musical instrument when said determination step has determined that the connected electronic musical instrument is of the predetermined identity, but causes the music application to progress only in a limited function mode when said determination step has not determined that the connected electronic musical instrument is of the predetermined identity.

A program embodied on a device readable medium and executable by a processor for controlling an operating condition of a music application in an electronic musical instrument interactively operable by being connected with a music application apparatus, said program comprising:

• a step of receiving a predetermined identification request signal from the music application apparatus;
• and
• a step of returning a response signal indicative of a preset identity of the electronic musical instrument to the music application apparatus,
• wherein the preset identity of the electronic musical instrument as indicated by the response signal is an essential condition for determining whether the music application shall progress normally on the music application apparatus or whether it shall progress in a limited function mode.
