## Abstract

In an electronic musical instrument, an input device inputs performance information. A tone generator operates based on tone setting parameters for generating music sounds according to the performance information. A display is capable of switching a plurality of scenes for displaying either of the performance information or tone setting parameters. An image data generation part creates one or a plurality of print image data representing contents of the plurality of the scenes upon detecting a print instruction operation. An interface is provided in the electronic musical instrument to output the print image data directly to an external printer for printing out the contents of the scenes.

## Claims

### Claim 1

An electronic musical instrument comprising:
an input device that inputs performance information, wherein the input device includes one or more operators for inputting either of setting operation for setting the electronic musical instrument or performance operation;
a tone generator that generates music sounds according to the performance information and setting parameters, wherein the tone generator generates music sounds in response to the performance operation;
an image data generating part that generates image data representing either of the performance information or the setting parameters;
an interface directly connectable to an external printer for outputting the image data to the external printer;
an acquisition part that acquires an image data format printable by the external printer;
a recording part that records a log, which is at least one of a history of operations of the operators or a transition of the setting state of the electronic musical instrument based on a sequence of setting operations by the operators, the recorded log listing at least internal state transitions upon startup of the electronic musical instrument, internal state transitions in printer initialization process, reception of the performance information from an external equipment, reception of the performance information from an external equipment, reception of setting information and transitions of the setting state of the electronic musical instrument due to the setting information,
wherein the image data generating part generates image data representing the recorded log in the acquired image data format; and
a print instruction part that transmits the generated image data to the external printer through the interface to print the log according to the generated image data.

### Claim 2 (depends on 1)

The electronic musical instrument according to claim 1, further comprising a reception part that receives the performance information for use in the tone generator to generate the music sounds according to the received performance information and that receives the setting information for use in setting of the various parts of the electronic musical instrument from external equipment.
