Abstract: The evaluation system for evaluating a status of rumen fermentation in a ruminant includes an evaluation device that has an estimation unit for estimating a status of rumen fermentation in a ruminant based on a milk production record which indicates a milk yield and a milk component of milk produced by the ruminant. According to the evaluation system, it is possible to easily evaluate the status of rumen fermentation in the ruminant.

Abstract: A storage medium storing a musical performance program and a musical performance device are provided. A musical sound is output through a clicking operation performed on an operation button, and a tone parameter is changed through a dragging operation. A parameter display part 6a is displayed on the operation button. When the musical sound is output through a clicking operation performed on the operation button, a user can recognize a state of the tone parameter of the output musical sound in advance through the parameter display part. Since the tone parameter set through a dragging operation performed on the operation button is reflected to the parameter display part, the tone parameter is recognized without looking away from the operation button.

Abstract: A playback device configured to play back audio in response to an instruction. Prior to the instruction, decoded audio data corresponding to a header (e.g., frame number 1 to N) of compressed audio data may be stored in audio cache memory. After the instruction, the decoded audio data may be outputted while a frame number N of the compressed audio data is decoded to produce intermediate data for decoding frame number (N+1). Accordingly, decoded audio data corresponding to frame number (N+1) and subsequent frames may be played backed continuous from the frame number N. Thus, compressed audio data can be played back soon after an instruction.

Abstract: A media system for playing content on a media player with an electronic computing device for communication. When song title request information for a song title stored by a storage process is received from a computing device, song titles stored in the storage process are transmitted in a song title transmission process to the computing device, song selection information is received from the computing device, song performance information is read and the performance equipment runs a performance process from that performance information. When the performance equipment and the second communication process are run, the song titles are displayed on the display screen.
