Provided is an electronic musical instrument system. A PC is configured to perform an operation of emulating an analog synthesizer by a first software synthesizer. The PC installs a second software synthesizer to a hardware synthesizer on condition that the hardware synthesizer is confirmed to be the device corresponding to the second software synthesizer. The hardware synthesizer performs the operation of emulating the analog synthesizer by the second software synthesizer. The first software synthesizer and the second software synthesizer related to the operation of emulating the analog synthesizer have the same function respectively, and are capable of generating the same tone respectively, the effect of reproducing the same function and tone as the synthesizer that is to be emulated can be achieved respectively in two different devices, i.e. the PC and the hardware synthesizer.

Electronic musical instrument system

A tuning device is provided. The sound to be tuned is inputted by an input means while a reference sound is produced by an output means. At least two pitches are detected independently from a mixture of the sound to be tuned and the reference sound by a pitch detection means. Based on pitch information of the reference sound acquired by an acquiring means, the pitch of the sound to be tuned is extracted by a pitch extraction means from the at least two pitches detected by the pitch detection means. Information about the pitch of the sound to be tuned is displayed by a display means under control of a display control means. Therefore, the user can easily perform tuning on the sound to be tuned, based on the pitch information displayed by the display means, while listening to the reference sound and producing the sound to be tuned.

Tuning device

A tuning device is provided for properly tuning two sounds that are produced simultaneously. According to the invention, a notification means is provided for notifying the user of information about a relative pitch difference value of a first pitch corresponding to a first pitch name and a second pitch corresponding to a second pitch name, which are among the pitches detected by a pitch detection means. Through the notification of the notification means, the user can check the relative pitch difference value of the two sounds that is displayed by a pitch name display means to properly tune the two sounds that are produced simultaneously.

A tuning device that facilitates the checking of the pitch of each sound is provided. The tuning device includes a pitch name display means including display positions that are arranged in a pitch order respectively corresponding to pitch names constituting an octave. A reference display position is lighted solely when the pitch of an input sound is in an in-tune state, namely, a difference between the reference pitch and the pitch of the input sound is in a range of &#xb1;&#x3b1; (&#x3b1;&#x3e;0). When the pitch of the input sound is outside a predetermined range, the reference display position and an adjacent display position are both lighted in a way that the reference display position gradually becomes darker while the adjacent display position gradually becomes brighter as an absolute value of the difference (deviation degree of the input pitch relative to the reference pitch) increases.
