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.

A system for modifying an audio signal comprises a computer including a first digital signal processor (DSP). The first DSP includes a first module and a second module. The first module is coupled to the interface to provide a musical instrument with a set of testing input signals and obtain a set of testing output signals from the musical instrument via the interface. The second module is configured to perform functions including: analyzing the set of testing output signals to obtain a set of parameters, constructing an acoustic transducer to model characteristics of the musical instrument based on the set of parameters, and receiving the audio signal to modify the audio signal using the acoustic transducer, wherein the first DSP module obtains the set of parameters at least by identifying occurrences when an output level state determined at least based on the set of testing output signals significantly changes.

A system for identifying a periodicity-related attribute in a multi-frequency signal. The system is configured to produce phase and delay modulated signals from a complex input signal. The system is designed to combine these phase and delay modulated signals to identify a periodicity-related attribute associated with the multi-frequency signal. The system is configured to produce a physically perceptible output based on the identified periodicity-related attribute.

A music generating system comprising sensors configured to acquire data sets related to physiological and environmental condition of a user and a computing device comprising a processor and a memory. The computing device is configured to read, by a data acquisition module, the data sets received from the sensors, to perform, by a data analysis module, a value range analysis of the data sets received to normalize the data sets, to map, with the help of the data analysis module, each of the normalized data sets to families of sounds stored in a data store, to create, by the data analysis module, individual music pieces on the basis of a time series analysis and a frequency analysis of the normalized data sets mapped to the families of sounds and to merge, by a music generation module, the individual music pieces to create a final piece of music.

A reproduction control method, which is executed by a computer, includes determining, based on an image showing an object, whether a type of the object is a first type or a second type that is different from the first type, and reproducing a sound, triggered by a striking of an operation surface by the object, based on a result of the determining.
