The realization of multifunctional guitar effectors&synthesizer based on ADSP-BF533

This paper proposes a solution to design a new type of guitar effectors integrating a MIDI synthesizer function based on ADSP-BF533. The design proposal of the hardware system are introduced. The algorithm of the basic functions of guitar effectors such as distortion, equalization are introduced. An algorithm to synthesize MIDI, which is using STFT to detect the input note and send the involved information to the MIDI synthesize IC to synthesize the musical sound is proposed. In order to demonstrate our solution, the system has been designed. Experimental result shows that the system can be used as a MIDI synthesizer as well as a traditional guitar effectors.
