ABSTRACT:
A music apparatus is constructed for introducing a music sound into an acoustic space, and is equipped with an acoustic feedback system for introducing a reflection sound into the acoustic space. In the music apparatus, an input device sequentially provides performance information. A sound source generates a music signal representative of the music sound in response to the performance information provided from the input device. A plurality of channels of the acoustic feedback system are provided in the music apparatus, and are spatially separate from each other. Each channel is structured by a microphone for collecting a sound from the acoustic space to produce a sound signal representative of the sound introduced into the acoustic space, a processor for processing the sound signal to generate a reflection signal representative of a reflection sound in the acoustic space, a mixer for mixing the reflection signal and the music signal with each other to form a mix signal, and a loudspeaker for acoustically reproducing the mix signal to introduce the music sound and the reflection sound into the acoustic space.
