A music playing system includes a computer and user interface to access a media database. A wireless base station device has a line out port providing two channel output. An automatic player piano has analog MIDI inputs, and a piano keyboard mechanism. The computer communicates wirelessly with the base station device, and the line out of the base station device outputs two channels which are connected to the analog MIDI inputs. A musical work, including related audio and MIDI data codes, is stored in the media database, with the different data codes in association with two different channels. The music data is sent via the wireless base station to the corresponding inputs of the piano. The piano sound system produces sound from the audio data codes and sends actuation signals to the keyboard mechanism, based on the MIDI codes.
