The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for con-
necting musical instruments, computers, and other devices to allow the exchange of performance data.
When the instrument is connected to a computer using a USB cable, the computer will recognise the in-
strument as a MIDI device, allowing the instrument to send and receive MIDI messages in the same man-
ner as a normal MIDI interface.
Use a suitable USB cable to connect the USB type A port on the computer to the USB type B port on the
digital piano. If there is no USB type A port on the computer, a conversion adapter may be required.

MIDI use case
When connected to a computer, the digital piano can be used to
record and playback performances using sequencer software
running on the computer. When multi-timbral mode is enabled
on the digital piano, it becomes possible to record and playback
multi-track songs, with different sounds playing simultaneously
on each MIDI channel.
