CA501 MIDI Settings Manual
The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for connecting 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 instrument as a MIDI device, allowing the instrument to send and receive MIDI messages in the same manner 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 thedigital 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 torecord and playback performances using sequencer software
running on the computer. When multi-timbral mode is enabledon the digital piano, it becomes possible to record and playback
multi-track songs, with different sounds playing simultaneously
on each MIDI channel.
