About MIDI
This section briefl y explains MIDI.
The term MIDI is an acronym for Musical Instrument Digital Interface, an international standard for connecting
keyboards, sequencers, and other MIDI devices so that they can exchange performance data. The CA piano is
equipped with three MIDI jacks for exchanging data:
MIDI IN, MIDI OUT and MIDI THRU. Each uses a special cable with a DIN connector.
MIDI IN : For receiving note, program change and other data.
MIDI OUT : For sending note, program change and other data.
MIDI THRU : For passing along MIDI data received to another MIDI device without processing.
MIDI uses channels to exchange data back and forth between MIDI devices. There are receive (MIDI IN) and
transmit (MIDI OUT) channels. Most musical instruments or devices with MIDI functions are equipped with both
MIDI IN and OUT jacks and are capable of transmitting and receiving data via MIDI. There are 16 MIDI channels
available to choose from on the CA piano. In addition to channel-to-channel connection, it is possible to receive
on multiple channels.
The receive channels are used to receive data from another MIDI device and the transmit channels are used to
transmit data to another MIDI device.
For example, if you were to connect three musical instruments together to play music:
Transmitting instrument
c
sends transmit channel and keyboard information to receiving instruments
d
and
e
.
The information arrives at the receiving instruments
d
and
e
. Receiving instruments
d
and
e
will respond to
MIDI data that is sent if their receive channel is the same the transmit channel of transmitting instrument
c
. If
the channels do not match, then the receiving instruments
d
and
e
will not respond to any data that is sent.
For both receiving and transmitting, channel 1 through channel 16 can be used.
