MIDI Connections
This section explains how to connect the A3000 to MIDI devices.
Important
Be sure that power to the A3000 and to peripheral devices is OFF before making MIDI
connections. Connecting devices while power is ON may result in MIDI processing er-
rors or unexpected and continuous sound output.
About MIDI
The following overview introduces some basic MIDI concepts. Readers familiar with
MIDI may wish to skip to “MIDI Connection Configurations,” on the next page.
What is MIDI?
MIDI (for “Musical Instrument Digital Interface”) is a standard, internationally-recog-
nized interface for music-related digital communication among electronic instruments,
computers, sequencers, and related devices.
MIDI connectors and cables
MIDI devices provide MIDI connectors marked IN, OUT, and THRU. The IN connector
receives data from external devices, the OUT connector outputs locally produced data,
and the THRU connector relays data received at the IN connector. MIDI connections are
made by running standard MIDI cables between connectors on different devices. Each
MIDI cable connects the OUT or THRU connector of one device to the IN connector of
another device.
Channels
A single MIDI cable carries up to 16 channels of performance data. If you have a MIDI
setup consisting of three keyboards outputting performance data to a fourth device, for
example, each keyboard would be transmitting data over a different channel. Each channel
is identified by its channel number (1 to 16).
