Using the EF-303 with External MIDI Devices
What is MIDI?
MIDI (Musical Instrument Digital Interface) is a standard
that allows performances and other data to be exchanged
between electronic musical instruments and computers. Data
can be transmitted and received if a MIDI cable is used to
connect devices that have MIDI connectors. Virtually all
electronic musical instruments today are equipped with
MIDI. Without using MIDI, an external keyboard cannot be
used to play the EF-303, or the step modulator of the EF-303
used to play an external sound module. Although the EF-303
can be used without knowing very much about MIDI, this
chapter provides a simple explanation of the EF-303's MIDI
functionality so that you can take the fullest advantage of
electronic musical instruments.
The EF-303 can receive MIDI performance data to operate its
effects, or play back MIDI musical data.
About MIDI connectors
The EF-303 has two MIDI connectors
MIDI OUT connector
MIDI messages are transmitted from this connector to
external MIDI devices. MIDI messages received from MIDI
IN can also be re-transmitted without change from this
connector.

MIDI transmit/receive settings (TX/RX) (p. 55)
MIDI IN connector
MIDI messages from external MIDI devices are received at
this connector. When the EF-303 receives MIDI messages, it
can produce sounds or switch settings.

About MIDI channels
MIDI transmits performance data for up to sixteen musical
parts over a single MIDI cable. This is made possible by MIDI
channels. By using MIDI channels, the receiving device is
able to choose from the large amount of incoming data, and
use only the data that it needs. There are sixteen MIDI
channels, numbered 1 through 16, and messages are received
i
1
when the MIDI channels of the transmitting and receiving
devices match.
On the EF-303 you can select one of these sixteen channels.

MIDI data flow inside the EF-303
MIDI data flows inside the EF-303 as follows.
EF-303
The device that transmits tempo data and start/stop
messages is called the "master," and the device that
synchronizes to this data is called the "slave."
Applications/connections when using
external MIDI devices
Playing the EF-303 as an
external sound module
MIDI note messages can be transmitted from an external
MIDI sequencer or keyboard to play the ЕЕ-303"5 internal
synthesizer effect. To do this, vou will need to select one of
the synth-type algorithms (synth+delay, synth bass, synth
rhythm). Set the transmit channel of the external MIDI
keyboard to match the MIDI channel of the EF-303. For
example if the MIDI channel of the EF-303 is set to "1," set
the transmit channel of the external MIDI keyboard to "1."
