Connecting other MIDI devices
When the SGproX is used as a MIDI master keyboard, it can control one channel
of external MIDI devices in Program mode, or eight channels of external MIDI
devices in Performance mode.
This section provides a simple explanation of how an external MIDI device can be
controlled by the SGproX in Program mode.
For details on the control functions, refer to Controllers / MIDI ( p.55).
What is MIDI?
MIDI (Musical Instrument Digital Interface) is a standard specification that allows musical performance
data from an instrument (notes played on a keyboard, sound selections etc.) to be exchanged as digital data
between electronic musical instruments and computers etc.
This allows you to control other MIDI instruments by playing the SGproX. When you select sounds or
operate the damper pedal etc., all of this information is transmitted as well.
In a similar way, musical data can be transmitted from another MIDI keyboard or sequencer (automatic
playback device) to control the SGproX.
The following section will explain ways in which the SGproX can use MIDI. If you wish to learn more about
MIDI, you can refer to the numerous books on MIDI that have been published.
Connecting MIDI cables
You will need to provide an additional MIDI device, and have its owner’s manual at hand for reference.
• Connect a MIDI cable to the SGproX’s MIDI OUT A, and the other end of the cable to the MIDI IN of
the MIDI device that you wish to control. (The SGproX will be the transmitting device.) *MIDI OUT B
is not used in Program mode.
• If you wish to control the SGproX from the other MIDI device, use a MIDI cable to connect the SGproX’s
MIDI IN to the other MIDI device’s MIDI OUT. (The SGproX will be the receiving device.)
If you wish only to control the other MIDI device from the SGproX, or only to control the SGproX from the
other device, use only one cable.
Setting the MIDI channels
1. Press the
〈
GLOBAL
〉
switch (The LED will blink) and you will enter Global mode.
2. In the
〈
CHANNEL
〉
page (select switch 1), select the same channel as the MIDI device that is connected.
MIDI messages will be transmitted and received on this channel.
3. Press the
〈
GLOBAL
〉
switch (The LED will turn off) and you will return to PROGRAM mode.
If the other MIDI device is a tone generator or keyboard (that can produce sound), it will play when you play
the SGproX’s keyboard. (If the MIDI OUT A of the SGproX is connected to the MIDI IN of the other MIDI
device)
If the external MIDI device connected to the SGproX’s MIDI IN is a sequencer or keyboard (that can
transmit performance data), the SGproX will sound in accordance with the incoming data from the external
device.
