Yamaha 1100 Manual Do Utilizador

MIDI performance data is assigned to one of sixteen 
MIDI channels. Using these channels, 1 - 16, the 
performance data for sixteen different instrument parts 
can be simultaneously sent over one MIDI cable.

Think of the MIDI channels as TV channels. Each TV 
station transmits its broadcasts over a specific 
channel.Your home TV set receives many different 
programs simultaneously from several TV stations and 
you select the appropriate channel to watch the desired 
program.

MIDI operates on the same basic principle. The 
transmitting instrument sends MIDI data on a specific 
MIDI channel (MIDI Transmit Channel) via a single 
MIDI cable to the receiving instrument. If the receiving 
instrument’s MIDI channel (MIDI Receive Channel) 
matches the Transmit Channel, the receiving instrument 
will sound according to the data sent by the 
transmitting instrument.

For example, several tracks (channels) can be 
transmitted simultaneously, including the style data (as 
shown below). 

Example: Recording the auto accompaniment of the PSR-2100/
1100 to an external sequencer

As you can see, it is essential to determine which data 
is to be sent over which MIDI channel when 
transmitting MIDI data (page 149). The PSR-2100/1100 
also allows you to determine how the received data is 
played back. (page 150).

■ System Messages

This is data that is used in common by the entire MIDI 
system. System messages include messages like Exclusive 
Messages that transmit data unique to each instrument 
manufacturer and Realtime Messages that control the 
MIDI device.

The messages transmitted/received by the PSR-2100/1100 
are shown in the MIDI Data Format and MIDI 
Implementation Chart in the separate Data List.

The following MIDI settings can be made on the PSR-
2100/1100:
• MIDI templates (preset MIDI setups for various 

• Transmit (page 149)
• Receive (page 150)
• Local Control (page 148)
• Clock (page 149)

■

Record performance data (1-16 channels) using the 
PSR-2100/1100 Auto Accompaniment features on a 
external sequencer (such as a personal computer). 
After recording, edit the data with the sequencer, then 
play it again on the PSR-2100/1100 (playback). 

When you want to use the PSR-2100/1100 as an XG-
compatible multi-timbral tone generator, set the receive 
part for MIDI channels 1 to 16 to “SONG” in MIDI 
Receive (page 150).

Play and control the PSR-2100/1100 from a separate 
keyboard

The PSR-2100/1100’s keyboard and internal tone generator are 
also connected by MIDI (page 148).
