Using Your PSR-2100/1100 with Other Devices MIDI channels 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. Weather Report News 1 2 2 News 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. MIDI transmit channel 2 MIDI cable MIDI receive channel 2 The PSR-2100/1100's keyboard and internal tone generator are also connected by MIDI (page 148). 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 PSR-2100/1100 track (channnel) MAIN LAYER LEFT STYLE instrument STYLE instrument STYLE instrument STYLE instrument STYLE instrument STYLE instrument STYLE instrument STYLE instrument MIDI cable or serial cable Channel 1 Channel 2 Channel 3 Channel 4 Channel 5 Channel 6 Channel 7 Channel 8 Channel 9 Channel 10 Channel 11 External sequencer Track 1 Track 2 Track 3 Track 4 Track 5 Track 6 Track 7 Track 8 Track 9 Track 10 Track 11 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. Message Name System Exclusive Message Realtime Messages PSR-2100/1100 Operation/Panel Setting Effect type settings (Mixing Console), etc. Clock setting, Start/stop operation 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.
