Panel operations on the PSR-2000/1000, such as playing the keyboard and selecting voices, are processed and stored as MIDI data. The auto accompaniment styles and songs also consist of MIDI data.

MIDI is an acronym that stands for Musical Instrument Digital Interface, which allows electronic musical instruments to communicate with each other, by sending and receiving compatible Note, Control Change, Program Change and various other types of MIDI data, or messages.

The PSR-2000/1000 can control a MIDI device by transmitting note related data and various types of controller data.The PSR-2000/1000 can be controlled by incoming MIDI messages which automatically determine the tone generator mode, select MIDI channels, voices and effects, change parameter values and of course play the voices specified for the various parts.

MIDI data has the following advantages over audio data:

•The amount of data is much less, letting you easily store MIDI songs to floppy disk.

•The data can be effectively and easily edited, even to the point of changing voices and transforming the data.

MIDI messages can be divided into two groups: Channel messages and System messages.

■Channel Messages

The PSR-2000/1000 is an electronic instrument that can handle 16 channels (or 32 channels, when using the TO HOST terminal). This is usually expressed as “it can play 16 instruments at the same time.” Channel messages transmit information such as Note ON/OFF, Program Change, for each of the 16 channels.

Message Name

PSR-2000/1000 Operation/Panel Setting

 

 

 

 

Note ON/OFF

Messages which are generated when the

 

 

 

keyboard is played. Each message includes

 

 

 

a specific note number which corresponds

 

 

 

to the key which is pressed, plus a velocity

 

 

 

value based on how hard the key is played.

 

 

 

 

Program Change

Voice selecting (control change bank select

 

 

 

MSB/LSB setting)

 

 

 

 

Control Change

Volume, panpot (Mixing Console), etc.

 

 

 

 

 

 

 

 

 

 

 

 

The performance data of all songs and styles is handled as MIDI data.

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.

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.

The PSR-2000/1000’s keyboard and internal tone generator are also connected by MIDI (page 145).

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