RHYTHM TEMPO NOTE ON/OFF This message sends data when a key is pressed (NOTE ON) or released (NOTE OFF). A NOTE ON/OFF message includes a note number (to indicate note whose key is being pressed or released) and velocity (velocity=100 when the volume value of this unit is 9 to 2, and velocity=75 when the volume value is 1 or 0). NOTE ON velocity is always used to determine the relative volume of the note. This keyboard does not receive NOTE OFF velocity data. Whenever you press or release a key on this keyboard, the corresponding NOTE ON or NOTE OFF message is sent by constant velocity from the MIDI OUT terminal. PROGRAM CHANGE This is the tone selection message. PROGRAM CHANGE can contain tone data within the range of 0 to 127. A PROGRAM CHANGE message (0 to 99) is sent out through this keyboard's MIDI OUT terminal whenever you manually change its tone number. Receipt of a PROGRAM CHANGE message from an external machine changes the tone setting of this keyboard. This keyboard can send tone data within the range of 00 to 99 and receive tone data within the range of 0 to 127*. Each of the 128 General MIDI tones is automatically assigned to one of the keyboard's 100 built-in tones as shown on page A1. Select this setting when you want to listen to General MIDI data from a computer or other external equipment. * When GM mapping is turned on (page E-31). When turned off, tone data is received in the range of 0 to 99. ❚ NOTE • Channel 10 is for the drum part only, and it does not receive Program Change messages. When receiving MIDI data, it sounds percussion sounds produced by this keyboard. PITCH BEND This message carries pitch bend information for smoothly sliding the pitch upwards or downwards during keyboard play. This keyboard does not send pitch bend data, but it can receive such data. SONG BANK CONTROL CHANGE This message adds effects such as vibrato and volume changes applied during keyboard play. CONTROL CHANGE data includes a control number (to identify the effect type) and a control value (to specify the on/off status and depth of the effect). The following is a list of data that can be received using CONTROL CHANGE. Effect VOLUME HOLD1 MODULATION Control Number 7 64 1 LOCAL CONTROL (Default: on) /GM mapping (Default: off) This setting determines whether or not the keyboard and sound source of this keyboard are connected internally. When recording to a computer or other external device connected to this keyboard's MIDI IN/OUT terminal, it helps if you turn LOCAL CONTROL off. on: Anything played on the keyboard is sounded by the internal sound source and simultaneously output as a MIDI message from the MIDI OUT terminal. oFF: Anything played on the keyboard is output as a MIDI message from the MIDI OUT terminal, without being sounded by the internal sound source. Turn LOCAL CONTROL off whenever you are using the MIDI THRU function of a computer or other external device. Also note that no sound is produced by the keyboard if LOCAL CONTROL is turned off and no external device is connected. ❚ NOTE • When you are using this keyboard in a stand-alone configuration, keyboard keys do not light while local control is turned off.
