Press the key MIDI OUT Terminal NOTE ON • Note number (tone) • Velocity (volume) Release the key MIDI OUT Terminal NOTE OFF • Note number (tone) • Velocity (00) ❚ NOTE ❚ The pitch of a note depends on the tone that is being used, as shown in the "Note Table" on page A-1. Whenever this keyboard receives a note number that is outside its range for that tone, the same tone in the nearest available octave is substituted. PROGRAM CHANGE This is the tone select message. PROGRAM CHANGE can contain tone data within the range of 0 to 127. A PROGRAM CHANGE message is sent out through the keyboard's MIDI OUT terminal whenever you manually change its tone number. Receipt of a PROGRAM CHANGE message from an external device changes the tone setting of this keyboard. PITCH BEND This message carries pitch bend information for sliding pitch upwards or downwards during keyboard play. Performing a pitch bend operation on this keyboard simultaneously changes the pitch of the built-in sound source and sends a PITCH BEND message out through the MIDI OUT terminal. CONTROL CHANGE This message adds effects such as vibrato and volume changes. 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 send or received using CONTROL CHANGE. Effect BANK SELECT*1 Modulation Volume Pan Expression Hold1 Sostenuto Soft Pedal Effect depth RPN*2 Data Entry Control Number 0/32 1 7 10 11 64 66 67 91 100 / 101 6 / 38 *1 The BANK SELECT setting of PROGRAM CHANGE can be used to access any of this keyboard's 232 tones when selecting tones on this keyboard from an external device. The 232 tones are divided between four banks, as described below. Bank 0: 128 General MIDI tones (PROGRAM CHANGE 0 to 127) Bank 1: 64 variation tones (PROGRAM CHANGE 0 to 63) Bank 2: 8 drum sets (PROGRAM CHANGE 0 to 7) Bank 3: 32 user tones (PROGRAM CHANGE 0 to 31) 733A-E-065A Immediately prior to sending the PROGRAM CHANGE message, send two successive CONTROL CHANGE messages containing the following data. CONTROL NUMBER=0 CONTROL VALUE= CONTROL NUMBER=32 CONTROL VALUE= 0 ❚ NOTE ❚ Data received by the sound source of this keyboard over MIDI Channel 10 is always treated as drum set data, and can be sounded using one of the eight drum set sounds only. Because of this, PROGRAM CHANGE 0 through 7 always corresponds to drum set tones, so BANK SELECT data is not necessary when PROGRAM CHANGE is received over channel 10. *2 "RPN" stands for "Registered Parameter Number", which is a special control change number used when combining multiple control changes. The parameter being controlled is selected using the control values of control numbers 100 and 101, and then settings are made using the control values of DATA ENTRY (control numbers 6 and 38). This keyboard supports pitch bend sense, coarse tune, and fine tune RPNs sent from other MIDI machines. ❚ NOTE ❚ Sustain (CONTROL NUMBER 64), sostenuto (CONTROL NUMBER 66), and soft (CONTROL NUMBER 67) effects applied using the foot pedal can also be sent and received. ALL SOUND OFF This message forces all sound being produced over the current channel to stop. ALL NOTES OFF This message causes all notes being produced over the current channel due to NOTE ON messages to stop. This message is valid only for MIDI data notes. RESET ALL CONTROLLERS This messages initializes pitch bend and all other control changes. SYSTEM EXCLUSIVE* This message is used to control system exclusives, which are fine adjustments that are unique to a particular MIDI device. Originally, system exclusives were unique to a particular model, but now there are also universal system exclusives that are applicable to machines that are different models and even produced by different manufacturers. The following are the system exclusive messages supported by this keyboard. GM SYSTEM ON ([F0] [7E] [7F] [09] [01] [F7]) GM SYSTEM ON is used by an external machine to turn on this keyboard's GM system. "GM" stands for "General MIDI". • GM SYSTEM ON takes more time to process than other messages, so it can take more than 100 msec until the next message is processed. GM SYSTEM OFF ([F0] [7E] [7F] [09] [02] [F7]) GM SYSTEM OFF is used by an external device to turn off this keyboard's GM system. EFFECT CHANGE ([F0] [44] [0B] [09] [XX] [F7]) EFFECT CHANGE switches between the keyboard's internal digital effects. The "XX" parameter in the syntax shown above stands for a hexadecimal value that represents an effect number sent from an external machine. A list of the hexadecimal values that can be specified and their meanings is shown below. E-63 WK-1800/1600(E)-60~66 Page 63 03.7.31, 5:22 PM Adobe PageMaker 6.5J/PPC
