(3-3) REGISTERED PARAMETER NUMBER (3-3-1) PITCH BEND SENSITIVITY RPN MSB 00H RPN LSB 00H DATA ENTRY MSB mmH mmH = 00H - 18H (0 - 24 semitones) DATA ENTRY LSB --- don't care * Set to 2 semitones at power-on. (3-3-2) MASTER FINE TUNE RPN MSB 00H RPN LSB 01H DATA ENTRY MSB mmH DATA ENTRY LSB llH (mmH, llH)= (00H, 00H) - (40H, 00H) - (7FH, 7FH) (-8192*100/8192) - 0 - (+8192*100/8192) (3-3-3) MASTER COARSE TUNE RPN MSB 00H RPN LSB 02H DATA ENTRY MSB mmH DATA ENTRY LSB --- don't care mmH = 28H - 40H - 58H (-24 - 0 - +24 semitones) (3-3-4) RPN RESET RPN MSB 7FH RPN LSB 7FH DATA ENTRY MSB --- don't care DATA ENTRY LSB --- don't care The RPN number is set to unspecified status. The internal data is not affected. (3-4) SYSTEM REAL TIME MESSAGES (3-2-1) ACTIVE SENSING STATUS 11111110 (FEH) Transmitted once approximately every 175 milliseconds. Sensing is initiated the first time this code is received. If no status or data core is received for more than about 350 milliseconds, the MIDI receive buffer is cleared and all current notes and the sustain switch are forced off. Also, all control values are reset. 5 (3-5) SYSTEM EXCLUSIVE MESSAGE (3-5-1) GENERAL MIDI MODE ON Sets the Utility mode PGC MODE parameter to GM. The following controllers are reset to the values shown. PITCH BEND CHANGE MODULATION EXPRESSION SUSTAIN SWITCH RPN VOLUME 0 (Center) 0 (Off) 127 (Maximum) 0 (Off) Unspecified status - internal data not affected. 100 (3-5-2) GENERAL MIDI MODE OFF Sets the Utility mode PGC MODE parameter to NORMAL. The following controllers are reset to the values shown. PITCH BEND CHANGE MODULATION EXPRESSION SUSTAIN SWITCH RPN VOLUME 0 (Center) 0 (Off) 127 (Maximum) 0 (Off) Unspecified status - internal data not affected. 100 (4) KEYBOARD SWITCH, SEQUENCER, AND TONE GENERATOR CONFIGURATION.
