The LED lights when the MIDI channel is on. The LED goes out when the MIDI channel is off. Active sensing This message checks if the MIDI cable is disconnected. Once GZ-500 has received this message, it always counts time of an interval to a next MIDI message. In case when GZ-5 receives no MIDI message for 420 msec of time, it will stop sound output and reset all controllers, then it will cancel the function of active sensing. —6— Transmittable Messages Note No.: Velocity: Note Off: Program Change: Pitch Bend: Control Change: Exclusive: 12 ~ 72 (Oct. shift -2), 24 ~ 84 (Oct. shift -1) 36 ~ 96 (Oct. shift 0), 48 ~ 108 (Oct. shift 1) 1 ~ 127 velocity 0 0 ~ 127 (Channels 1 - 9 & 11 - 16), 0 ~ 7 (Channel 10) 00H / 00H ~ 7FH / 7FH Modulation 0 ~ 127 Volume 0 ~ 127 Pan 0 ~ 127 Expression 0 ~ 127 Sustain 0: Off, 127: On Sosutenuto 0: Off, 127: On Soft 0: Off, 127: On Effect Depth 0 ~ 127 Pitch Bend Sense 00H / --H ~ 0CH / --H (12 seminotes) Coarse Tune 34H / --H ~ 40H / --H ~ 4CH / --H (-12 seminotes) ~ (center) ~ (+12 seminotes) Fine Tune 20H / 00H ~ 40H / 00H ~ 60H / 00H (-50 cents) ~ (center) ~ (+50 cents) All Notes Off All Sounds Off Reset All Controllers Effect Change General MIDI On Receivable Messages Note No.: Velocity: Note Off: Program Change: Pitch Bend: Control Change: Channel Pressure: Exclusive: 0 ~ 127 1 ~ 127 velocity 0 0 ~ 127(Channels 1 - 9 & 11 - 16), 0 ~ 7 (Channel 10) 00H / 00H ~ 7FH / 7FH Modulation 0 (0 cent) ~ 127 (+/-50 cents) Volume 0 ~ 127 Pan 0 (Left) ~ 64 (Center) ~ 127 (Right) Expression 0 ~ 127 Sustain 0 ~ 63: Off, 64 ~ 127: On Sosutenuto 0 ~ 63: Off, 64 ~ 127: On Soft 0 ~ 63: Off, 64 ~ 127: On Effect Depth 0 ~ 127 Pitch Bend Sense 00H / --H ~ 0CH / --H (12 seminotes) Coarse Tune 34H / 00H ~ 40H / 00H ~ 4CH / 00H (-12 seminotes) ~ (center) ~ (+12 seminotes) Fine Tune 20H / 00H ~ 40H / 00H ~ 60H / 00H (-50 cents) ~ (Center) ~ (+50 cents) RPN Null All Notes Off All Sounds Off Reset All Controllers 0 (0 cent) ~ 127 (+/-50 cents) Effect Change General MIDI On Active Sensing —7— BLOCK DIAGRAM LED driver Q104 ~ Q111 MIDI OUT IN La ~ Lg, Lp LS0 ~ LS7 KO1 ~ KO3 P41 P40 KO Signal KO0 ~ Generator IC102 KO5 TC74HC174AF CPU LSI106 HD6433298A42F Keyboard LED driver IC371 BA612 7-seg.

The CPU then initializes its internal circuit and clears the working storage RAM. When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU provides APO signal to the power supply circuit and raises RESET signal to +5V to reset the DSP, the key controller and the KO signal generator.

Then it provides 16-bit serial signal containing data of the melody, chord, bass, and percussion to the DAC. When an effect selected, the DSP adds the effect to the sound data using a 256k-bit RAM.
