When the MIDI IN connector receives active sensing messages, it will enter the Active sensing message (or other MIDI messages) are not received at 420millisecond intervals, the device will judge that cable is disconnected or there is damages connection. All sounds will be cut off, and a reset all controllers message will be processed. Monitoring for active sensing messages is terminated. 4-7, System Exclusive messages Exclusive messages are used to control a characteristic operation of the device. Universal system exclusive messages can be used for all devices- regardless of the manufacturer. General Exclusive message, however cannot convey data between different models. * GM system on (Universal Non-Real time System Exclusive) When the GM ‘system on’ message is received, the General MIDI basic setting will be set, reception of NRPN will not be possible if a GM ‘system on’ is received. The GS reset MIDI message is included at the beginning of song data that carries the GM mark. When the song data played from the beginning, the device will be automatically initialized to the basic settings. * GS reset (GS format common Syste m Exclusive) When the GS reset message is received, the GS basic settings will be set. When GS reset is recevied, the NRPNS specified with the GS format can be received. The GS reset MIDI message is included at the beginning of song data that carries the GS mark. When the song data is played from the beginning, the device will be automatically initialized to the basic settings. * Master volume (Universal Real Time System Exclusve) This is common universal Exclusive message for controlling the mater volume of all parts. a gg? oo Tem

Therefore the PCM memory can be used for 64BANKs of 512 tables of 256 samples. But a single PCM sample cannot cross a BANK boundary. The GM82C650 sample Control parameter is implemented at the “Table” Level. In another words, The “Table” is a collection of 256 consecutive PCM samples starting at an address multiple of 256. So, the PCM samples stored in memory must be sampled by the multiple of 256. <WORD 0> | cs/] wei] RD/[Ai[AoT 7 [| be | 0s | b4 | Ds [| b2 | bt | 00 | Polo t fool sutadess [0 | o | o] 0 fof of 4 fos | tr [cre [irs [irs [ers [cre [its | 170 | pepe tsp ee pet ete peta <WORD 1> [esi[ Wa] ROAT[AO] O7 | D6 [Ds] Da] S| ba] DI] DOT Pofoltfolo| Swtadress | 0 | 0} o] 1] | of of} + [ols [ctr {ere crs | cra [crs | cr2 [cri | cro | fof of 4] 1]o | ere {ers | era | ers [ert | ert | eto | cre | pofotstififusTo [a [a fs [st [ere fer | * LT [8:0] : Loop table address. * BK [5:0] : BANK address. * CT [8:0] : Current table address. * ET [8:0] : END table address. «2 S46028757 0006052 530 aT

The PI value of “00800(hex)” will replay the original sampling frequency. ( address increase of 1/frame ) For example, if the sample was originally sampled at the frame rate, then amount at trans- position is given by PI/2048. (A PI value of 00800(hex) will transpose the signal down one octive and a PI value of 01000(hex) will transpose the signal up one octive.)

@ LG Semicon. Co., LTD. 4-1. Control Change These message control the modulation and pan, etc. Each function is classfied with a Control Change number. * Modulation (control change number 1) A vibrato effect is applied when this message is received. ¢ Volume (control change number 7) This message conveys the volume level of the part. The part’s volume will change when this message is received + Expression (control change number 11) This message conveys the change in volume. This is used to lower or raise the volume during a song. * The part volume will change with either the volume message (control change 7) or expression message (control change] 1). Note that if a 0 value is receivedwith either of the message, the part volume will be 0,and the part’s volume will not increase even with the other message. + Pan (control change number 10) This message conveys the part’s pan (effect position during streo output) * Hold(1) (control change number 64) This message conveys the prressing and releasing of the damper (sustain) pepal. Notes will be held when ‘hold on’ is received. Sounds which decay naturally (such as pianos) will decay more slowly when a ‘hold on’ is received. Sustaining sounds (such as organs) will be held until ‘hold off’ is received. + Sostenuto (control change number 66) The pedal that sustains notes only when the pedal is pressed down is called the sostenuto pedal. This message conveys the action of pressing and releasing this pedal. When ‘sostenuto on’ is received, only notes played at the same time will be sustained. Sounds which decy naturally(such as painos) will decay more slowly when a ‘sostenuto on’ is received. Sustaining sounds (such as organs) will be held until ‘hold off” is recevied. * Soft (control change number 67) The pedal that softens the sound of notes played is called the soft pedal. This message conveys the action of pressing and releasing this pedal. When ‘soft on’ is received, the cut off frequency is lowered, and a soft sound is achieved.

@ LG Semicon. Co., LTD. 4-2. Aftertouch (Channel pressure ) Afiertouch refers to pressing down on a key after playing a note. The variation in aftertouch pressure can create changes in the sound produced. There pressure affects all note numbers in the same MIDI channel. Polyphonic key pressure affects only the key (note number) that is pressed with the greatest force. 4- 3. All sounds off This messgae tums off all sounds which are currently playing, The sounds in the corresponding channel will be turned off. 4-4. All notes off This message tums all ‘note on’ message to ‘note off’ messages. However, if hold 1 or sostenuto is tumed on, the sound will not stop until these turn off. 4-5.

All sounds will be cut off, and a reset all controllers message will be processed. Monitoring for active sensing messages is terminated. 4-7, System Exclusive messages Exclusive messages are used to control a characteristic operation of the device. Universal system exclusive messages can be used for all devices- regardless of the manufacturer. General Exclusive message,however cannot convey data between different models. *GM system on (Universal Non-Real time System Exclusive) When the GM ‘system on’ message is received, the General MIDI basic setting will be set, reception of NRPN will not be possible if a GM ‘system on’ is received. The GS reset MIDI message is included at the beginning of song data that carries the GM mark. When the song data played from the beginning, the device will be automatically initialized to the basic settings. * GS reset (GS format common Syste m Exclusive) When the GS reset message is received, the GS basic settings will be set. When GS reset is recevied, the NRPNS specified with the GS format can be received. The GS reset MIDI message is included at the beginning of song data that carries the GS mark.
