1. Receive Data

■ Channel Voice Messages

* Following Channel Voice Messages can be received in [SETUP] - [MIDI] - [BASIC] MIDI Channel. * Not received when [SETUP] - [MIDI] - [BASIC] MIDI Tx/Rx Sw is set to “OFF.”

● Note On

Status 2nd byte 3rd byte 9n H kk H vv H n = MIDI channel number: 0H - FH (ch.1 - ch.16) kk = note number: 00H - 7FH (0 - 127) vv = note on velocity: 01H - 7FH (1 - 127)

* Only the note numbers assigned by the kit are received. For details on note numbers, refer to the PAD MIDI page of “TD-17 Data List” (PDF).

● Polyphonic Key Pressure

Status 2nd byte 3rd byte An H kk H vv H n = MIDI channel number: 0H - FH (ch.1 - ch.16) kk = note number: 00H - 7FH (0 - 127) vv = value 00H - 7FH (0 - 127)

* Only the note numbers assigned by the kit are received. For details on note numbers, refer to the PAD MIDI page of “TD-17 Data List” (PDF). * If the value is greater than 1, the decay of the note sounded by the received note number will be shortened based on the value (Used in choking).

● Control Change

○ Foot Controller (Controller number 4)

Status 2nd byte 3rd byte Bn H 04H vv H n = MIDI channel number: 0H - FH (ch.1 - ch.16) vv = Control value: 00H - 7FH (0 - 127: open to closed)

* Changes the position of the hi-hat control pedal.

● Program Change

Status 2nd byte Cn H pp H n = MIDI channel number: 0H - FH (ch.1 - ch.16) pp = Program number: 00H - 7FH (prog.1 - prog.128)

* Not Received when [SETUP]–[MIDI]–[BASIC] program Change Rx is set to “OFF.” * The sound changes starting with a new note-on that follows program change reception. A voice that was already sounding before the program change was received is not affected.

■ Channel Mode Messages

* Following Channel Voice Messages can be received in [KIT]–[MIDI]–[BASIC] MIDI Channel. * Not received when [SETUP]–[MIDI]–[BASIC] Tx/Rx Sw is set to “OFF.”

● All Sounds Off (Controller number 120)

Status 2nd byte 3rd byte Bn H 78H 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* When this message is received, all currently-sounding notes on the corresponding channel will be silenced. However, the status of channel messages will not change.

● Reset All Controllers (Controller number 121)

Status 2nd byte 3rd byte Bn H 79H 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* When this message is received, the polyphonic key pressure of all pads and the foot controller are reset to 0.

● All Notes Off (Controller number 123)

Status 2nd byte 3rd byte Bn H 7BH 00H n = MIDI channel number: 0H - FH (ch.1 - ch.16)

* The same processing will be carried out as when All Sounds Off is received.
