The size of data that can be transmitted at one time is fixed for each type of data.
And data requests must be made with a fixed starting address and size. Refer to the address and size given in “3. Parameter Address
Map”(p. 5).
* For the checksum, refer to p. 34.

* The amount of data that can be transmitted at one time depends on the type of data, and data will be transmitted from the specified
starting address and size. Refer to the address and size given in “3. Parameter Address Map” (p. 5).
* Data larger than 256 bytes will be divided into packets of 256 bytes or less, and each packet will be sent at an interval of about
20 ms.
* Regarding the checksum, please refer to p. 34.
2. Transmit Data
* If the [SETUP]-[MIDI]-[THRU] Bluetooth setting (except for the TD-17-L) or USB setting is "ON," received messages are also
transmitted to the corresponding jack as well as the messages listed below.
■ Channel Voice Messages
* The following channel voice messages are transmitted on the channel specified as the [SETUP]-[MIDI]-[BASIC] MIDI Channel.
* Not transmitted when [SETUP]-[MIDI]-[BASIC] MIDI Tx/Rx Sw is set to “OFF.”
● Note Off
Status 2nd byte 3rd byte
8nH kkH vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = note number: 00H–7FH (0–127)
vv = Note off velocity: 40H (64) fixed
* A note-off is transmitted 0.1 seconds after you strike a pad or use the hi-hat control pedal to play a foot close (splash).
● Note On
Status 2nd byte 3rd byte
9nH kkH vvH
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)
* The note number assigned by the kit is transmitted when you strike a pad or use the hi-hat control pedal to play a foot-close
(splash).
* If the [KIT]-[XSTICK] Xstick Switch is "ON," and you play the SNARE pad using the cross-stick technique, the note number assigned
by [OTHER]-[MIDI NOTE] SNARE <XSTICK> is transmitted.
* The note number that is transmitted when you strike the hi-hat pad (open or closed) is switched depending on how deeply the hi-hat
pedal is being pressed.
● Polyphonic Key Pressure
Status 2nd byte 3rd byte
AnH kkH vvH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
kk = note number: 00H - 7FH (0 - 127)
vv = value 00H, 7FH (0, 127)
* This message is transmitted on the note number assigned to the head and the rim, with a value of 7FH when the rim of the pad is
pressed or with a value of 00H when the rim is released.
