* The amount of data that can be transmitted at once time will depend on the type
of data, and data must be requested using a specific starting address and size.
* If "Data Set 1" is transmitted successively, there must be an interval of at least
40 ms.
* Regarding the checksum please refer to Page 123.
2. Transmit data
* In wave mode, the SPD-S sends no messages other than active sensing.
* Messages included in Phrase Maker data are not transmitted.
Status
* When SETUP/MIDI/Soft Thru is set to "ON", messages received in addition to
F7H
the following messages are also sent.
Channel Voice Messages
* The following channel voice messages are transmitted on the channel specified
in the SETUP/MIDI/MIDI Channel.
Note Off
Status
8nH
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 message is sent when the time specified in PATCH/PAD
CONTROL/Gate Time has lapsed after a pad has been struck.
Note On
Status
9nH
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)
Control Change
* Not transmitted when SETUP/MIDI/CC TX/RX Switch is set to "OFF." (Initial
Value is ON)
Foot Control (Controller number 4)
Status
BnH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
vv = Control value: 00H - 7FH (0 - 127) 0-63=OFF, 64-127=ON
* This message is sent when the foot switch to which WAVE SW is assigned in
SETUP/CONTROL SW is depressed. The transmission is not triggered if any
other function is assigned to the foot switch.
Expression (Controller number 11)
Status
BnH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
vv = Control value: 00H - 7FH (0 - 127)
* The SPD-S tramsmits a value corresponding to the position of the Expression
pedal.
Effect Control 1 (Controller number 12)
Status
BnH
n = MIDI channel number: 0H - FH (ch.1 - ch.16)
vv = Control value: 00H - 7FH (0 - 127)
