* When “GENERAL3 (18)” is assigned to either [SYSTEM]-[MIDI]-[CONTROL] Snare CC (for head and rim of SNARE pad), Ride CC (for bow of
RIDE pad), or Toms/AUXs CC (for head and rim of TOM 1–3, AUX 1–3 pads).
* When the [SYSTEM]-[TRIGGER]-[PARAM] Trig Type is set to a type that can detect the strike position, or a digitally-connected pad that
can detect strike position is assigned.
* When Head and Rim for Position Detect for [SYSTEM]-[TRIGGER]-[PARAM] are set to “ON.”
○General Purpose Controller 4 (Controller number 19)
Status 2nd byte 3rd byte
BnH 13H vvH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
vv = Control value: 00H–7FH (0–127)
Pedal position: open to closed
Head strike position: center to perimeter
Rim strike position: deep to shallow
* In the channel to which the HI-HAT<BOW> is assigned, when [SYSTEM]-[MIDI]-[CONTROL] HH Pedal CC is set to “GENERAL4 (19),” this is
transmitted when the hi-hat control pedal is played. When the HI-HAT pad is struck, this is transmitted as a pedal position message before
Note On.
* When the following three things are set, strike position data will be transmitted before the note-on data when a pad is struck.
* When “GENERAL4 (19)” is assigned to either [SYSTEM]-[MIDI]-[CONTROL] Snare CC (for head and rim of SNARE pad), Ride CC (for bow of
RIDE pad), or Toms/AUXs CC (for head and rim of TOM 1–3, AUX 1–3 pads).
* When the [SYSTEM]-[TRIGGER]-[PARAM] Trig Type is set to a type that can detect the strike position, or a digitally-connected pad that
can detect strike position is assigned.
* When Head and Rim for Position Detect for [SYSTEM]-[TRIGGER]-[PARAM] are set to “ON.”
○High Resolution Velocity Prefix (Controller number 88)
Status 2nd byte 3rd byte
BnH 58H kkH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
kk = High resolution velocity prefix: 00H–40H (0–64)
* Not transmitted when [SYSTEM]-[MIDI]-[CONTROL] HI-Reso Velocity is set to “OFF.”
* When you strike a digitally-connected pad, the strike strength (velocity) is expressed in 0.5 steps across 317 levels (1, 1.5, …
,158.5, 159), and is transmitted before the note-on as follows according to the velocity.
* When the velocity is less than 127 and the decimal portion is 0
The high resolution velocity prefix is 0.
* When the velocity is less than 127 and the decimal portion is 0.5
The high resolution velocity prefix is 64.
* When the velocity is 127 or more
If we let the high resolution velocity be “x,” high resolution velocity prefix is (x-127)/0.5.
* Velocity values below the decimal point are not expressed in the screen of the TD-27. If we let the velocity be “x,” velocities above
127 are expressed as “127+(x-127).”
●Program Change
Status 2nd byte
CnH ppH
n = MIDI channel number: 0H–FH (ch.1–ch.16)
pp = Program number: 00H–63H (prog.1–prog.100)
* Not transmitted when [SYSTEM]-[MIDI]-[BASIC] Program Change TX is set to “OFF.”
■System Realtime Messages
●Timing Clock
Status
F8H
* Not transmitted when [SYSTEM]-[MIDI]-[SYNC] Sync Out is set to “OFF.”
●Active Sensing
