MidiMessage

ActiveSensing = 254

MIDI message sent repeatedly while the MIDI device is idle, to tell the receiver that the connection is alive. Most MIDI devices do not send this message.

Aftertouch = 10

MIDI message sent to indicate a change in pressure while a note is being pressed down, also called aftertouch.

ChannelPressure = 13

MIDI message sent to indicate a change in pressure for the whole channel. Some MIDI devices may send this instead of MIDI_MESSAGE_AFTERTOUCH.

Continue = 251

MIDI message sent to resume from the point the current sequence or song was paused.

ControlChange = 11

MIDI message sent when a controller value changes. In a MIDI device, a controller is any input that doesn't play notes. These may include sliders for volume, balance, and panning, as well as switches and pedals. See the General MIDI specification for a small list.

None = 0

Does not correspond to any MIDI message. This is the default value of InputEventMidi.Message.

NoteOff = 8

MIDI message sent when a note is released. Note: Not all MIDI devices send this message; some may send MIDI_MESSAGE_NOTE_ON with InputEventMidi.Velocity set to 0.

NoteOn = 9

MIDI message sent when a note is pressed.

PitchBend = 14

MIDI message sent when the value of the pitch bender changes, usually a wheel on the MIDI device.

ProgramChange = 12

MIDI message sent when the MIDI device changes its current instrument (also called program or preset).

QuarterFrame = 241

MIDI message sent every quarter frame to keep connected MIDI devices synchronized. Related to MIDI_MESSAGE_TIMING_CLOCK. Note: Getting this message's data from InputEventMidi is not implemented.

SongPositionPointer = 242

MIDI message sent to jump onto a new position in the current sequence or song. Note: Getting this message's data from InputEventMidi is not implemented.

SongSelect = 243

MIDI message sent to select a sequence or song to play. Note: Getting this message's data from InputEventMidi is not implemented.

Start = 250

MIDI message sent to start the current sequence or song from the beginning.

Stop = 252

MIDI message sent to pause the current sequence or song.

SystemExclusive = 240

MIDI system exclusive (SysEx) message. This type of message is not standardized and it's highly dependent on the MIDI device sending it. Note: Getting this message's data from InputEventMidi is not implemented.

SystemReset = 255

MIDI message sent to reset a MIDI device to its default state, as if it was just turned on. It should not be sent when the MIDI device is being turned on.

TimingClock = 248

MIDI message sent 24 times after MIDI_MESSAGE_QUARTER_FRAME, to keep connected MIDI devices synchronized.

TuneRequest = 246

MIDI message sent to request a tuning calibration. Used on analog synthesizers. Most modern MIDI devices do not need this message.
