MidiGetEventFiltered(boolean allowNoteOn, boolean allowNoteOff, boolean allowCC, boolean allowProgramChange, boolean allowAftertouch, boolean allowPitchBend, boolean allowOthers, int delay, table allowedSources)

Apply a filter to Midi.GetEvent to exclude some Midi messages and return all events since last call.

You can exclude:

1. message you don't need, e.g. aftertouch
2. a lot of steps while moving a controller (slider, knob, pitch bend).
   To do this, set a delay in milliseconds. This result in a loss of data, note suitable for fine control of sound, but useful when hardware controllers replace mouse or computer keyboard inputs.

Return

table: Table of Midi events, each item are structured as:

• Event, int: type of event :
  • 1 mean note on (key pressed),
  • 2 mean note off or note on with velocity = 0 (key released)
  • 10 means polyphonic aftertouch
  • 11 means CC, Controller Change (modulation wheel, pedal, knobs, cursors, bank change...)
  • 12 means PC, Program Change
  • 13 means channel aftertouch
  • 14 means pitch bend
• Channel, int: the channel from 0 to 15
• Pitch, int: the note pitch / selected controller / program from 0 to 127
• Velocity, int: the velocity / controller value from 0 to 127
• TimeMs, int: the time position in millisecond of the event
• TimePos, number: the time position in the playing score (-1 if no score currently playing)
• Source, int: the source for this event (MSDefine constant):
  • INPUT_SOURCE_UNKNOWN: none/unknown
  • INPUT_SOURCE_MIDI: from an external MIDI device
  • INPUT_SOURCE_VIRTUAL_KBD: from a click on a virtual keyboard
  • INPUT_SOURCE_COMPUTER_KBD: from the computer keyboard
  • INPUT_SOURCE_PLAYED_MUSIC: from the played score

MidiSendCC(int interface, int channel, int controller, int value)

Send a control change (CC) message to a MIDI device.
