Member Function Documentation

corresponds()

bool corresponds

(

const MidiEvent &

b

)

const

this method checks if the messages described with b correspond to this message (using the OMNI wildcards)

getData()

std::vector<unsigned char> getData

(

)

const

Returns a raw data midi message that corresponds to the event and can be sent through midi output port.

getPitchBendValue()

float getPitchBendValue

(

)

const

If a pitch bend event, this returns the pitchbend amount between -1 and 1.
