Module
MEI.midi
Attributes
midi.instrname, midi.instrnum, midi.pan, midi.patchname, midi.patchnum, midi.volume
midi.instrname(optional)Provides a General MIDI label for the MIDI instrument. Value conforms to data.MIDINAMES.
midi.instrnum(optional)Captures the General MIDI instrument number. Use an integer for a 0-based value. An integer preceded by "in" indicates a 1-based value. Value conforms to data.MIDIVALUE.
midi.pan(optional)Sets the instrument's position in a stereo field. MIDI values of 0 and 1 both pan left, 127 or 128 pans right, and 63 or 64 pans to the center. Positve percentage values pan to the right, negative ones to the left. 0% is centered. Value conforms to data.MIDIVALUE_PAN.
midi.patchname(optional)Records a non-General MIDI patch/instrument name. Value is a NMTOKEN.
midi.patchnum(optional)Records a non-General MIDI patch/instrument number. Value conforms to data.MIDIVALUE.
midi.volume(optional)Sets the instrument's volume. Value conforms to data.MIDIVALUE_PERCENT.
midi.instrnum(optional)Captures the General MIDI instrument number. Use an integer for a 0-based value. An integer preceded by "in" indicates a 1-based value. Value conforms to data.MIDIVALUE.
midi.instrname(optional)Provides a General MIDI label for the MIDI instrument. Value conforms to data.MIDINAMES.
midi.pan(optional)Sets the instrument's position in a stereo field. MIDI values of 0 and 1 both pan left, 127 or 128 pans right, and 63 or 64 pans to the center. Positve percentage values pan to the right, negative ones to the left. 0% is centered. Value conforms to data.MIDIVALUE_PAN.
midi.patchname(optional)Records a non-General MIDI patch/instrument name. Value is a NMTOKEN.
midi.patchnum(optional)Records a non-General MIDI patch/instrument number. Value conforms to data.MIDIVALUE.
midi.volume(optional)Sets the instrument's volume. Value conforms to data.MIDIVALUE_PERCENT.
