If anybody is interrested in Midi, but are not on the Python Midi list,
I will just notify that I have released the first version of a high
level midi package for Python.
It is fully functional. It reads and writes midi files! It is *very*
easy to write your own event handlers to make midi files do whatever you
want them to.
It uses the same general ideas as the Sax parser for xml.
#########################################
# example #1
"""
This prints all note_on events on midi channel 0. It's a short example
of creating your own event handler by subclassing the MidiOutStream.
"""
from MidiOutStream import MidiOutStream
from MidiInFile import MidiInFile
class NoteOnPrinter(MidiOutStream):
"Prints all note_on events on channel 0"
def note_on(self, channel=0, note=0x40, velocity=0x40):
if channel == 0:
print channel, note, velocity, self.rel_time()
event_handler = NoteOnPrinter()
in_file = 'midiout/minimal_type0.mid'
midi_in = MidiInFile(event_handler, in_file)
midi_in.read()
#########################################
#########################################
# example #2
"""
This is an example of how to create the smallest possible type 0 midi
file, where all the midi events are in the same track.
"""
from MidiOutFile import MidiOutFile
out_file = 'midiout/minimal_type0.mid'
midi = MidiOutFile(out_file)
# non optional midi framework
midi.header()
midi.start_of_track()
# musical events
midi.update_time(0)
midi.note_on(channel=0, note=0x40)
midi.update_time(192)
midi.note_off(channel=0, note=0x40)
# midi framework
midi.update_time(0)
midi.end_of_track() # not optional!
midi.eof()
#########################################
It cannot read/write midi ports at this point. So no realtime stuff yet.
