Python Midi package 0.1

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(M idiOutStream):

"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.m id'
midi_in = MidiInFile(even t_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.m id'
midi = MidiOutFile(out _file)

# non optional midi framework
midi.header()
midi.start_of_t rack()

# musical events

midi.update_tim e(0)
midi.note_on(ch annel=0, note=0x40)

midi.update_tim e(192)
midi.note_off(c hannel=0, note=0x40)

# midi framework

midi.update_tim e(0)
midi.end_of_tra ck() # not optional!

midi.eof()
############### ############### ###########


It cannot read/write midi ports at this point. So no realtime stuff yet.
