Greetings,
Another module: http://www.pjb.com.au/comp/lua/MIDI.lua
doc homepage: http://www.pjb.com.au/comp/lua/MIDI.html
test script: http://www.pjb.com.au/comp/lua/test_mi.lua
version: 3.7
MIDI.lua - for Reading, writing and manipulating MIDI data
translates the MIDI data into Lua variables and back, e.g.
local MIDI = require 'MIDI'
local my_score = {
96, -- ticks per beat
{ -- first track
{'patch_change', 0, 1, 11}, -- vibraphone on channel 1
{'set_tempo', 0, 750000}, -- microseconds per beat
{'note', 5, 96, 1, 25, 100},
{'note', 101, 96, 1, 29, 100},
}, -- end of first track
}
local f = assert(io.open('f.mid','wb'))
f:write(MIDI.score2midi(my_score))
f:close()
and, aside from offering this low-level access, also offers a
number of different functions to perform common manipulations.
It's a translation into Lua of my Python module:
http://www.pjb.com.au/midi/MIDI.html
http://www.pjb.com.au/midi/free/MIDI.py
which is the basis of my midisox program, which already has a
Perl version, and may soon get a Lua version...
( Translating is a process which I find really instructive; plus
I really like having compatible calling-interfaces to my most-
-needed-stuff in different languages; also the resulting study
of the code and the new test-scripts finds and fixes lots of
little bugs that no-one seems to spot otherwise. )
May it be useful, let me know of problems,
Peter Billam
