Description
Provides a simple interface for MIDI I/O.
To add Midi support to your application you call:
require "luamidi"
See luamidi syntax for full syntax.
Examples
Example for getting a message
local midiCount=luamidi.getinportcount()
if midiCount==0 then return end -- no midi device
_midiDeviceName=luamidi.enumerateinports()[0] -- the name of the device at first IN port
local s, n, v, _t = pcall(luamidi.getMessage, 0) -- get message at first IN port
if not status then return end
Example for sending a message
local midiCount=luamidi.getoutportcount()
if midiCount==0 then return end -- no midi device
_midiDeviceName=luamidi.enumerateoutports()[0] -- the name of the device at first OUT port
luamidi.sendMessage(0, 144, 60, 127) -- send a maximum velocity (volume/strength) Note On middle C message to first OUT port
luamidi.sendMessage(0, 144, 60, 0) -- send a Note Off middle C message to first OUT port
Methodsluamidi:base0 sets that when sending messages the channels are in the range 0-15 |
