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

Methods

luamidi:base0 sets that when sending messages the channels are in the range 0-15
luamidi:base1 sets that when sending messages the channels are in the range 1-16
luamidi:enumerateinports gets a table of Midi IN port names
luamidi:enumerateoutports gets a table of Midi OUT port names
luamidi:getInPortName gets the Midi IN port name
luamidi:getMessage gets the next incoming message from the queue of the chosen IN port
luamidi:getOutPortName gets the Midi OUT port name
luamidi:getinportcount gets the number of Midi IN ports
luamidi:getoutportcount gets the number of Midi OUT ports
luamidi:noteOff sends a Note Off message to the chosen OUT port
luamidi:noteOn sends a Note On message to the chosen OUT port
luamidi:openin opens the Midi IN port
luamidi:openout opens the Midi OUT port
luamidi:sendMessage sends a message to the chosen OUT port
luamidi:setQueueSizeLimit sets the Midi queue size limit

Events

Constants
