Description

Provides a simple interface for MIDI I/O.

To add Midi support to your application you call: <syntaxhighlight lang="lua"> require "luamidi" </source>

See luamidi syntax for full syntax.

Examples

Example for getting a message <syntaxhighlight lang="lua"> 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 </source>

Example for sending a message <syntaxhighlight lang="lua"> 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 </source>

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
