MIDI Controller is a small program that lets you set MIDI controller values using sliders and buttons in a GTK+ window. The GUI is an XML-based Glade file which can be replaced without rebuilding the program, so you can build your own controller GUIs in Glade.
Midid is a general purpose MIDI system for Unix. The system allows you to control multiple MIDI interfaces for sequencing or other purposes.
mididings is a MIDI router/processor implemented as a Python module. It's primarily geared towards live keyboardists, but should be useful for MIDI processing in other settings as well. While the actual MIDI processing is done in C++ for speed reasons, it is possible to explicitly call back into Python, allowing you to process MIDI events any way you want.
midikb is a text mode program that sends MIDI note-on/note-off messages according to key presses on your keyboard.
This project aims to do a real-time audio note recognition software for monophonic signals (like solos). The input must be a monophonic wave signal (only one voice, with one melodic instrument). The result are MIDI events launched trough the ALSA sequencer. (recognized notes are printed to the standard output too)
Midirecord is a simple commandline application to record a midi file with your midi keyboard. It also features automatic recording to a midi file when you play electric piano (therefore it may be used as a "recording daemon").
midirgui is a simple midi router, routes midi channel messages to the specified ALSA sequencer ports for each midi channel, you can specify what ports, default output channel and midi velocity sensitivity offset for each channel.
multimidicast sends and receives MIDI from Alsa sequencers over network. It uses UDP multicast datagrams and is thus subscriptionless and plug'n'play.
It is designed to interoperate with the windows software ipMIDI.
Musical MIDI Accompaniment
Musical MIDI Accompaniment is an accompaniment generator -- it creates midi tracks for a soloist to perform over from a user supplied file containing chords and MMA directives.
NOTEMIDI is a Linux interface for MIDI output via the RS-232 serial port on notebook (laptop) computers. NOTEMIDI can be used with the MIDIator MS-124W interface, Roland Sound Canvas sound modules or Yamaha MU-x series sound modules.
Pymprovisator emulates the program Band in a Box from PG Music. You can think in it like the electronic version of the books+CD from Jamey Aebersold.
QMidiArp is a MIDI-Arpeggiator.
QMidiControl is a virtual MIDI fader box.
QMidiRoute is a MIDI router and filter utility.
qtpod is a QT application which can control your Line6 POD 2.0 and POD Pro via MIDI. Currently the ALSA midi sequencer API is supported.
Ratón translates mouse movements into MIDI controller messages. Those movements are mapped through a user-defineable curve, which can change the characteristics of the mouse's location. Changing the curve can then expand, contract or step the controller messages to match the specific purpose.
Rumor is a realtime monophonic (with chords) MIDI keyboard to Lilypond converter. It receives MIDI events, quantizes them according to its metronome on the fly and outputs handwritten-like corresponding Lilypond notation. Tempo, meter, key and other parameters can be set via command-line options.
Scheme Note is a Scheme-like music file format and MIDI conversion tool. It takes a text file, which is a representation of a song, loosely tied to a MIDI-like event structure, and outputs a corresponding MIDI file.
Shelljam is a cross-platform console application that transforms keystrokes into MIDI events and hence, lets you use your computer keyboard like any other MIDI input device.
synthclone is a Qt-based application that can "clone" your MIDI-capable instruments. It does this by sending out MIDI data that instructs an instrument to emit sounds for a series of notes, velocities, controls, and aftertouch values. It then saves this data as a sample-based instrument that can be loaded by sampler software.
SynthEd is an attempt to build a cross-platform universal editor/librarian for MIDI music synthesizers. SynthEd will leverage XML and wxPython to support synthesizers with minimal coding.
SysExxer is a small utility to send and receive system exclusive data to resp. from MIDI devices like synthesizers.
Virtual MIDI Piano Keyboard
Virtual MIDI Piano Keyboard is a MIDI event generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard or mouse to play MIDI notes. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player.
