MIDI Master Clock: Simple MIDI Song and Control Change Manager MIDI Master Clock is a lightweight, command-line utility for effortless MIDI device control and synchronization. It lets you define songs or cues in a simple text file, each with its own BPM and custom MIDI Control Change (CC) messages. What It Does: Reads Song Data: Configure song titles, BPM, and MIDI CCs (e.g., CC_ch0 10) in an easy-to-read data.txt file. Interactive Control: Select songs from a list, advance through your set, or quit, all from the command line. Automated MIDI Commands: When you select a song, MIDI Master Clock automatically sends: - All specified MIDI Control Changes (CCs), ideal for triggering effects or states. - MIDI Sync Commands (Stop, Song Position Pointer (0), Start) to prepare your devices. - Accurate MIDI Clock signals based on the song's BPM, keeping your gear perfectly in sync.

vahatraker is a MIDI sequencing companion for GNU/Linux audio setups. Adhering to Unix philosophy, driving MIDI is the one thing it tries to do well, adhering to other doctrines - enabling expression, with added value of: - live editing - fast workflow - intuitive midi-in - unheard of time signatures - scenes a'la 'ton - fractal turtles - fits on a floppy - doesn't make sound Frankly speaking, vht was envisaged as a re-creation of seq24 in tracker form for author's "studio needs" and offers similar functionality (and limitations). It relies 100% on JACK audio connection kit for input/output/synch and uses jack_capture for rendering. The GUI has similar dependencies as gnome-calculator and tracker paradigm was chosen to allow for rhythmic gymnastics otherwise hard to convey. Low level stuff was done in C and wrapped in Python. Human interfacing part of contraption employs GTK through gobject introspection and was also contrived in the language we shall no longer spam abo

Canorus is the next generation music score editor. It is the official successor of NoteEdit. It uses Qt4, has scripting capibilities and uses modern development standards like eclipse, patterns and test units as base.

Aldrin is an open source modular music sequencer/tracker for the GNU/Linux operating system. Aldrin is currently in beta stage and fully functional. Feel free to try and use it.

A graphical editor for GENPO organ description files. It allows the user to create divisions (keyboards), select stops from a SoundFont file or an existing GENPO file, assign the stops to divisions, rename them, copy them, etc.

Modular portable graphical based music editor. A new concept loosely based on the tracker-interface. Aimed to be used by both amatours and serious composers. Status for AmigaOS is stable, status for Unix is pre-alpha.

The MIDI Sight Reader Java Applet works again! To use it you should use Firefox with Java Applet Plug-in installed. Developed using Firefox 25.0.1 and Java 7, Update 51. So what is it? Well it scrolls random notes within a selected key, playing them aloud for audio confirmation, while you, the user, play the notes on your instrument. There is no MIDI interface, the name refers to MIDI because it uses the Java Midi API and organizes everything numerically, according to MIDI numbers. The application plays the notes aloud as they pass under the centerline of the application window. So you adjust the scrolling speed and time between new notes and then play each note before the application echos it back to you. It also scrolls guitar tablature, as can be seen in the video. The keyboard and guitar models are linked so that playing a note on the piano keyboard (clicking a key) causes the guitar neck to display all the locations of the same note on the guitar neck.

Strasheela is a constraint-based music composition system. The user defines music theories by sets of compositional rules and the system creates music which complies with these theories. User-interface is the programming language Oz.

Analyzer for Files (AoF) is a tool to look into file contents, analyze the structure with installed plug-ins, and show the results with several split windows including converted data and a tree if successful. It was designed as a workbench with a core and plug-in extensions. It can handle the normal plain-text file and data, complex binaries supported with the corresponding plug-ins. What's more, the developers can deploy and release their own plug-ins according to the plug-in developing standard. The development site is https://bitbucket.org/cadappl/anafile.
