Open Source Python MIDI Software for Windows

A2M (Audio To MIDI) is a simple desktop tool for transcribing local audio files into MIDI files with one click. It is designed primarily for piano music transcription and works best on solo piano recordings. Using A2M is straightforward: Select an audio file, click Convert, and the application generates a MIDI file automatically in your Downloads/A2M folder. All processing is done locally on your device, no uploads, no accounts, and no telemetry. The app runs on CPU by default, with optional NVIDIA GPU acceleration for faster conversions.

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.

Splits and converts your MIDI files to tablatures or sheet music for a wide range of diatonic harmonicas.

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.

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.

Implementation of Yamaha's MIDI control protocol for their digital consoles.

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.
