Open Source C# MIDI Software

Midi Sheet Music is a free program that plays MIDI music files while highlighting the piano notes and sheet music notes. Works on Windows, Mac OS X, and Ubuntu Linux.

This app helps you to play and improvise chords whilst a MIDI file or audio source is being played. It does this by updating a rolling display to map the chord notes to a piano keyboard. It can also dynamically assign notes or chords to keys on a MIDI or PC keyboard. Synchronisation is achieved automatically from a MIDI file. An audio file (e.g. MP3) can be synchronised and saved using the program. Chords and major/minor keys can be extracted from the MIDI file using a configurable tool that analyses the MIDI file. Chords, keys, and time signatures can also be created or updated manually - this allows you to play along with an audio source without requiring a MIDI file. The program contains a sequencer-style display that can be used to control the volume, panning, muting, solo'ing and patching of the tracks of the MIDI file. Audio can be rendered with the program's builtin synthesizer (using SoundFonts), or an external synthesizer.

microDrum is the most economical and simple way to build MIDI drum trigger. It’s based on Arduino and can be used with a huge variety of e-pads / e-cymbals, up to 48 inputs! The output can be sent to a PC and converted to drum sounds through VST like BFD, Addictive Drums and Superior Drummer, etc. … The accompanying software allows features not found in any similar solution: a direct interface with VST (without USB-MIDI cable), record, playback of tablature to practice on, etc. … This is a Open Hardware product made in Italy!
