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.

My Theremin for 2 Persons Using Kinect Invented by the Russian professor Leon Theremin, the original theremin was one of the first electronic instruments. I always wanted to have an instrument that you can play with your whole body. The idea was to create a digital apparatus that can be influenced by the movements of 2 or more persons, interacting with each other through musical 'sentences'.The kinect is the ideal system to realize such an idea. It is programmed in C# using the Microsoft Kinect SDK. The system consists of two parts, one that translates the positions of the hands into musical values and one that sends out midi signals separated by different channels (midi channels 1 - 4, in this case). The signals were routed by an internal midi-router like LoopBe and sent to any softsynth. If you put your arm against the side of your body, the music stops. The more you lift your arm, the higher the tone. If you leave your arm in that position, the tone stays on.
