Free amazing musical instrument software for windows

This was what I was trying to make when I made OpenGL Mistake No.2... Its a very simplistic attempt to create a visual equivalent to a musical instrument (and isnt necessarily successful).
Basically, this is a little project that evolved out of my PhD research - where Im trying to create a musical instrument where the sound output is intimately connected to visual output.
In doing this, I had the thought of creating a visual equivalent to a musical instrument - i.e. something that creates an abstract visual output in the same way that (traditional) musical instruments create abstract audio output (meaning the sound/visual doesnt automatically make you think: "thats a picture of a building" or "thats the sound of a car").
Anyway, it doesnt do much - its just a wee test program, but I think its pretty cool, and I think theres a lot of further exploration possible in terms of creating interactive, realtime visual instruments.

AmazingMIDI is a WAV to MIDI converting tool used in music transcription.
AmazingMIDI automatically transcribes music, converting WAV files into MIDI files. It can recognize single-instrument polyphonic music. Its a powerful tool to help you to transcribe music, to practice musical instruments and to make MIDI files, and so on.
AmazingMIDI creates an Output File (.mid) from an Input File (.wav) that contains musical data, and a Tone File (.wav) that consists of monotone data. AmazingMIDI analyzes the Input File, assuming that every sound in the file is played with the same tone color as the one in the Tone File. As a result, even if the music contains several different instruments, AmazingMIDI writes down all detected notes as a single-instrument music.
The quality of music recognition depends on the tone color of the music. AmazingMIDI is suitable for analyzing the precise-frequency attenuating sounds like piano or guitar. The drum sound becomes only noise.
Currently, automatic music transcription has no substantial solution in general, but with some restrictions of the domain, it can be both possible and useful. AmazingMIDI is one of these systems, and is still in its infancy. However, again, its a powerful chord analyzer.
