Software in this category are no longer available (at least I couldn’t find them) or don’t run on Windows 10. If you have a computer running an older Windows flavor (pre-Windows 7), you may be able to use them… granted that you find them first. The following notes were written more than ten years ago, so they are as old as the software they describe. Do not take them as current and valid.
Make Prime Music 98 ~ v22.214.171.124b
author: Armand Turpel
This program creates midi files from prime numbers. Just input a prime number and a new MIDI file will be automatically created and saved to your hard disk or wherever you installed the program. You can change some parameter values (tempo, volume, size, note range, method, instruments and some more) modifying the mpmusic.ini file. Run in a windowed DOS session.

Mandelbrot Music Program
author: Yo Kubota
Explore the Mandelbrot set while the iteration values are transformed into music by a composition rule. MIDI files and their corresponding ini files (where parameter values are stored) are automatically saved every time you compose a new melody. 16-bit and 32-bit versions available.

MusiNum ~ v2.08b
author: Lars Kindermann
MusiNum turns integer numbers into musical notes (including chaos, fractals and self-similarity concepts). Each voice channel is presented in a different window, making it easier for beginners to work with all available options and instruments. This new version adds better script capabilities, more midi devices, and file association. Great program.

Project Oblivion ~ v1.27a
Oblivion uses various random number algorithms and attempts to pull from a collection of random numbers musical sounds to make its compositions. The resulting files can be saved as MIDI and .obv format. You can also modify several options available directly from the main screen.

Quasi Fractal Composer ~ v2.01
author: Paul Whalley
This is another interesting algorithmic music generator full of surprises. It is similar to MusiNum, but with one single interface. It has several saving options (for midi, scale, orchestration and composition).

Venharis ~ v1.0
author: Phil Thompson
Combining a gaming interface with a powerful fractal music generator, expect the unexpected with this software, since its interface is very unique. It’s not plain software; it’s an interactive experience that would let you create some fractal compositions while you experiment with it. Requires a 3D video card and DirectX 7.0 or later.

Well-Tempered Fractals ~ v3.0
author: Robert Greenhouse
This program composes musical melodies by mapping fractal images to musical scales. Ten different fractal types, including Julia, Hopalon, KAM Torus, Chevychev, Ikeda and Mira, may be mapped to twenty-one different musical scales. Twenty symmetry operators may be applied to the image as it is plotted. The output may be directly heard or written to a MIDI file. Runs quite well in Win9x (DOS full screen). Alternate site.
