To break up the computer-assisted music a bit, here is a very different one composed in a more traditional fashion:

I reworked the piece above a bit to benefit it and put my program's contrapuntal technique more on display. It starts out with the input melody. Then, after it sounds once, that same melody sounds again with two voices added. Then, to bring things to a close, it sounds third time in the presence of four other voices.

This one turned out quite nice. All I did was provide a melody and specify five voices and the harmonization was determined in a purely deterministic fashion:

Whoops, I forgot to connect two of the voices to sound output. Here's the fixed version:

Reworked the above composition to harmonize with better technique. Also, added two voices so that there are now five moving in counterpoint rather than just 3.

I accidentally forgot to turn one of the voices on. Here's a better version. Note that the pitches are a bit out of range in the sense that the voices get too close together at points. It's a consequence of the fact that I'm still adjusting the parameters of the program a little:

I started a new and better program from scratch, as the one above, while necessary to create as part of a learning process, is not quite what I currently need. Here's a short and simple piece with three voices moving in counterpoint. It's short because it was a preliminary experiment to test the principles I was contemplating. I think it turned out nicely as a small proof of concept. By the way, it is not in standard 12-tone equal temperament but rather something closer to just intonation:

Fixed a major error in the program's functioning. Here's a piece to illustrate. It has several voices moving at once:

This one has a great many voices in it, and benefits from another little discovery I made about harmony:

By the way, I have long since done away with the harsh instruments of my composition program's yore. So if people are not listening because they're afraid of having their ears abused by sawtooth waves, you may rest assured that they problem has to a fair extent been corrected. The instruments are still not ideal, but they're much better than they were. How does my program work? Well, it certainly isn't one of those random generators. There is no artistic value whatsoever in randomness. No, my program is 100% deterministic. Anyone who knows what they're doing in is in position of control rather than one of letting the winds blow where they may. Basically, the program is A, a musical instrument and B, a tool for calculating good harmony and counterpoint according to certain esoteric principles that I discovered and about which no else knows anything. I use this program because I need a good instrument like any composer and because the calculations involved in properly controlling harmony and counterpoint are thousands of times too complex to perform without the aid of a tool that automates the process and does so quickly. So what do I do? I first design and input a melody. Then I enter a number, one very easy to choose, for each timestamp that turns the melody note into a full harmony that represents it and which will flow smoothly and coherently into the next harmony. Does my program work? I think it is quite clear that it does. Not perfectly--I am still improving the program--but it's certainly getting there.
