A downloadable game for Windows

Hello everyone, a long time ago I made this thing, "Dunc's Algomusic", which makes random music. People occasionally ask me if it is still available, so here it is.

There are two versions, Mk III and Mk V. They each have a different feel. In both you can press 'n' and type in a title, it will generate a song from that string.

I also don't remember why they were called "Mk III" and "Mk V", when there's only two of them, except to say that I was quite fond of Steve Jackson Game's OGRE.

Mk V

"Mk V" was written in Blitz Basic (I've made the sourcecode available too).


First of all, thank-you to Gunship_Mark_II at the Vinesauce Reddit for making this available, as I had lost my original.

Mk III's claim to fame is that Stuart Ashen used it to make the "Ashen Theme Tune". It was written in, good grief, Dark Basic, and I cannot honestly remember how it got on the internet in the first place. Since people still upload videos of it to YouTube, it must be circulating out there somewhere.

Make a new one!

If there's interest (vote with your donations!) I might look at making a new version in Python.

Mk V sounds awful?!

Try replacing the wave files in the music folder, I guess?

Thinking about a new version, there are Python modules for creating MIDI, and modules for playback. I don't think I can create and play MIDI on-the-fly. That would mean 1) It won't play endlessly. 2) There will be a delay before music starts playing (as it generates the track). Personally, I like that AlgoMusic plays endlessly and plays new titles immediately. What to do?

I would like to have something with higher sound quality. Maybe you could upload it as a separate program so you could choose to have both?

As in higher sample rate, or the sound mix (or both)?


I meant sample rate, but a larger collection of sound files for more diverse songs would be pretty sweet too.

What are the usage rights for this software?

I've made them public domain. If you use or distribute it, attribution and link here would be nice of course!

Do the songs continue endlessly? I've been sitting here listening to the same song for 2 hours

They will go on endlessly.

I think Mk V crashes after a while.

Is it possible to save the generated music?

Not directly. I used to use Audacity to record the audio output, so I recommend that. If you just want to save to play in AlgoMusic later, all you need is the name of the song.

Hi there. I was the anonymous source code requester.

I wanted to ask, are you absolutely sure there's no way to find the Dark Basic Mk III source code? I really like reviving old apps, and it would be cool to see how it worked.


When I checked my backup CDs, I only had some stuff from Dark Basic Pro (which I got after DB). We're talking 10 years ago here, I've changed computers 5 times since then and had several backup HDs fail... I will scour them again though!

From what I can remember, Mk III used little pre-fab melodies of 2 to 4 notes to create a "base" section. It would change this over time but occasionally return to the original. As you might be able to tell from the tracker, it can create variant sections that it cycles through, and some channels echoed others, and it throws in random chord changes. The name of the song is the seed for the RNG.

Mk V ditched the pre-fab melodies and tries to make its own, the result is more experimental and less catchy, which might be why Mk III is more popular.

Yeah after HOURS of trying, I simply cannot get this to run on my windows 10 machine WHAT SO EVER. All ive noticed is that for some reason it wants to keep itself as read only, but only on the top folder level, files in it are still fine. I tried allowing access through DEP, Through the Firewall, gave it every permission feasable next to god system access and even did a SFC scannow to make sure all my dll's were in order. Thats a giant bummer because this is the best rig i have to be able to record footage and id like to make some youtube vids or something in good quality.

My only guess is that the new cpu's or hardware simply dont have the old tech in it to process this.

Are you planning to add an export feature for MIDI? I would love to be able to modify these results and use them for stuff :D


Not for these versions, no, the languages I used didn't haven't native MIDI support.

If I do make a new version, it will be in Python, I'm sure there's plenty of modules to support MIDI

Ok. Thanks!

I tried to use these, it wont work at all, I allowed the exception in the DEP settings (you physically cannot turn it off in windows 10, just allow exceptions) and even used several compatibility settings and nothing.

(sorry for the multiple posts, the page kept saying it was having server trouble and didnt look like it posted )

I'm not sure if it's a compatibility issue, as they both run okay on my Windows 10 computer without changing any compatibility options. Can I make sure (and sorry if these are dumb questions), is it all unzipped, and are the subfolders present (/music for Mk V, /wavC etc for Mk III)?

(Edited 2 times)

Well im using the itch.io app which automatically downloads and installs the game to a folder so it extracts it. I also downloaded them seperately and unzipped them. v5 just has the music folder next to the .exe with a text readme file. Also you should delete the readme as the page http://www.wikihost.org/w/doodleblog/dunc_s_algomu... leads to what could potentially be virus laiden websites, it attempts to load several redirected websites which my chromium blocks.

the v3 includes several folders, drum, wavC, wavE,wavG DAM.txt and the duncalomusic.exe. Ive also used 7zip to extract the .exe within the extracted folder just for kicks and still have nothing. Ive added the programs to my exception in the DEP settings, and ran the .exe in every compatibliity mode i can think of. I have windows 10 pro 64bit. nvidia 1050ti, 16gigs of gskill ram, and an i5-2500. And yes i know its just a small text based thing, but still wanted to post the specs just in case.

Oh the error i get is "this application was unable to start correctly (0xc0000022). Click OK to close the application."

Okay, tested this on another windows 10 computer and it works. Not sure why that worked and this didnt. Do you need java installed or anything like that?

The Dark Basic and Blitz Basic compilers were both self-contained, but they are both ancient now so it's unsurprising there'll be some issues.

Thanks for pointing out the wikihost thing, that's where it used to be hosted like 8 years ago but it doesn't exist anymore. I'll update it later.

yeah i just CANNOT get it to run on my gaming rig, but my frankenstein of a computer thats a 2008 mac pro jerryrigged to run windows 10 64 bit with the xeon processors works just fine. And Im using google drive so the file is synced so its quite literally the same file and folders and works fine on one windows 10 and not the other, though my current pc is running creators update and the other isnt, I will update it and see if i lose access to the files.

After some sleuthing i found that it cannot creat the dplayx.dll for some reason C:\Windows\SysWOW64\dplayx.dll, access denied even with admin rights and given it everyone status. very weird.

That is wierd. Not much I can do about it :)
