Rediscovering Microsoft’s Oddball Music Generator From The 1990s

August 14, 2025 by Lewin Day 7 Comments

There has been a huge proliferation in AI music creation tools of late, and a corresponding uptick in the number of AI artists appearing on streaming services. Well before the modern neural network revolution, though, there was an earlier tool in this same vein. [harke] tells us all about Microsoft Music Producer 1.0, a forgotten relic from the 1990s.

The software wasn’t ever marketed openly. Instead, it was a part of Microsoft Visual InterDev, a web development package from 1997. It allowed the user to select a style, a personality, and a band to play the song, along with details like key, tempo, and the “shape” of the composition. It would then go ahead and algorithmically generate the music using MIDI instruments and in-built synthesized sounds.

As [harke] demonstrates, there are a huge amounts of genres to choose from. Pick one, and you’ll most likely find it sounds nothing like the contemporary genre it’s supposed to be recreating. The more gamey genres, though, like “Adventure” or “Chase” actually sound pretty okay. The moods are hilariously specific, too — you can have a “noble” song, or a “striving” or “serious” one. [harke] also demonstrates building a full song with the “7AM Illusion” preset, exporting the MIDI, and then adding her own instruments and vocals in a DAW to fill it out. The result is what you’d expect from a composition relying on the Microsoft GS Wavetable synth.

Microsoft might not have cornered the generative music market in the 1990s, but generative AI is making huge waves in the industry today.

A Modern Version Of Famous, Classic Speaker

July 25, 2025 by Bryan Cockfield 12 Comments

Modern musicians may take for granted that a wide array of musical instruments can either be easily connected to a computer or modeled entirely in one, allowing for all kinds of nuanced ways of creating unique sounds and vivid pieces of music without much hardware expense. Not so in the 1930s. Musicians of the time often had to go to great lengths to generate new types of sounds, and one of the most famous of these was the Leslie speaker, known for its unique tremolo and vibrato. Original Leslies could cost thousands now, though, so [Levi Graves] built a modern recreation.

The Leslie speaker itself got its characteristic sound by using two speakers. The top treble speaker was connected to a pair of horns (only one of which produced sound, the other was used for a counterweight) on a rotating platform. The second speaker in the bottom part of the cabinet faced a rotating drum. Both the horns and drum were rotated at a speed chosen by the musician and leading to its unique sound. [Levi] is actually using an original Leslie drum for his recreation but the sound is coming out of a 100-watt “mystery” speaker, with everything packaged neatly into a speaker enclosure. He’s using a single-speed Leslie motor but with a custom-built foot switch can employ more fine-tuned control over the speed that the drum rotates.

Even though modern technology allows us to recreate sounds like this, often the physical manipulation of soundwaves like this created a unique feeling of sound that can’t be replicated in any other way. That’s part of what’s driven the popularity of these speakers throughout the decades, as well as the Hammond organs they’re often paired with. The tone generators on these organs themselves are yet another example of physical hardware providing a unique, classic sound not easily replicated.

An Adaptive Soundtrack For Bike Tricks

June 22, 2025 by Aaron Beckendorf 7 Comments

If you’ve put in all the necessary practice to learn bike tricks, you’d probably like an appropriately dramatic soundtrack to accompany your stunts. A team of students working on a capstone project at the University of Washington took this natural desire a step further with the Music Bike, a system that generates adaptive music in response to the bike’s motion.

The Music Bike has a set of sensors controlled by an ESP32-S3 mounted beneath the bike seat. The ESP32 transmits the data it collects over BLE to an Android app, which in turn uses the FMOD Studio adaptive sound engine to generate the music played. An MPU9250 IMU collects most position and motion data, supplemented by a hall effect sensor which tracks wheel speed and direction of rotation.

When the Android app receives sensor data, it performs some processing to detect the bike’s actions, then uses these to control FMOD’s output. The students tried using machine learning to detect bike tricks, but had trouble with latency and accuracy, so they switched to a threshold classifier. They were eventually able to detect jumps, 180-degree spins, forward and reverse motion, and wheelies. FMOD uses this information to modify music pitch, alter instrument layering, and change the track. The students gave an impressive in-class demonstration of the system in the video below (the demonstration begins at 4:30).

Surprisingly enough, this isn’t the first music-producing bike we’ve featured here. We’ve also seen a music-reactive bike lighting system.

When Wireless MIDI Has Latency, A Hardwired Solution Saves The Day

June 7, 2025 by Lewin Day 14 Comments

[Moby Pixel] wanted to build a fun MIDI controller. In the end, he didn’t build it just once, but twice—with the aim of finding out which microcontroller was most fit for this musical purpose. Pitted against each other? The ESP32 and Raspberry Pi Pico.

The MIDI controller itself is quite fetching. It’s built with a 4 x 4 array of arcade buttons to act as triggers for MIDI notes or events. They’re assembled in a nice wooden case with a lovely graphic wrap on it. The buttons themselves are wired to a microcontroller, which is then responsible for sending MIDI data to other devices.

At this point, the project diverges. Originally, [Moby Pixel] set the device up to work with an ESP32 using wireless MIDI over Bluetooth. However, he soon found a problem. Musical performance is all about timing, and the ESP32 setup was struggling with intermittent latency spikes that would ruin the performance. Enter the Raspberry Pi Pico using MIDI over USB. The hardwired solution eliminated the latency problems and made the controller far more satisfying to use.

There may be solutions to the latency issue with the wireless ESP32 setup, be they in code, hardware configuration, or otherwise. But if you want to play with the most accuracy and the minimum fuss, you’ll probably prefer the hardwired setup.

Latency is a vibe killer in music as we’ve explored previously.

Unreleased Amiga Hardware Plays MP3s

May 25, 2025 by Bryan Cockfield 33 Comments

The MP3 file type has been around for so long, and is supported by essentially all modern media software and hardware, that it might be surprising to some to learn that it’s actually a proprietary format. Developed in the late 80s and early 90s, it rose to prominence during the Napster/Limewire era of the early 00s and became the de facto standard for digital music, but not all computers in these eras could play this filetype. This includes the Amigas of the early 90s, with one rare exception: this unreleased successor to the A3000 with a DSP chip, which now also has the software to play back these digital tunes.

The AA3000, developed as a prototype by Commodore, was never released to the general public. Unlike the original A3000 this one would have included a digital signal processing chip from AT&T called the DSP3210 which would have greatly enhanced its audio capabilities. A few prototype boards did make it out into the hands of the public, and the retrocomputing scene has used them to develop replicas of these rare machines. [Wrangler] used one to then develop the software needed for the MPEG layer 2 and 3 decoder using this extra hardware, since the original Amiga 3000 was not powerful enough on its own to play these files back.

If you want to follow along with the community still developing for this platform there’s a form post with some more detail for this specific build (although you may need to translate from German). [Wrangler] additionally points out that there are some limitations with this implementation as well, so you likely won’t get Winamp-level performance with this system, but for the Amiga fans out there it’s an excellent expansion of this computer’s capabilities nonetheless.

3D Print (and Play!) The Super Mario Tune As A Fidget Toy

April 4, 2025 by Donald Papp 34 Comments

[kida] has a highly innovative set of 3D-printable, musical fidget toys that play classic video game tunes. Of course there’s the classic Super Mario ditty, but there’s loads more. How they work is pretty nifty, and makes great use of a 3D printer’s strengths.

To play the device one uses a finger to drag a tab (or striker) across the top, and as it does so it twangs vertical tines one-by-one. Each tine emits a particular note — defined by how tall the thicker part is — and plays a short tune as a result. Each one plays a preprogrammed melody, with the tempo and timing up to the user. Listen to them in action in the videos embedded just under the page break!

There are some really clever bits to the design. One is that the gadget is made in two halves, which effectively doubles the notes one can fit into the space. Another is that it’s designed so that holding it against something like a tabletop makes it louder because the surface acts like a sounding board. Finally, the design is easily modified so making new tunes is easy. [kida]’s original design has loads of non-videogame tunes (like the Jeopardy! waiting theme) as well as full instructions on making your very own versions.

Fidget toys are a niche all their own when it comes to 3D printed devices. The fidget knife has a satisfying snap action to it, and this printable linear toggle design is practically a fidget toy all on its own.

Laser Harp Sets The Tone

March 20, 2025 by Bryan Cockfield 16 Comments

In many ways, living here in the future is quite exiting. We have access to the world’s information instantaneously and can get plenty of exciting tools and hardware delivered to our homes in ways that people in the past with only a Sears catalog could only dream of. Lasers are of course among the exciting hardware available, which can be purchased with extremely high power levels. Provided the proper safety precautions are taken, that can lead to some interesting builds like this laser harp which uses a 3W laser for its strings.

[Cybercraftics]’ musical instrument is using a single laser to generate seven harp strings, using a fast stepper motor to rotate a mirror to precise locations, generating the effect via persistence of vision. Although he originally planned to use one Arduino for this project, the precise timing needed to keep the strings in the right place was getting corrupted by adding MIDI and the other musical parts to the project, so he split those out to a second Arduino.

Although his first prototype worked, he did have to experiment with the sensors used to detect his hand position on the instrument quite a bit before getting good results. This is where the higher power laser came into play, as the lower-powered ones weren’t quite bright enough. He also uses a pair of white gloves which help illuminate a blocked laser. With most of the issues ironed out, [Cybercraftics] notes that there’s room for improvement but still has a working instrument that seems like a blast to play. If you’re still stuck in the past without easy access to lasers, though, it’s worth noting that there are plenty of other ways to build futuristic instruments as well.
