[released] Masterpiece Generator - No AI, No Samples: 8-Track Algorithmic Groovebox

[mike_mgen_fun]

Hi!

The app is now available:
https://mgen.fun

This is an algorithmic groove generator designed for fast idea generation — controlled randomization produces musical results with an effectively infinite number of groove, bass and lead combinations, making identical patterns impossible.

The goal is simple: generate usable, musical patterns — not random noise.

No AI.
No samples.

Each track has its own internal synth with independent parameters, allowing full control over sound design per track.

Core features:
– built-in synth engines (drums, bass, leads) with per-track parameter control
– deterministic random engine (Seed + Chaos control)
– randomization works both globally and per track: you can generate everything at once or randomize patterns, synth parameters, FX and p-locks independently
– scale-aware note generation (root + mode)
– step sequencer with per-step control (note, probability, accent, slide) + Euclidean rhythms
– per-step parameter locks (p-locks)
– 4 FX effects
– MIDI out with per-track routing and per-step CC (CC locks)
– song mode with pattern chaining
– export pattern and song to WAV / MP3 / MIDI

Performance:
– written in Rust
– low CPU usage
– ~160 MB RAM usage

Everything (patterns, synth parameters, FX, p-locks) can be generated together or independently, depending on the workflow.

Looks cool. Pricing?

[wagtunes]

If it's standalone, how do we actually use it in our DAWs to make songs?

[Tiles]

Midi maybe.

[mike_mgen_fun]

7 days trial, then buy forever and all future updates 8.99 USD. The release is in April, it remains to resolve issues with apple and correct the sound in some places.

This is a standalone application — you can use it with any MIDI synthesizers.
If you want to work in a DAW, you can export the entire track as MIDI and assign your own instruments there.
I may consider deeper DAW integration in the future if there’s enough demand.

So I create the track standalone and then export the MIDI to my DAW and assign the instruments I want there. Okay, it's an extra step but not a deal breaker. I have several things I do when making songs that require me to go outside my DAW so this won't be the first time.

I'm willing to give it a go as long as there is a demo so I can just make sure it will work on my system. Sounds like an interesting concept and might generate some interesting results.

Looking forward to the release.

[mike_mgen_fun]

Yes, that's right. Therefore, there will be a trial version for a whole week to try out all the functionality.

generate usable, musical patterns — not random noise

To be honest: for me your example videos sound more like what it should NOT be

I wonder if there is/you will make any styles so that you can get something that while comparing with that kind of style really "generate usable musical patterns" ?

Yeah, that makes sense.

I’m basically trying to balance musicality and variation. If I push too hard on constraints, it starts sounding “correct” but also more predictable, which isn’t really what I’m aiming for.

The idea is more about generating interesting starting points rather than finished tracks — something you can react to and shape further.

Still figuring out where that balance should be.
If you’re curious, there are ~28 audio demos on the site, all generated by the system.

I listened to the demos and I think I get your idea but the demos dont really change my impression. And on the background of whats already out in this corner (AI and simple "generative", felt evryday something new comes out) for me an absolute necessary requirement would be to have the option of targeting something musical and that would include at least some "styles" or whatever you might call it.

Especially as you have already included the option of making complete songs. What songs ? Hip Hop, Trap, Rap, Pop, Ambient (my corner), R&B or I dont know all the new stuff where I am too old to even know the names . At least some starting points of the main general styles (lets say the ten you can find in any AI generator...).

And: especially as it could not even be integrated simply (as most of the other midi generative stuff I am referring to) as vst but you have to use standalone. So: if standalone song generator it should at least generate some "songs"

Yeah, I get what you mean.
Right now the focus is more on generating raw material rather than targeting specific styles. I’ve intentionally avoided fixed styles so far, because they tend to make the output more predictable and reduce variation quite quickly.

The idea is more to generate something you can react to and shape further, rather than complete genre-specific tracks. That said, I’m exploring ways to introduce some structure or direction without turning it into a preset-based system.
I went with standalone first to keep it usable outside of a DAW, but I’m also considering VST integration.

Appreciate you taking the time to listen and give detailed feedback.

[Seluvis]

The idea of working outside of a daw can sometimes produce good results, to focus on one thing alone before moving on. I am not going to lie this project looks solid.

[tatanka]

This. The styles where only one example how this might be done the easy way. And "presets" not intended but "direction".

For me the examples mostly sound without any direction. So I could hardly imagine for me (might be my personal workflow only) to get a start with this the way it is.

This might work for a drumsequencer only (what is of course one of the main parts of it) but to get a starting song idea out of complete randomness....
