Building a browser-based techno pattern generator for trackers

Hey everyone,

For the past year I’ve been working on a tool I think many tracker-based techno producers will enjoy.

It’s a pattern generator that runs right in your browser, built for tracker format from the ground up. The goal is simple: make it fast to create rhythms and just as fast to drop them into your tracker.

The bassline engine got the most love. I’ve been tweaking and improving it for almost a year. It’s not random notes, these are patterns shaped to actually work in a track.

I first made it as a C++ desktop app for myself. Later I decided to bring it to the browser so anyone can use it without installing anything.

This is not just a randomizer, it’s a polished, battle-tested algorithm I’m finally ready to share.

Stay tuned. Your feedback will help me finish it faster and open it up to everyone.

That’s pretty cool! How are you porting it to the browser? Just using the regular Web Audio API or are you using a specific library?

I’m currently playing around with Elementary Audio myself.

:rocket: The Tracker Techno Pattern Generator.

For the last months I’ve been deep into trackers and hardware jams, constantly building loops, testing ideas, and hitting walls where inspiration would stall. One night I thought: what if patterns could generate themselves, instantly, in a format that feels natural for a tracker? That thought pushed me to create this tool.

The Pattern Generator is simple: hit random, and you get ready-made sequences for kicks, claps, hats, percussion, bass, and FX. What I love the most is how it spits out basslines - sometimes minimal, sometimes hypnotic, sometimes completely unexpected. It feels like the machine is jamming back at you.

It runs right in the browser. No downloads, no installs. You can see the pattern, hear it, copy it, and move it into your tracker in minutes. Perfect for quick inspiration, live set experiments, or just to break out of the same old habits.

And yes - it’s free. I just wanted to share it with people who live inside this same grid.
