I agree that it's neat to have software synths that can run in the browser nowadays, but this isn't really a good TB-303 emulation. The accent doesn't have a slow enough attack to create the "wow" effect, which is a fundamental aspect of getting any random acid line to sound properly 303ish. Not to take away from what it is, but for a synth that has been cloned and emulated as often as the TB-303, your description is overselling it a bit.

This is absolutely awesome. The multiple lines really make it unique.

I really never heard the enigmatic scale that much but it sounds wonderful. The only thing I would want to hear are melodic and harmonic minor modes.

This is amazing. Thanks for making it.

Hey if you don't mind updating this, can you please allow the tempo to be as high as 150 bpm?

I've just updated this to make it a little bit easier to use on a phone. The knobs are now a bit chunkier and should respond better to touch and the instruments sit vertically instead of horizontally.

Are you interested in open sourcing? I'd love to learn about how this was done.

Sorry, I'll implement it, I had forgotten we didn't do it for erm... 9 years.

This is really lush. Instantly it brightened up my evening. This kind of experimentation is always amazing to see.

As many seem to have mentioned below, it brings back memories of Rebirth in some ways. What it also reminds me of is the beautiful results you could have by plugging some simple modules together to create soundscapes. The limits are the things that provide some semblance of freedom and this is no different. Greetings from a fellow UK acid (techno) head! :P

How do I export/save a pattern I like?

this is awesome. would suggest not randomizing the tempo on regenerate, and if it was already playing, when hitting regenerate, keep it playing. that would make it easy to quickly audition loops at a given tempo with a single click

this thing is great. you got a version that can run as a vst or plugin?

Oh, that is neat! Vitling also makes nice music.

I wish I could attend! I'm in the UK.

I remember using that one time to make music for a presentation for a power point slide. We burnt the music onto a CD and brought in a boombox. I it was for my accounting class. It was kinda cool.

No, but the timekeeping part of it is. I put that code into a small library to use in my music apps: https://github.com/errozero/beatstepper

Export midi or realtime output midi.

Exporting the generated audio stems would be slick, too, rather than having to run capture on it.

I'm a little sad that the 303 sound had such a short-lived and niche life. In the 90's it seemed to me like it was the first instrument that could challenge the hegemony of the electric guitar. It was so versatile - the sound is bouncy, melodic, and had some real "growl", all at the same time.

Thank you! It's been a few years so I can't remember exactly without reading through the code but it's something like this:

It uses notes from the selected scale and octave (from the dropdowns). If the pattern is of an even length, say 16, it will split it into 4 chunks of 4, then randomly decide if it should generate new data for the chunk or copy the previous chunk. It uses the repeat slider for the probability on this.

It randomly applies the 303 modifiers (up, down, accent, slide) using probability set with the sliders on the pattern tab.

There's also an 'empty' slider which sets the probablity of an empty note appearing in a chunk.

Check out this great album, a study in acid: Filo Loves the Acid by Donato Dozzy.

Learn by imitation ; if you want to make DnB tracks, try and inevitably fail to recreate existing DnB that you admire. With time your failures-to-imitate will congeal into a novel and personal style.

You could grab some sample or instrument packs that will help you approximate the sound you are after more quickly.

Baby Audio has a pretty nice VST instrument and 90s preset pack that might have the sound you are looking for - have a listen here https://static1.squarespace.com/static/561e2985e4b08862a3496...

On a side note - if you are looking for people to help out I’d love to have a crack, also looking to learn.

This book [0] is full of great creative strategies to make electronic music, ways of getting started/unstuck, is generally not that tied to Ableton the software (even though they are the publisher), and is free to partially peruse online.

I’d recommend getting a physical copy once/if you find it useful. It’s been a really great help in getting over white page/DAW syndrome. Truly great and full of smart/useful gems.
