This now means Code Pens can now become powerful synthesisers... codepen.io/samaaron/pen...

As of v0.21.6 SuperSonic now works directly from CDN - no special headers are needed - which makes deployment *dramatically* easier. There's now two modes: 1. The original SAB (SharedArrayBuffer) mode which is *marginally* faster and less jittery - but requires stricter security 2. SAB-free mode.

From teaching code through music to live, collaborative systems where humans and AI improvise together - watch @samaaron.bsky.social keynote's to explore rhythm, concurrency, and what it truly means to work in time, not just at the same time.

I just pushed v0.18.1 of SuperSonic to both GitHub and npm. This feels pretty much like a v1 release. I'm holding off tagging it as such as I want to give it more time to bake and subject it to some serious usage. Please take a look and let me know what you think. sonic-pi.net/supersonic/d...

I'm strongly considering starting a series called "Couch to Sonic Pi" where I gradually build a web version of Sonic Pi using SuperSonic. Episode #1: play and sleep (It currently clocks in at just 80 lines of html/js) Each episode would include a Post + Video + Git Commit What do you think?

Sam Aaron introduces Tau5. The motor block and frame for what will hold a new sound engine and beyond that do things Sonic Pi never could. Doubling down on Elixir. Sam did speak twice at the conference so more to come! goatmire.bold.video/v/4e68e #goatmire #elixirlang

SuperSonic now exposes the scsynth node tree for fast reading from JS. This does not require a full OSC round-trip like /g_queryTree (which is also supported for legacy use cases). Instead it’s automatically written to the SharedArrayBuffer so visualisers can read it at 60fps without issue.

What defines a correct program? What education makes a good programmer? The answer depends on what culture of programming you subscribe to! This has been a long time in the making, but my open access book on the history of programming is available for pre-order! www.cambridge.org/core/books/c...

. @samaaron.bsky.social asks: imagine if writing were only for business. We treat programming that way. By pairing code with music, he shows kids that coding is a creative language, not just a utility.

Last session of the day is a musical performance and talk from @samaaron.bsky.social with Sonic Pi. #YOW25

Live coded music at #YOW25 with @samaaron.bsky.social Awesome!

Not the same thing, but a few years back at the Elixir conference in London there was a talk and performance by Sam Aaron, creator of Sonic Pi and it was amazing

Absolutely loving the new album “Instant Holograms on Metal Film” by @stereolabgroop.bsky.social The music is so on point and the lyrics movingly poignant. Highly recommended!

Crikey, SuperSonic just passed 100 stars on GitHub. That was quick! Thanks so much for all the amazing enthusiasm and support. It means a lot. github.com/samaaron/sup...

Tomorrow I’m off to Australia! See you down under :-)

A mild warning... now my home renovation is complete, I'm no longer on the edge of financial calamity, and my brain is back functioning again... ...I'm going to continue getting louder, more productive and ship even more ground-breaking software than I ever did before. Let's go!

New Patreon Post: v0.10.0 of SuperSonic is Released. From Experimental to Engineered. In this post I discuss why it's such a significant milestone and what it took to convert an experimental prototype to an engineered system. www.patreon.com/posts/supers...

Huge props to James McCartney who created SuperCollider. In my humble opinion James is the OG live coder having built the first well-used live programming environment for music making. (Obviously nobody is truly the first of anything - and those that claim it are just posturing.)

I just released version 0.10.0 of SuperSonic - my web port of the powerful SuperCollider audio synthesiser. It's feeling *really* good now, and I definitely think it's ready for people to start exploring. Have a play and let me know what you think! sonic-pi.net/supersonic/d...

New Patreon post: 2025 Financial Update. www.patreon.com/posts/2025-f...

I spent over 3 months working full-time on a web port of SuperCollider’s powerful synth engine. Just to add the best audio capability to Tau5. If that’s not a clear sign that I’m in it for the long haul, I don’t know what is. Follow me on Patreon for the latest updates: patreon.com/samaaron

Circles by Adam F is still a total banger. Check, check, check, check.....

SuperSonic - my port of SuperCollider’s powerful synthesis engine scsynth now has improved metrics - opening up a window to the internals. Play with the demo and see for yourself! sonic-pi.net/supersonic/d...

I just pushed 0.4 of SuperSonic - my web port of SuperCollider's powerful audio synthesis engine for the web. sonic-pi.net/supersonic/d... Hopefully you'll have a lot of fun playing with the demo and it will leave you with a strong sense of wanting more. That more will be Tau5...

Tau5 just made its first sound. It was the Amen Break... followed immediately by me shouting for joy and leaping around the room.

This is the full SuperCollider synth running in a browser, high-performance and with an OSC API. Hard to overstate how powerful that is, and it's just the beginning.. Incredible work by @samaaron.bsky.social ... cdm.link/supersonic-s...

I totally get and respect that not all programmers want to use LLM agents in their work. However, if you're against other people choosing to use them you're just a gatekeeper.

I updated the SuperSonic example to include synths, samples and FX and a fun playful interface. SuperSonic is my port of SuperCollider’s extremely powerful scsynth engine to Web AudioWorklets so it can run in the browser. Play with it here: sonic-pi.net/supersonic/d...

OMG OMG - I just managed to play a pre-recorded sound in SuperSonic, my port of SuperColliders's audio engine scsynth to the web. Looks like there's a bug in scsynth which only revealed itself in WASM in a hideously nefarious way that wasn't obvious in the slightest and took a week to figure out...

IMPORTANT: The Dutch invest €595 million annually on urban biking, resulting in €19 BILLION saved in public health care costs alone. That’s how smart governments do the math on investing in better mobility. Let’s be clear— it wastes public money to NOT do it. #CityMakingMath HT @modacitylife.com

Pretty sure I’m going to release my self-nerd-snipe project tomorrow. One of the coolest aspects of it is that it runs in RTNRT mode (really it does). (Where R=real, T=time and N=none).

I totally and utterly nerd-sniped myself for the past month working on something I wasn't sure I could do or was possible. I think I've done it. It feels a bit surreal. If things turn out as good as they're currently looking it's going to be a game changer for both Sonic Pi and Tau5.

I’m still thinking about @samaaron.bsky.social’s talk at #goatmire - nothing has captured my curiosity and wonder for coding like this! #elixirlang

Waking up with @samaaron.bsky.social at #Goatmire is a pleasure

Today was a nice milestone for Tau5. The GitHub CI now auto-builds a fresh Linux AppImage for each commit. I was able to download the latest ARM64 AppImage as a single file and run it on my Raspberry Pi - simply by launching it. It worked :-)

Tau5's internal server has 3 optional configurable http endpoints: 1. Local - listening to localhost (for trusted interactions) 2. Public - listening to external machines (for untrusted users) 3. MCP - listening on localhost (gives AI agents access to a secure sandboxed Lua runtime). tau5.live

Tau5 isn't just another fun language for live coding. It's a secure cross-platform-runtime designed to support many fun languages *working together* for live coding. tau5.live
