tekstar··on Show HN: Collaborative live-coding MIDI sequencers in JavaScript
Hey everyone,

I've been working on a collaborative audio, MIDI, and video editing web app for the past few years and I'm excited to show you what we’ve built so far.

Sequencer Party is a collaborative audio / midi / video web platform. It supports WebAudioModules 2 (WAM2), a third-party plugin format—like VST plugins but for the web.

The demo session linked in the post is running a live-coding Javascript MIDI sequencer plugin. Press the ‘code’ button on a plugin instance to edit the running Javascript. Hit ‘Run’ to run your code changes. If you log in, you can save your session or individual plugin presets and other users can load them into their sessions.

It’s collaborative like Google Docs. Sign up, invite people to your project, and you can edit the same session together in real-time. Without an account, you can run an offline copy, and it’s saved in your browser's local storage. When you’re in an online session, the code panel is also collaborative with everyone else in the session.

The post link goes to a public session you can clone into your own project if you sign up, but if you want to join a collaborative online session with me, here is a link to a project I made that we can hack on together:

https://sequencer.party/users/invite/1af84830884292fecb834fb...

We’ve got a lot more planned for 2023—more instruments, thousands of factory presets and sounds, run the video in a separate window for VJing or render the audio/video to a file.

Thanks for checking it out and let us know what you think! It works best on a computer (not phone) in Chrome and Firefox.

tekstar··on Ask HN: What is your opinion of “unlimited” PTO?
same experience. the only person who used it in earnest was the head of HR. For lower tier employees it was much worse than a given X number of days - they had to request the time off from their manager and could (and were) denied taking time off.

tekstar··on Tough time building components of a site using vanilla CSS. What to do?
hey just saw this, sorry - I think I watched the most recent full course for CSS and then the 2 or 3 hour course on flexbox. As well I watched the start of a few courses on website design.

I took a few courses from Lynda.com to learn more css. It helped immensely and was free with my library card.
tekstar··on You can hook your MIDI keyboard up to a website with Firefox 108
The WebMIDI standard has a problem, which is that only the main UI thread can talk to the WebMIDI devices directly. So even if you schedule your MIDI messages in the audio thread, to emit them on the hardware device you need to pass them to the main thread and then emit the messages from there, incurring whatever delays imposed by the main thread as it handles user input
tekstar··on Twitter to employees: all office buildings closed, badge access suspended
Around 2012-2015 we had someone on-call over the holidays do a redeploy every few days because of Rails memory growth at our now-IPO'd ecommerce giant.

This growth impacted every rails app back then, the popular ones more quickly is all..

This is simply not true, because Twitter algorithmically pushes content you did not subscribe to in order to drive engagement. You do not have control over what you see, and are subject to the controversial subject of the day regardless of who you follow.

So, I don't have a source to back this up, and without a source this will be worst of the rumour mill, but I'll say it anyways in case someone has a source to back it up or refute it.

A few weeks ago it was explained that Facebook is telling affected people they are no longer on the team they were on before, and they have X weeks (4?) to apply internally and find a role on a new team. So you're not fired, you just don't have a team and failed to find a new one, so.. see ya?

tekstar··on Take a break
Hey, this is me.

This is extremely privileged advice, but the only thing I managed to do to help was to have a second place to go to where I didn't work - in my case a little cabin in the woods. Going there on the weekend forces me to take breaks. If I'm at home I'm working. It doesn't help that I'm a solo founder. Work is very rewarding but it can also be all consuming. And there my piano sits untouched.

tekstar··on Software Automatic Mouth – Tiny Speech Synthesizer
I rewrote the main loop of this a few years ago to be re-entrant, so you can render N samples at a time. Synth projects wanting to use SAM should start somewhere like that probably.

I then ported it to Mutable Instruments Braids, a eurorack module:

Can you explain this more? I've been getting into home automation and my wife would like programmable irrigation for when we're not at home. Did you interface with existing wifi valves or are you doing the circuit yourself?

When I learnt about how the Texas grid was a disconnected electrical island I thought maybe there is now a market to charge transport-trailer sized batteries out of state, drive them into Texas and drain them into the grid.

tekstar··on Ask HN: What Happened to Evernote?
iOS notes!! hit the camera button from a note, scan multiple pages, turns it into a PDF
tekstar··on Ask HN: What Happened to Evernote?
Same, iOS Notes all the way.

Adding this because I didn't know about it for awhile and maybe someone reading doesn't know - iOS notes includes a pretty good document scanner with the iphone camera. Open a new note and press the camera icon, you can scan multiple pages with the camera and it turns it into a reasonable PDF.

tekstar··on Ontario's Computer: The Burroughs ICON
Yes yes yes!!! I had these in elementary school in Northern Ontario. The blog doesn't mention it but it also had multiplayer games. I remember a few..

- a horse race game where people raced horses by answering math questions

- a fishing game where your boat went across the top of the water and you had to catch fish and lobster without snagging your line

- a typing game that did not check if you typed the correct words or all the words, and would just calculate "number of words entered / time you took", so if you started a typing test and hit a letter and then escape, it would give you a ridiculous WPM score

It's wild to think that this entire system was only for such a small segment of the population, that we'd have our own computer line. What a weird time, the 1980s

tekstar··on Convoy Crackdown – power to freeze bank accounts without trial or legal recourse
I mean, aside from the noise torture they shut down a city's downtown core for 3 weeks, continually threatened, harassed, and assaulted it's residents, released multiple statements and videos calling for overthrowing and arresting elected leaders (especially women / people of colour), and the municipal police force proved itself incapable of enforcing the law and keeping Canadians safe. Not to mention the other blockades that halted more than $300mil/day in trade.

I'm done arguing with you. Bye.

> and it's something you must tolerate to have a democracy.

It's not for 21 days straight at noise levels capable of permanent hearing damage. It's really not.

tekstar··on Convoy Crackdown – power to freeze bank accounts without trial or legal recourse
Yeah the municipal government and police force were first to completely drop the ball. They didn't do their job and let our downtown become a parliament hill autonomous zone. Heck, they gave the convoy participants access to a city parking lot which was then set up as a forward operating base for their supply lines for the next 3 weeks.

If the police had managed this situation properly after the first weekend this would never have become an international issue. As a police force they basically completely failed to maintain order in the city, and that's a big part of why we required an eventual federal response to clean up the occupation that had free reign to establish itself for weeks.

I'm not a Trudeau supporter but I'm not sure what he should have done differently in this situation - he apparently had covid on the first weekend, is that what you're referring to about him fleeing? Anyways, this should have been handled by the municipal police force with adequate support from the provincial police force within the first week. I hope that the eventual federal review that comes with enacting the EA will find the root cause why our police force failed so hard.

> Maybe the scales of some are different, but calling this a "foreign-founded occupation" is disingenuous.

Weird since it was definitely foreign-funded and definitely an occupation, but okay
