Kind of - that's switching between a fast version and a slow version of the track though if that makes sense, rather than changing the global tempo, so you'll get discontinuities in the music.
You can change the global tempo with something like
Strudel was moved to codeberg for ethical reasons. Annoying to see so many people forking it back to github in order to make yet another LLM interface.
Fast growth of the project isn't our goal and definitely doesn't override our collective ethics. If someone will only send PRs via a proprietary Microsoft platform then maybe this isn't the project for them.
I've worked with groups of 8 year olds and got them performing music together in less than an hour with tidal (strudel's older sibling). It's not easier than learning to play a drum but it's not really harder either.
It's nothing like trying to teach kids an imperative programming language, it's not really in the same category as general purpose programming. It's designed for music making and you can make complex rhythms very quickly out of very simple parts.
Speaking as a member of the Strudel project in the OP, it went really well, everything migrated across (issues, PRs etc) pretty much seamlessly. We have to self-host the ci actions, but as a bonus now they run much faster.
It really is a no-brainer for any free/open source project to be hosted on a free/open source platform. It's pretty nuts that so many stay on Microsoft github who are busy IP-stripping everything via AI, even without considering all the other terrible stuff MS get up to that it's best not to support or be associated with.
Quite a few live coding platforms are making the move to codeberg too. It's a bit trickier for desktop apps like supercollider who depend on cross-platform ci builds though.
Don't see why moving from the closed source Microsoft Github to free/open source codeberg would turn away any grassroots developer. It's like two extra characters to type and live coders can usually type quite fast.
It is usually worth trying the dev version at: https://warm.strudel.cc/
although I think that's close to the live version at the moment.
