welcome back! Everything should still be the overtone you know and love, in terms of usage very little has changed, except that now you need to install supercollider yourself first, but that's explained in the wiki. We no longer embed our own copy of supercollider. For the rest it's mostly just making sure that stuff that used to work or is supposed to work actually just works. So if you encounter any barriers to getting started then do let me know, I really want to get rid of all the annoying sharp edges that put people off from using overtone.

Oh, I'm sure I don't even remember how to install it offhand, so I won't notice any changes 😉

I remember having to fiddle jack. Should be fun with pipewire added to the mix</s>

So that's one of the areas where I've tried hard to make it smooth, but it'll depend on your distribution. We're in a transitional phase where pipewire can act as a jack server, but applications that use the jack API are not necessarily finding pipewire. It depends on the right shared libraries getting used. There's a wrapper script call pw-jack which sets the right LD_LIBRARY_PATH, and if we notice that you're running pipewire, and pw-jack is on the path, then scsynth will get wrapped so it "just works". But you might want to check if pw-jack is available for you or not.

on Ubuntu you need the pipewire-jack package
