Spring cleaning: free up space by deleting duplicate plug-ins

It turns out you don’t need VST2 and AU and AAX and CLAP versions of the same plug-in. Here’s a free, fast command-line tool that gets rid of them in a hurry, with options for particular configurations, on macOS.

Ardour 9.2, free and open DAW, grants user wishes — Region FX, anyone?

If you haven’t tried Ardour in a while — or if you’re new to the idea that a DAW could be free and open source — you might be surprised. Major updates and a lot of listening to users means you don’t have to sacrifice features like clip recording and editing (including looping), piano roll windows, and more. Plus you get things a lot of tools can’t do, like region effects. Ardour is worth downloading on macOS, Windows, or Linux — any of them.
