This genre of musical sandbox is a really satisfying and fun rabbit hole. You can even take it to production (mainly ambient music production, that is). My favorite for usage inside DAWs is Droplets, which works as a plugin but also has a web version: https://fynthesizer.github.io/Drip/
There are other plugins for this, each with its own personality. For example Bitwig's Ricochet is a totally different take on the same idea, where they managed to make it usable for more rhythmic purposes: https://www.youtube.com/watch?v=WFvIYkTGRzA
