Out of interest, are you aware of any language, framework or environment that includes sound synthesis as well, essentially making it an all-in-one?
I do wonder if I'm asking too much, since Supercollider already exists but I'm not much a fan of using it because of how verbose it is and I'm a little bit upset it uses its own language (so I couldn't import more generic modules), but its worth asking anyway. My current plan is to use a non-livecoding module for an existing language, since the ability to change on the fly isn't important to me
