Endlesss is trying to do basically that https://endlesss.fm/products/studio https://endlesss.fm/products/studio There is an iOS version available now too, which has inbuilt synths and effects but also allows external sources. That in essence means people are doing exactly that! The app is alot of fun even with little musical ability. With studio it seems they're trying to achieve your vision but in the DAW.
