Sounds ok.

That said, there probably isn't much going on in the sound world(or its rather going backwards, see dsound3d), so its probably OK that there isn't much development 2) How maintaining separate winmm drivers for midi and using openal for wasapi and dsound is any better than using separate wasapi drivers that do midi+wave. Since you're writing the code, if you're not concerned about (2) it's probably not an issue. Concerning (1) if I were writing this stuff I'd probably hedge my bets and avoid making openal an integral part of our sound design(like dsound via openal does). But again, you're writing the code, so you are the boss. And as far as I understand it using openal for dsound is one of your main goals and not an unintended side effect.
