Exa is essentially a customizable percussion instrument in VR. I like it quite a bit because you can swing through all the notes, which feels way better in VR than trying to pull back from a drum without a real bounce. Here's a few videos with I did trying to play like that:

Sadly EXA's development is dead, so no more updates. It's quite functional as is though, and besides its (basic) sampling and sequencing ability (you can do live looping with yourself), you can also get the MIDI out into a regular daw. 

There's also Tranzient, which is still developed and has a free demo on Steam, which I'll try out at some point.
