I think it would be cool if the game had MIDI device support so that you could play in game instruments with something other than your computer keyboard. Whilst piano is obvious of how to map the keys, for something like the drums, it would be awesome if you were also able to remap the keys.
I don’t know how easy it is to implement MIDI data to a game, or if it’s even possible at all, but if it could be done it would allow for a unique creative expression to the game and breathe new life into the instruments, giving a fresh option over the often finnicky playability of a computer keyboard.
It’s far from perfect because of the black keys requiring shift to be held, meaning lots of white + black keys together sometimes slip up and it shifts up the white keys. Having good FPS seems to help but other than that it’s very capable of playing many things.
It’ll be amazing when we do get full MIDI support
