So the game I'm looking for seems a lot like XPilot but I'm quite sure that's not it.

The game was these triangle style ships you'd control and you'd shoot projectiles out out of them.

It was different to XPilot because I think the triangles were solid coloured and more even length on all sides, they could've also been shaped like the other ship in image 2.

The terrain was also solid and textured, could've also been destructible with the projectiles. It was somewhat dark and space themed even with the terrain being somewhat earth like.

The most certain thing I remember if that this game had MIDI music, I can remember putting it on other devices that could play MIDI.

The game also had multiplayer on one computer, I remember playing it with my friends.

Sounds like a cave-flyer - a niche genre release that is easily categorized but not easily distinguished.

I dislike not having a specific suggestion for you, but these titles tend to look sufficiently alike that I suggest you examine that list yourself. Tell me if you don't find it there and I'll start compiling a list of such titles which aren't on Mobygames yet.

Well damn there's a lot of similar games.
Gravity Force 2 and TurboRaketti look the most similar but I can recall there being MIDI music for sure

Wings, Wings 2, AUTS, A2 - The Ultimate Sequel to AUTS, The Ultimate Cave Flier, Tunnels of The Underworld, Rocket Chase, TurboRaketti, Assault Wing, Attack, ...

There're lots of this type of Finnish games (judging by your username you might be Finnish).

Wings 2 kinda looks similar but not quite the same.
