Yeah I would love to share what I used!
Every non percussion and non vocaloid instrument was done with the VST Pigments which if you don't know what that is it is just a synth VST with a ton of presets that you can alter however you want. All the presets also come categorized into sections like Bass, Keys, Lead, Strings, ETC. A lot of the presets have terrible names that don't pertain to the sound at all so the names of the ones i used are not very descriptive.
the bassline instrument was in the Lead section and is called "Mighty Mjolnir" and I had edited it to be more punchy and bouncy.
The long chords were in the Keys section and they are called "Galactic Voices"
The weird noise that plays every other section (idk how to describe it) is also found in the lead section and its name is funnily "That's Nasty" so I thought it fit gloo rather well. I also made it echo and the echo would alternate panning left and right.
The percussion comes from both the free FL studio "Grv snareclap 09" as well as the Mother 3 sound font "cabasa and kick 3" which is a fantastic sound font because of the huge variety of instruments and percussive options it has.
Then of course the Vocaloid 6 vocals which uses the voice "sakura" in the style "moonlight" who takes breaths "sometimes"
those are all the instruments I used and most of them have heavy reverb since I wanted the song to be really echoey.
That's basically it so I hope that helps!
