@PhoenixSoul a lot of my game's ost are MIDI's i got off vgmusic (I hate that MIDI's are a meme ngl, I've heard some BEAUTIFUL ones) to give it that old-school rpg vibe, mostly from chrono trigger and zelda 

Ah, yeah, I hear that; I've got a mix of vibes as far as the entire OST goes, but definitely going for modern/slightly futuristic all-in-all.
Ya wanna hear about retro vibes though; Grabbag (DN3D) is also part of the game, as is Duke himself.

@kurin Problem with MIDI files is they contain no instrument data. A lot of them can sound fantastic when played with the right device/soundfont, but really off when played with others. Not as much of a problem as it used to be back in the day though I admit, since I think midi standards have settled down a lot.

Still, if I want to listen to music from chrono trigger and zelda I would go with the original music. But since RPG Maker can't emulate/play .SPC files, recordings in the .ogg format will have to do. I mean, why not? File size isn't a big concern anymore. Midis can be charming in their own way, but I still would still rather record the exact sound I want.

Sidenote: All of the music I made for my game was made using OpenMPT which is a very advanced tracker. Trackers are a lot like midi, but include samples to use as instruments .It is basically a modern decedent of software used to make music for the old Commodore Amiga line of computers. It also supports emulation of the OPL sound chip used in the Adlib/Soundblaster PC sound cards (and related to, but not the same as, the soundchip used in the Sega Genesis).

I myself tend to use a lot of OPL stuff (though usually indirectly by recording OPL instruments as samples), SNES samples (mostly from Seiken Densetsu 3/Trials of Mana), and simple waveforms (such as square waves and signwaves) so I think it can sound appropriately 'old-school' anyway. In fact OpentMPT seems really popular with a ton of chiptune artists. Plus since I am rendering it all to an .ogg file for RPG Maker anyway, I can add some special plugins and effects on top why not?

Just saying a lot of giving things that old school vibe is really about what instruments/samples you use.
