Soundfont suggestions

[Squid Socks]

Hey,
I've been using OmniMIDI because I had some issues with my p99 midi files not playing on windows 10.
I've pretty much solved the whole problem with the help of previous forum posts I'm sure a lot of you know about; but my problem now is the "base and background"(idk how else to describe it) noise seems to be off tempo and tune.

I'm using 1mgm.sf2 and synthusr.sf2 but I've heard those two are pretty dated so maybe that's my issue?
any suggestions on newer soundfonts that sound better?
