Playback software HELP.

Hi guys. THIS IS A LONG QUESTION- im sorry.

I am new here, and I have a ba degree in instrumental music ed. Not much to go on. But I LOVE composing music, and I have a few pieces I have just poured myself into creating. The BEST playback I have had is with musevub and musesounds on the newest musescoe 4. I have ableton live 12 standard, logic prox, and a couple midis. I also believe I have some form of kontakt 7? Im not sure. But I have discovered when converting my comps into a midi file to drag and drop them into my DAWS, they Do not Support the same playback because musesound has a unique engine. And that is the best sounding string section I have ever heard ;( does ANYONE know where I should go to find realistic sounding playback, or at least decent ones so I can tweak them? I just dont want to spend a bunch of money on something I wont use.
