GPO is pretty decent. I have it in my DAW. I used to do a lot of midi composing and it was used quite a bit. Now days, I work a lot with audio so it hasn't been loaded in quite some time.

Quality wise, it's good. Price point is good too. Not to expensive. If you need something that's a step up from GM sounds and are not sure what to get, GPO is a good option.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
