allrics on Question about EZ Keys

Hello. I am new to this forum and EZ Keys. Before I give my over rating of this product I have a couple of questions.
I purchased the Bundle that comes with 2 Electric Pianos and a Grand and UpRight Piano.
In my EZ Keys Midi Library it contains:
Basic Chords, Pop/Rock, SoulRNB, Country, Gospel, Jazz, Latin, Blues, Boogie, Funk and Fx and Endings.
Then you can purchase those specific Midi Packs for $29 each.
Do the Midi Packs come with MORE Libraries then what's included in what I mentioned above? If so, where can I find what exactly do these extra charge packs come with? Thank you.
