Mpc key groups root note

Hello
Mpc live 2 - Working with key groups could you help with the following-
1- if a sample has the root note in the sample title heading will Mpc automatically put this in the root note box in sample edit???
2- Does the root note box in sample edit dictate where Mpc places note/sample on the keyboard???
3-If you was to load 128 key groups in a key group program and use 4 layers per key how would the Mpc play over 500 samples
Thanks guys

1-No, you need to assign it yourself
2-Yes, helps for keygroups
3-You mean 128 samples in a key group program? I don't believe the MPC can play over 128 samples... but might be wrong.
