this unit is going to have 4 sub outs in it  this is big  we can now send  different parts to a mixer so the house can mix like a band  more bass more drums ect  i suggested that too them when i met with them 2 years ago looks like they upgraded that it was only 2 now ,  i did not see any pictures about a upgraded Piano suite like the organ section   I hope they did that   dont worry guy there is a 76 key unit .
