thanks Gary I dont have too much problem with weight of T4 but just used too it i guess

it just 970 has some of the guitar stuff on it that T4 doies not have I really love that on my T5

down side is I play guitar as well and for the most part the 970 has guitar / mic toggle one at a time this would require me to bring a board and i like to not bring a board for my quick set ups i use 2 powered speakers K 8 keyboard mic into keyboard sand then guitar in input of keyboard it looks like input is a single input small connector maybe i could make that work got to go see

having speakers on the unit would be a plus

t 4 has key 1 , 2 ,3 970 1 and 2 only

i think midi file will work the same as T4

got to see if tranpose works the same all important too me
