Hey guys, Ive use reason 4 forever. Now using 6, before i could have multiple instruments on a rack and click back and forth to the ones i want to play or hear. Now when i add say a NNXT piano its there. Once i add say a thor rack for a track thats the only instrument i can play. I try to click back on my NNXt to go back to my piano but it still plays thor. How do i switch back and forth between my different instruments? Thanks!
