midi
What you have to do is buy something called A midi coverter.. Its midi in and midi out which go into your midi keyboard and then usb for connection to your computer. You can find an inexpensive one for about 40 or 50 bucks..
FL 7 is pretty good a couple new features and it comes with deckadance which is a mixing program..overall its pretty good but I think every1 is still holding on tight to the older but good FL versions....peace
