I replaced a fully functional MixWiz. Been using that for the last 6 years and it's been solid, so the ipad remote capability and show saving functions were what sold me on the DL. I don't think it has been a mistake and without regard to what anyone else makes, the DL is the mixer I'm going to be depending upon for the next 5 years. (Maybe longer.) I'm looking forward to the improvements that Mackie is planning for Master Fader. If they ever decide to put Master Fader aside, I would hope that they would open up its development to us. (A lot of us have had some programming over many years. In my case, Pascal, PL1, Assembler, Basic Fortran, RPG)
