No loyalty at all. I feel there some outstanding features on all the major manufactures keyboards and if I could afford it I’d have a couple of TOTL and even MOTL keyboards. But in reality I would hate to have to figure all those operating systems- that would not be time well spent. I feel pretty comfortable with my Tyros 2 despite not 100% satisfied with the sound of the drums and styles. If I were to get a Korg, Roland or Ketron I’d probably be satisfied with the drums/styles but not so much with the RH sounds. Plus learning a new OS would be a huge PITA… I rather spend my time working on my musicianship.
