I don't post very often, but I just had to show you this one!
Peter Baartmans is demoing in a music store somewhere in the US, sitting on a crummy chair with the Tyros sitting on a crummy stand, but the music is still really, really great. Peter never seems to have an off day and always shows great professional skills. This could easily be a terrible demo, considering the way it is recorded. But to me this is yet an other example that the Tyros 4 still sounds terrific even in a non factory impromptu demo, using only the camera microphone.
Peter also seems to explain the basic workings of an arranger keyboard to the store employees
