I'm also a former trumpet player. Using brass fingerings, you'll be able to play as fast as you did on a trumpet. It doesn't too long to get used to the octave rollers. With the 4000s you'll be able to walk around and practice with just headphones. The 4000s also has a 3 or 4 more octave range than the USB. Merry Christmas, Ray
