The music and sound effect continue on the ride. There are a lot more sound effects (that I noticed anyway) that build a tapestry on the ride. Lots of little space noises like vortexes and shooting stars, they really make good use of doppler effect. There is music interspersed as well but it isn’t overwhelming or really noticeable (unless you are paying attention). You are passing speakers at different locations, at different distances, and different depths all building the experiences.
By the time you are to the exit the music is more modern and upbeat…not my favorite but it matches the energy of the ride by the end that is really well done.
The old sound effects (launch and worm-hole) are still there but seem a lot richer, more range to the effect and real depth (not the old flat, tinny, sounds like one speaker sounding effect).
With the new darkness of the ride, the star field, the smoothed track, the pre-show games, and now the new sound system I am more then happy with the 2009 rehab.
I think everyone is going to love this upgrade to the ride.
