I want to buy a softsynth for a laptop computer, to replace the bad default softsynth that comes with Windows. I have been very satisfied in the past with Yamaha XG, but it seems to be unavailable now. I compose classical music using Mozart software, which enables me to hear part or all of the composition without exiting the program -- but I need a softsynth that will produce realisitic imitations of acoustic instruments. Can you advise me? thanks for your attention.
