hi dan; Sorry for my late reply, today, i make a check on my computer and the sibelius web site to see if i have anything wrong. on the site, they said: Minimum requirements for Sibelius 5 alone: Windows XP SP2 32-bit or Windows Vista 32-bit, 512MB+ RAM, 350MB hard disk space, DVD-ROM drive And my computer is: Microsoft Windows XP Professional Version 2002 Service Pack 3 Computer: Intel(R) Pentium(R) 4 CPU 2.40GHz 2.41 GHz, 512 MB of RAM Ok?, but they said: Additional requirements for using Sibelius Sounds Essentials and Kontakt Player 2, especially for scores with many instruments: Pentium or Athlon 1.4 GHz (or faster), 1GB+ total physical RAM, 3.5GB total hard disk space, ASIO-compatible soundcard . You may be able to use Sibelius Sounds Essentials if your computer doesn't meet the recommended requirements, but you may find that you cannot use as many sounds simultaneously. The problem isn't on the sound at all, so, what do u think?
