Hi there......I ve been using NWC for many years now and im really a pro when it comes to composing and notation but im afraid im not really that good when it comes to sounds......i have a 4 year old computer pentium 4 with windows xp and an on board soundcard.....when i download midi they sound fine but when i create them they sound awful..my soundcard has midi mapper using microsoft GS wavetable......i was recommended the creative platinum champion series for better realistic sounds...card slot is PCI...do you think this will work? Thanking you in advance
