Steinberg: Cubase Studio 4

This lighter version of Cubase 4 has all of the main features you need, including infinite audio and MIDI tracks, the new VST3 instruments and effects, and real time pitch shifting and time stretching. Your music and recordings can be edited and mastered to sound exactly how you want them, in full 32-bit audio. Capable of not only music production, with this package you can also edit the notation and print off a score. The only thing missing is surround sound mixing, which is built into Cubase 4. Comes with a USB key to avoid piracy, and is suitable for Windows XP based systems, and Mac OSX (10.4 and above only)
