* Track counts decrease with higher sample rates.** Requires a supported hardware audio interface to monitor in surround.Easily exchange sessions with Pro Tools|HD usersWhether you’re collaborating with others or taking studio projects home with you, you can easily transfer sessions back and forth—even surround sound projects—and edit and mix sessions, regardless of the Pro Tools platform they were created on, through improved session interchange.More than double your tracksTackle large music productions and have the capacity to wrangle together the dozens of dialog bits, sound elements, effects, music, and video that go into a film or video project by expanding your track counts. Get up to 256 simultaneous audio playback tracks (up from 96), 768 total audio tracks (up from 256), 128 instrument tracks (up from 64), and 64 video tracks (up from one), enabling you to take on the most complex projects.Get highly responsive recording and playback performanceWhether your session is housed on a local hard drive, a RAID system, or network-attached storage (NAS), you’ll get better recording and playback performance than ever—even in sessions with an extremely high number of tracks. With the extended disk cache, you can have Pro Tools load your entire session into RAM to boost storage performance, system responsiveness, and reliability.Mix more easily with VCA groupsFor complex sessions with lots of automation, create VCA groups to get another layer of gain control over groups that already have automation. And, unlike with region groups, you’ll also be able to solo and mute channels within a VCA group independently—without affecting the other tracks—enabling you to work faster and more easily with grouped items.Mix in 7.1 surroundAdd movement to your mixes beyond the standard stereo field—in up to 7.1 surround sound. You can monitor surround mixes directly through the outputs of your preferred audio interface, or use the Down Mixer plug-in included in Pro Tools 10 software to monitor surround sound in stereo.Expand your post capabilitiesWork with sound for picture even easier with expanded audio editing, video editing, and automation tools. If you’re familiar with the advanced post-production features in Pro Tools HD software, these added features and tools provide a seamless transition between Pro Tools|HD and Pro Tools 10 systems.
