Question 1

What are some of the differences between standard Protools software and Protools HD Software ?

Answer 1

Software:

• Total voiced tracks (128 mono/stereo)
• Total allowed tracks(128)
• Video Tracks (1)
• I/O (32)

Without HD Hardware:

• Total voiced tracks 256
• Total allowed tracks 764
• Video Tracks (32)
• I/O(32)

Native hardware HD
- 64 I/O
