doggieshaman you mention
"protools, nuff said. Haha, get the mbox mini thing it's the best"
if thats what you meant by HD its actually the LE. yea.
Anyway i guess your from NTU right? can i know which course are you taking? Have you heard of a lecturer name Per Magnus? hahas
The digidesign HD system is very very costly and yes it only uses digidesign stuffs. You could still use outboard gears but you still have to go through digidesign stuffs. hahas guess thats a con for PT users.
Home users definately can look into Pro-Tools if they want because its sort of like the industry standards, but right now in our age theres many other DAW that works the same way as Pro-Tools does.
Most DAW works the same way, its just that you had to find one that suits to your liking. Pro-Tools is great for its audio application as everything is flexible the key commands makes workflow really alot easier and fast.
Then again i would turn to Logic,Sonar,or even Cubase for automation as yes its alot more flexible than Pro-Tools.
Give and take, any DAW would work for you if you know how to use it well
