My studio's predominately hardware based too, but the PC is just another tool...mine even
sits nicely in my rack with all my other gear

However, like with RTAs, there are some things that a PC can do better than, (and more
often than not cheaper than), a dedicated hardware unit.
With the greatest of
respect, in 2007 i'd have thought a PC would be an essential hardware component in any
music studio. You don't have to use it as a master controller, or change your current
practices in anyway, but instead just use it as a cheap and extremely versatile FX
processor if nothing else.
I can understand not wanting to use a computer,
especially with the danger of relying on it more and more, but surely you're missing a
trick by not using one at all. As i say it's a cheap, powerful tool that you can use to
whatever end you decide...and in your position you wouldn't need a powerful machine or an
expensive soundcard to take advantage of all the free VST plugins out there!
