I'm finally supposed to be able to pick up my new Toaster system Thursday afternoon and I'll be spending the next who-knows-how-long figuring out what I'm doing and where I'm going with it. But I'm already wondering what software I'm going to soon discover that I MUST have. Beyond the Toaster software and all the other basic stuff that comes with an intitial setup, what should I be looking to buy? I know that I'm buying some sort of "utilities pack" with my system, but I'm more interested in the software that I'll need to amaze my friends and clients. What are the things you would recommend as the first purchases beyond the basics? What are the things you've found are absolutely essential that you wish you'd found earlier? In case it matters, I will have a Toaster 4000 with Amiga 4000, AmiLink machine control, 3/4 SP decks, TBC IV (that name doesn't sound exactly right, but I can't remember for sure) and a Cooper audio mixer. Also, I should probably tell you that the equipment will be used for TV commercials and short political pieces rather than for heavy animation. I'll appreciate any input you have. Thanks. David
