Thanks for the help All. I've gone back to university (after a few decades) and my wife just lost her job, so I've sworn an oath to not spend a penny until she's back at work. I'm looking forward to getting Simon Cann's Cakewalk synthesizer book as well as his "How to Make a Noise: Sample-Based Synthesis" book. And I'll grab the Univeral 120 collection as well.
In the meantime, I'm going to start reading the 4000+ posts that have been written to this forum since November 2005 and also dissecting the samples I do have.
Should keep me busy for a while.
