Scott,

I recently downloaded Reaper and have been working my way through the users' manual and doing all the examples using the "All through the night.rpp" file. Much of what you are asking is covered in that manual. Since it's possible to get a fully functional version of Reaper (and the manual) for free, it might be worth suggesting this.

In addition, I purchased a pdf version of "ReaMix - Breaking The Barriers" from the Reaper web page. This was the BEST $15 that I've ever spent. It homes in on exactly what you mention and more. I've just been reading my way through "corrective eq" which explicitly talks about the different types of parametric filter.

Working my way through these pdf files and, most importantly, practicing the suggestions given has enhanced my knowledge heaps. It's slow going because there's a lot to cover but the rewards have been brilliant.

Regards,
Noel
