Hey Herb, I really enjoyed your post. I was searching for something else when I came upon it. I was unfamiliar with the comb filter concept. Here's my thing. I'm a woodwindist. I've been doing quite a bit of pseudo horn section, using a combination of my tenor, alto, flute, but also with the TC Helicon harmonizer. I like using that because it generates some pretty complex harmonies and if they're low enough in the mix they can sound fairly convincing. Since I'm not particularly schooled in arranging, sometimes I'll use that inspiration to re-record on horn, what's been suggested. I'd love to have access to a trumpet player, heck a bone player too. Currently, I don't. What results is a reedy, buzzy sound with just too much saxophone quality going on. I've tried techniques similar to what you described with passible results. I'm interested in a really good synthesized trumpet, good enough at least in a block of horns to sound convincing. Grateful for any additional comments you might make. Thanks!

Best, Warren
