BassDaddy, that's one of the pages I used as a resource, and somehow I missed the double keyboard on the 'tron in that first pic. I think you could be right about some organ sound underneath the strings, as well. The patch I created with strings & brass is pretty close, but I will still play around with it some more. It has been an insanely busy week, hence my late reply, and I haven't touched the project since my last post.
I still need to jump over & give Bapu's tunes a listen and participate in some other threads, which hopefully will happen yet this week. This whole responsible husband/father/homeowner thing apparently takes up more time than one might imagine, lol. Thanks again to everyone for the help & tips & conversation!
