Thanks Andy, Lynn, Daryl, Optimus and Kenny for listening. I didn't feel like it was really finished yet so that's why i left 'demo' in the title. In particular, I feel like the vocals after the 3 minute mark may need re-work, and in general the EQ is still a work in process.
Dan and Groove, thank you very much for the constructive feedback. Very valuable. I'll do what you both suggested -- although I have never gotten the hang of ducking, so I might just ride the levels a bit and pursue the panning. I have struggled with the piano sound quite a bit so I've kind of lost perspective on it. I'll try again.
The drums are a mix of many different loop libraries that I've lost track of (I'm not in front of the DAW right now). 'Cinematic percussion' loops in some parts. The bridge drums are the bundled Session Drummer with Sonar and the MIDI pattern from the 'progressive' MIDI folder included with the software. The bass is DImension Pro, a chorused bass patch I believe.
The vox are three main sources: my own, a choir patch from DIM Pro and a new synth from Output called 'Exhale' -- it is really nice, providing a swelling Beach Boy choir sound in parts. On my own vocals, I process them heavily including some Mvocoder in spots. I do the reverse reverb effect quite a bit, where I flip the vocal, put a big echo on it and flip it back.
Thanks again for listening and the feedback. I'll post up a polished version as soon as I can.
