Martin,
Thanks very much for your generous comments! As to your question about the sound, I do all my arrangements in Band in a Box. Then export each instrument as a wav file. Then I import all the files into Logic on my Mac, where I record all the vocals (and any other instrumentation), and do all the mixing.
When I am generating the wav files in BIAB, I pan everything center, remove all reverb, (usually) set all the tone settings to 0, and set the volume on every instrument to 111 (because I'm too lazy to type 110!). Then I do any eq, and effects, etc., all in Logic.
I'm sure everyone here has his/her own method of accomplishing what I just described. But you asked...

Thanks again!
Steve
