Dave & Don,

Thanks for taking the time to reply and helping a fellow musician. Both answers make sense and I'm sure now that I have an understanding of what the function(s) of the noise gate and compressor do.

I've owned the psr9000 for about a year, but have stayed away from the harmonizer since I have been doing mostly 3 & 4 piece band work. I have done some soloing, but the band work has keep me quite busy. I thought that since we usually have 2 or 3 vocalist (including myself) in the group that I just laid out the harmonies and we sang live. About 2 weeks ago I heard an excellent 4 piece (50's and 60' rock)group and all players had excellent voices, but they used a harmonizer on nearly every backup, along with their own voices. Talk about impressive, I was amazed. Since then I have decided to incorporate the harmonizer into our band situation. Have either of you of gentlemen heard groups using harmonizers to fatten their vocals?

PS how can I find out what the factory settings are on the noise gate and compressor sections. I've been changing them and I would like to start from square one. Thanks again for all of your help.
