I believe that Yamaha wants you to use the compression to optimize the load on the speakers. Mastering tools help mask the subpar vocal processor in the unit. I don't mean to sound harsh, but that's the way I see it. If you use all the effects to smooth out and flatten the signal, the harmonizer works as good as it can, and you notice less of it's shortcomings.
I advise all serious singers to be stingy with compression. It can seriously alter your dynamic range, and change your performance if you're not really careful with it. In the right hands, in the right amounts ... it's a great tool, but more often than not, it detracts from a good singers performance.

In my case, since I use 2-3 harmonized voices pretty often, I like the fact that a compressor can keep the "boys" in check when I get excited. Internal kb speakers (like many of you, here) can only take so much of Uncle Dave.

Dave, at the time Donnie asked, he was still setting up the Korg. He as since moved on, or should I say backwards!

No! Don't need it!

One step backwards =
Two steps forward!
Gotta run FedEx is here Yea!!!

Compressor is always good to use if you understand what it does and how it works.

Aaaah!

I Think Dnj just went back to Yamaha. Maybe a Tyros 5?

Donny, have you got rid of your Korg Pa900?

SD7 & Pa900 are gone..Around & Round we go, where it stops?....
I know!!

Yamaha S950 is the place for me, .....
I always have to learn a lesson the HARD way!

Amazing grace, How sweet the sound
That saved a wretch like me.
I once was lost, but now am found,
Was blind, but now I see.
