To my ear, I have noticed that as nice as my 770 sounds at home, on stage in a band it seems like there is a thin quality to many sounds, like piano, clav, many organs, horns. If I listen to korgs and rolands, there seems to be a totally different character to them, seemingly more of a midrange thump to them. Is there anyone out there that agrees with me, and if so, have any suggestions on how to use equalization, and perhaps compression to get better results? Or perhaps point me to any good resources on the web? I know so little about compression and equalization that trying to achieve results without guidance I am like a monkey on a typewriter trying to write a book
