As of now my band is instrumental with no singer. There are 2 guitars, a bass and drums and we are pretty loud. On boost 11 I would probably mix well, but I shouldn't be pushing it this much, right? What I don't understand is if the keyboards output is weak then why is it louder on my 120watt crate guitar amp im using in my band now...and I have that at about half way volume, with my keyboard volume at one o'clock position...I guess I just dont want to spend $100 on the mixer if its not the problem...
