I have a Roland Fantom X7. I think the output level is unusually low. The other day I had that and an Alesis QS6.1 plugged into the same mixer, and the Alesis -- not exactly known for having a hot output -- was much louder. Everyone raves about the Fantom line, and a friend of mine says his is very loud. I must be doing something stupid, but I've checked everything I'm aware of. Anybody else have a similar problem?
