Not sure if this is a suitable question to ask, but I just bought a yamaha DGX640. Everything is great. It has many voices, but I just wanted grand piano, which the unit has several. The problem is they all sound... dull, for the lack of word. I tried playing around with DSP (sound effect) and Reverb, but the result is not very satisfying.
I am hoping this is a common configuration that I can change real quick. Can sound experts help please? Or put me to the right web resource?
