The GM sounds are not great and don't compare to the quality of even basic sound modules. In fact it is worse than the sounds out of the little kiddy keyboards you find at your local BestBuy. The only sounds that do sound very good are the push button presets. I really love the classical piano sound on this keyboard.

Love that it comes with midi, audio imputs and ouputs. Damper and soft imputs are great. The only thing I found that I didn't like was the imputs are made of plastic and look rather flimsy, but we'll see how they hold up. Also, I couldn't use my Yamaha sostenuto pedal I bought seperately because function is reversed on this keyboard (up is sostenuto down is release) you have to re-wire your pedal.

I own three digital pianos and non of them compares to the Privia. Most digital pianos tend to have keys that are too light, the keys also tend to fall to quickly. These digital pianos also tend to have a rather crude thump as the key hits the bottom, which becomes rather annoying and unnatural. The Casio Privia however is one of the first digital pianos where you forget that your playing a digital piano. I play acoustic pianos and have never liked digital pianos very much because they don't feel right, but the hammer action alone on this piano is amazing and is worth more than it sells for.

Although the GM sounds are no good, the hammer action on the Privia is worth more than the price you pay.

Never had to use it.

Very atractive keyboard, picked the PX-300 because of the looks, would have gotton the PX-100 but didn't like the old 70's wood look, very bad.
