The Kurzweil SP 88 is a quality instrument. It has various piano sounds and the other limited choice of basic sounds like organs, harpsichord, strings etc. The sounds can be edited and saved. The instrument is multi-timbrel. If memory serves me correct it doesn't have a sequencer. It has facility for splitting the keyboard into parts where different sounds are triggered on different sections of the keyboard. It has some cheesy drum sounds. There are the usual line outs, pedal outs, midi in/outs. The keyboard feels like a real piano. The piano is heavy. [b]UTILIZATION[/b]The one drawback of this keyboard is that it is not user friendly when accessing the deeper functions which requires the manual to figure out. It is also very heavy but it is transportable. [b]SOUNDS[/b]This digital piano sounds great! It sounds very much like a real piano. And the fidelity of the output sound is extremely good. All the output sounds sound very solid and strong with very low if any background noise. On recordings it sounds like a real piano. Not all of the piano sounds are great but there are a few great ones. [b]OVERALL OPINION[/b]I was fortunate enough to be able to borrow one of these from a friend for a while when they didnt have space for it. Eventually I had to return it to the owner. I deeply miss the it now that its gone. However I am not a true piano player. I do most of my stuff in midi in a daw. The best thing about this digital piano is that it feels and sounds like a real piano. I like to play in a beautiful romantic style using the damper pedal. With this piano I could easily get into and feel inspired by the sound. I have looked for another digital piano since losing this one but I have been looking in the to find one in budget.
