I am selling both the PX-130 and the PX-330 at my store. The PX330 has over 200 sounds vs the 130 which has only 14. Also, the PX330 has 180 accomp. styles or just drum beats with two variations and the 130 has none! The 330 has I think everything you asked for in your first question. It has Midi, it has USB it has an SD card slot, it even has a 16 track recordable and playback sequencer. There are stereo inputs and stereo outputs and it sells for $699! Oh, and did I forget ........88 hammer weighted keys with great feel and weighs only 25 lbs........
