The Yamaha 205D Electone is a dual keyboard electric piano that also has foot pedals and a ton of different tones and effects.  It has built in drum samples and loops in all sorts of styles and has switches for changing your tone to model after all sorts of different instruments.  It also has effects like vibrato and sustain and has presets for vibes, guitar, and piano.  It has a volume pedal as wel and also has a built in speaker.  While there is a lot going on with the all of the different sections and parameters of this keyboard, after playing around with it for a little while I was able to figure out what everything does.  However, I am always finding out little quirks about this instrument the more and more that I play around with it.  The sounds that you can get across the board are pretty cheesy, but at the same time they have a pretty cool quality to them, although some are certainly better than others.  I really like the vibraphone preset that this has and also really like the different acoustic instrument simulators as blending them can get you some really cool sounds.  One of the best parts about the Yamaha 205D Electone is that it has a section of arpeggiators which adds all sorts of cool sounds to the mix and I generally like to have one of the arpeggiators going at all times.  With the arpeggitor and rhythm section (which contains options for bass as well), you can pretty much have a little one man band going with this.  While the sounds are unique and fun you can't really get serious organ or piano sounds on this keyboard so you really need to take it for what it is and that is a unque sounding keyboard!
