The Wersi Abacus, finally people have started to talk about a arranger that has been ahead of the game for some time now. The Abacus has an Intel CPU, Windows 98, CD burner etc., it's a computer actually. You can have a modem, video card, imagine having all your software in your board. It has a 61 key, and a add-on 76 key. It is a kb that you can upgrade for years and years. It is very expensive but expandability and upgrades keep you ahead of the new boards. The sounds are very life like and its' features are to many to list. The Genesis has been the new topic of conversation, but the Abacus has more and has been out for 2 years and like I said its a Windows based PC you can do what you want with it.
