Tim first of all I am a home user not a pro musician and I've been working with computer based software for a moth. What I meant is, as a different option, you could buy a much lesser expensive keyboard like a Pa 500 or 588 if you need the whole 88 weigthed keyboard to get the style engine of Korg arrangers and spend the rest of the money to buy a computer and some software to play VSTi (virtual instruments). If you play a Vsti for the melody part alone (not as part of the style itself)it is not very complex to use and the computer is usually very stable. Computers are a whole different world to get involved with, and you may get lost at first, but you will find the best sounds ever produced and you won't need to change keyboards so often. Most active members in this forum are players who need something practical light, safe and fast so it's not convenient for them yet. Others tried software programs to make styles and compose music and tell us that it is a nightmare to use so they went back to regular arrangers. I'm recomending this to you just to play the computer sounds from your own arranger, since it is your hobby you may enjoy discovering new sounds every day.
