There is a HUGE problem with these small key arrangers. you simply cant play as fast!!

Nothing to do with the size of the keys - its to do with mass...The same player on a Hammond B3 will be able to play far more notes over a period of a million years or so because time passes slower in the vicinity of a greater mass. So if you want to play fast Latin stuff, definatley avoid the Korg. The Audya 76 is the probably heaviest current arranger so thats the one to go for. plus...you will live longer too.

I think I just came up with my new ad campaign:

"Ketron Audya; Live Longer. Play Faster"
