hi taike
yes like you say franz lambert is so fast with his on the fly changes but it seems to me that most of the top players that use wersi are the same, just watch cauldia or mark or the late klaus on any of the clips that abucus has given us links too and they too are really quick at there changes too. to hear someone play a top of the range organ and use no backing tracks or auto rhythm and only hear them play is something of wonder. a top organist playing a top of the range organ will always sound better that a top keybord player playing a keyboard and i include the wersi keyboards too. you just cant do the same on a top of the range keybard you can on a top of the range organ unless you program everything in first and and even if you add a second keyboard and peddles the changing of set ups is so much harder with the keyboards as that what i try and do now with my 2 keyboard and its no where as easy as when i had the organ. i know the abacus is set up very like my old specta organ and that will be close to ease of use.
