Hey Vadim!

Professional or not?
That¡¦s a tough one to answer..¡K
Especially nowadays , when everything is packed with features and options.
Just check out the ¡§General Arranger keyboard¡¨ forum here.
See what the guys that use arrangers talk about.
They talk about digital audio, soft synths, mixing, recording and just about anything under the sun that has to do with professional studio work.
Some guys there can give me lessons on physical modeling and FM programming.

If you feel that you¡¦ve outgrown a keyboard that you¡¦re using, it may not necessarily have to do with the fact that it¡¦s an arranger. May be you just need a new arranger board, with more features, WORKING KEYS (still broken..I take it? ƒº )
And more editing capabilities then your current board offers.
You never know.
On the other hand, if you feel that you don¡¦t need to use styles, and would rather do some intence sequencing of your own ¡V workstation might be just right for ya!
Of coarse, nothing compares to the software sequencers, but that¡¥s a different story.

And fix that key., Any board with the broken key sucks BIG time.
I knnow, I¡¦ve been there.
It¡¦s actually more annoying then a broken string on a guitar.

Later.
