True, every single word you said Diki.
I would prefer a 76 key keyboard, but there are not too many 76 keys arrangers out there, and the ones that you can find it's either cheap, or very expensive. There is no 76 key portable arrangers in between, I don't understand why? How can people get by on 5 octaves? I mean I used do it myself back in the late 90's, with an old Roland E-68 (it had 61 keys), but once you get used to a 76, you wouldn't want to go back to a 61.
But what are my options? I'll probably stick with the BK-9, although it would be nice to try something new.
Let me ask you this Diki, what will be your next arranger in the future?
