Chas, maybe you just own the wrong arranger keyboards

Or you are stuck on the stigma of arranger keyboards

Fact is the arranger keyboard is a tool with different features for different types of players..
My "instrument" choice is the Roland G70 for many reasons... I will try to explain why.
First the quality of the sounds equal the dedicated instruments you mentioned or own..
The piano is as good as they get,,, I have decent Rhodes . . and a decent drawbar organ.. Thus the G70 replacing all those instruments..
I do not rely on "styles", yet the G70 is perfect for my playing interest..
I can split and layer my sounds as I want... and easily saved..
I have what many consider the best key feel.. and 76 notes to play on..
What ever I would need a "workstation" for... I can use the G70 .. primarily the sequencer and effects..
I can mute enough of my styles to give me a better foundation for a project..
The G70 makes a great drum machine..
A very nice mic input with effects and harmonizer .. if and when I want one..
All from one instrument.... this is why I like and use arrangers... not for auto play.. but all my needs..
Yes I do like and use SMF play... when I want... actually prefer SMF over style.. But I don't have to rely on it..
I have a radio in my car, but
I don't have to listen to "rap".... I can listen to oldies instead... You get my point..
Just because they are called arrangers doesn't mean you can't use them as go to instruments..
