And if your favorite manufacturer does not have a black pro looking keyboard, an arranger module is the perfect solution. You can use your favorite black pro looking keyboard (arranger or workstation) midied to the arranger module and you have the best of both worlds.
So the workstation players who frown on arrangers but secretively would like to use them on gigs, can do so with an arranger module.
And, it would not take but one additional minute to set-up an arranger module for the benefit of having fresh sounds and styles.
