I'll just duplicate a post I put up at Roland-Arranger.com, to save you all surfing around... I'm hoping that I get egg all over my face when how wrong I am is pointed out to me, but I've read the manual and can't find it...
I've only taken a cursory look at this software, but unless I have missed it, I feel that Roland have missed a perfect opportunity with this iPad app...
Let me explain. It appears that the screens are set up to DUPLICATE, to a large part, the front panel of the BK device. But I see no access to most of the 'hidden' functions. Yes, you can now quickly change the Chord Recognition Type parameter, but that seems to be most of it. Personally, if I am working with this app and a BK, why do I need duplicates of buttons I already HAVE? My hands are playing the arranger, all the primary functions are right there...
But what about all the important functions buried away in sub-menus? Stuff like Fill/Rit's, 1/2 Bar Fill-In's, Reset Bar, Arranger Hold's and the like? Once upon a time, ALL of these things would have got a front panel button. But to save costs, they gradually got buried away in sub-menus, practically useless - with the exception of the BK-7m which has an FC-7 input (mind you, 7 buttons is not enough for style control AND the reappearance of these buttons).
I honestly fail to see the NEED for the arranger controls to be duplicated, but I do see a need to bring these once front panel commands back out to a place where you could actually USE THEM, live.
Now, don't get me wrong... the ability to call up and organize Performances and Styles is handy, no doubt. But I feel that an awful lot of effort has gone into duplicating functions in the app that the buttons on the keyboard are right there for you. And very little to extending the live usefulness of the app.
The good news is, if Roland owners get a hold of Roland and ASK for a screen in the app to do this, perhaps an update could address most of this. But if you don't ask, you don't get...
