Thanks Dan for your prompt answers, few more questions:
If I need to read lyrics, how this will display on the screen? Can it be scrolled? Will it cover the vArranger partially that you lose some controls? Do you have screenshots of this scenario? I'm just concern due to my 15.6" screen size.
I've got a non-touch Intel I5 laptop, so I'm thinking to get a lightweight, compact 61 key midi-controller with several sliders and buttons (ie Necktar Impact LX61). Is it better to control vArranger on touch screen or on mapped midi keyboard with sliders, pads and buttons on live situation?
Does vArranger guess SMF chords like the Rolands?
Does it memorizes intros and parts volumes on registrations?
Thank you once again.
