I have not worked on LabV a lot so far but I can comment the following when comparing with Lab4:
LABV plus:
- I prefer the overall ''black look'', more modern, but not the home page
- Like the RHS set up window
- studio window is good
- Keyb setting quick access (bottom screen) is better, specially when using 2 controllers (my old loved Yamaha KX8 piano..)
LAB4 plus
- I have a Keylab MKII and find it better integrated with lab4 then labV, especially for the direct instrument type selection 9 buttons. These are not the same in labV. Will there be a way to remap those the way we want?
- Samething actually for all the premaped knobs and sliders names / fonctions, They were a perfect match on Lab4. I wish we will eventually be able to map them the sameway. I found that pretty good to actually rely on the keyboard and not always on screen. with LabV, premaping is different. no true ADSR
That's it so far
