You can program the colors of the lcd’s!
Seriously though, every button is programable - times 2 - as you can have 2 functions per button. It is completely customizable - you can have as many pc buttons in any location you want - same for ia’s, or even just simple functions (page up page down etc). You can program each button to trigger and toggle or just plain trigger, you can have a single button programmed to do a sequence of things such as make a pc and switch to a new page (pages are awesome) in which all buttons are now, for instance, ia’s - such that you can hit a pc to select a rig, and instantly you have control of every parameter of the rig (joptunes taught me this trick). You can control various parameters with a mission pedal, including gain, delay feedback, delay mix etc as well as volume pitch wah etc. (I'm betting your roland can do this too, more of a kemper thing).
I have 2 LF+’s, basically both used as masters, one stage left, one stage right, and they mirror each other. Connected by a cat 5 cable.
It will accept midi data from the kemper for things like tuning, rig names etc
In the end though use what works for you - my LF's replaced 2 rim masterminds (not the gt's) which functioned very well for what they were.....the LF's are definitely fancier though!
