This is not replacing the Biab software.
This is for LIVE Use, it has to be easy and simple for any musician that's not familiar with Biab to use without the steep learning curve of the million and 1 functions and features of the software.
Have a look at the first post and check out the DigiTech Trio it won best new product @ NAMM, see what it's powered by.
Your bass player and drummer don't show up at the gig because the drummer ran off with the bass player's wife, what do you do ?
You have the SGU's of your songs, mute all tracks except bass and drums !
It even has a conductor pedal, Bluetooth, USB and HDMI ports.
It will Bluetooth to your tablet or phone to display the chord chart.
Actually mute the bass track as another bass player just showed up, he doesn't know the songs but he is following the chord chart on his phone bluetoothed to the Band in a Hardware Box.

The old bass player had enough of the live scene so he buys Biab software version to create his own songs adding VST's to them and going deep into all the menus to do all sorts of things.

Now over to Biab software, lets get that sorted out and improved.
