Mungewell's zoom-zt2 is better fit for the modern pedals. I have built on this. You can find the A1 FX under my git
"GitHub - shooking/ZoomPedalFun: A collection of tips and tricks for Zoom B1On, B1XFour and G1XFour pedals." https://github.com/shooking/ZoomPedalFun
I have YouTube demos of a G5n with all the B1XFour FX I need plus some A1XFour.
With my software you can visualise the FX. With Tonelib or Zoom Guitar Lab it will pretend the FX don't exist. They do 🙂
My most recent video shows how to take a G1XFour, remove all the FX, load up the B1XFour then load the patches. It is in effect (every pun intended) a B1XFour except the Sysex ID says it is G1XFour. These pedals are almost interchangeable.
