Axe FX III - Tuner & Blocks

[rjmmusic]

Thank you. I can confirm turning on IA Link worked for the button to Engage/Bypass the block. It also worked to keep the active channel in sync via the Hold function.

Curious, what is the difference between IA Link and CC Link?

There used to be more of a difference, but IA Link keeps adding more functionality and encroaching on CC Link's features. In short, if you want to use a computer to control individual buttons on the GT using CCs, use CC Link. Otherwise, use IA Link.
