Neptune RGB Elite - DELETE On the fly Macro

[Diegoev]

Simple question, the next operation is not on any of the product manuals. Ive fund how to do it in other model, but looks like is not the same procedure here.
Ive set a macro on a key of my Neptune RGB Elite In every paper and even the box, and in the product site explains this, how to Make an on the fly Macro. But is missing how do we delete an on the fly macros And now I am with a missing letter since the only thing that works there is the recorded macro.
Any help here please 😃
