I think I might have found a little bug in SigmaStudio.
I am using version 3.11.1.
The RMS limiter block can output, apart from the audio signal, the miniting ratio as well as a FLAG when then limiter is acting.
The help file states that the first red pin (middle pin) outputs the ratio, and the second red pin outputs the flag:
this is indeed the case, however, when you mouse over the pins the user receives the wrong information
It states that second red pin outputs the flag and the first red pin (the one in the middle) outputs the ratio.
This can be a cause of ambiguity to the user.
