There are several but I have to mention this.
I have put together a module with four meters. Two VU (LR) and two peak (LR).
In two different versions of the same plug they behave differently. The conditions are the same. If I copy the module from the correct behaving osm to another osm and feed it with the same data ( 2*mono noise @ 0dBFS + tick + samplerate) the meters read out differently. In the first osm it reads correct and in the next the peak meter reads out prox 4-5 dB less?????
How is that even possible. It is the same module getting the same data.....
