Alright so the next feature request is that WatchCat uses all the settings from the preset file when processing!
I would imagine that if a user who has specifically saved a preset file that has also FM settings in it would also want to hear it exactly like that in the processed file also. Otherwise they would have saved a different preset file with no FM settings on. WatchCat should not leave anything out from the processed file compared to the preset file a user has applied!
Well, a lot of presets contain both settings for normal output and FM output. It's not that it purposely leaves anything out, it's just taking the normal output settings, which makes sense since we're processing left/right files here. In this case the difference in highs is probably mostly caused by the difference in clipping level. We'll think a bit about this though.
