I encountered another issue : duplicating a frozen track ignores the FX effects in the duplicated track and shows them darker as if its "frozen" although the "freeze" button is not highlighted.
how to reproduce:
in the project file "freezing_track" freeze the TTS-1 instrument track , as seen in project file "frozen_track", which shows the track "frozen".
When duplicating the frozen TTS-1 track, the FX effects color stays darker and FX effects are not applied on the duplicated one. clicking on it and changing settings on them visually works, but to no audio effect...
Adding a new FX effect does the same. No "normal" effects FX color and no effect at all...
See "duplicated_frozen_track" project file.
Also a bit weird is, that when I press "freeze" in the project file "freezing_track", then also the empty MIDI track
gets the "frozen" symbol, although its not related; maybe this is desired?!
