I'm having a problem saving and restoring some filter parameters in SampleTank 4.
For example, if I change the filter Driver parameter in the "Amped Synth" preset, it is not restored to the modified value when reopening the project after saving it.
A similar problem occurs with the Freq, Res and Driver parameters in the "Electronic Pop Kit 2 Stage" preset, for example.
Example steps to reproduce:
1) Insert an instance of SampleTank 4 on a track in Bitwig Studio.
2) Load the Amped Synth preset.
3) Change the filter Drive parameter.
4) Save and close the Bitwig project.
5) Reopen the Bitwig project.
The Drive parameter is not restored to the value it was set to before saving the project.
I tried a similar test in Reaper and encountered the same problem.
