When reloading the synthesizer, if the “Band Spread Flange -” filter was used in the preset, the filter type is reset to the previous one (“Band Spread Flange +”). I also noticed a change in the timbre of the sound even if “Band Spread Flange +” is selected. In general, sound changes after reloading the project with filters like “Band Spread Flange”. I am using Bitwig Studio.
The problem concerns version VST3. VST2 works correctly in this sense.
