If you copy Spectre VST3 (macos arm) from one track to another, the preset will be lost. If you store the preset to A in the source, and then copy it to destination, the preset still is lost, but you can restore by pressing button A (working workaround).
Question is, why does it not properly copy the preset, too? I’ve seen this with other VST3s, too, but I don’t remember the names. Seems to be a bug. Also restoring preset data while loading a song works just normally.
