Short and quick just to show an example:
1. Updated to mb_VST "First Update", using the three VST-2's LoudMax (
https://loudmax.blogspot.com/), Wider32.dll (
https://upload.disroot.org/r/jcNP90JY#r/TgK3WKfR4SQ4KIcpRwbLbt1CTI/gLwUTbT1hcfpOg=), and the Polyverse "Wider" (
https://polyversemusic.com/downloads/legacy/InfectedMushroom-WiderV1.0.zip) (the latter's VST-2 file renamed to "Polyverse-Wider32.dll" to avoid interference with the second example which has the same file name). Result was that all three show their GUI/Editor and retain their former settings when deselected/reselected.
2. Update to mb_VST "Second Update." Now, Polyverse-Wider32.dll will not retain its GUI's settings but reverts to default when it is deselected/reselected. The other two retain fine.
Granted "one lousy example" isn't a lot to cry foul about, but as Update #1 allows me to have my cake and eat it too with the few plugins I actively use, I will stick with it for now. I do not experience the "fast slider freeze" issue that Update #2 is meant to address.
