It was Keyzone Classic (https://www.producerspot.com/download-k ... -vst-piano), which I was using in a project because you can detune it. I wanted my piano to stay downtuned but it kept resetting to the default whenever I loaded it. All the other settings seem to save fine, however.

Alright, after doing some testing, I've figured out that the issue was with a particular VST that wasn't saving a specific value (The main one I wanted to adjust). All the other settings seem to save properly. Thank you!

I'm on windows ten, not sure what you mean by subtype (It's just standard windows 10 on version 21H1, and LMMS is 1.2.2).

Whenever I load a preset, it loads completely blank. I've tried using the larger save preset button at the top of the instrument window as well as the smaller one built into VeSTige. I'm on 1.2.2
