I load a preset and change it. Everything's fine. If I reload the saved project or the saved preset, the sound no longer sounds as expected. Does anyone have a similar problem? I use Massive X under KOMPLETE KONTROL (latest Version).
How do you save the preset exactly and how do you recall it? From your user library?
You mentioend saved project, what DAW are you using?
Do Komplete Kontrol and your DAW have full disk access? How to Enable Full Disk Access on macOS
Can you provide screenshots, or even better a small video showcasing the issue so we can see what could be wrong?
