First open up your Vital synth in your DAW or standalone.
Then click on the hamburger menu icon to the right of preset name and choose “Import Bank”. (You can also use “Open external preset” if you only wanna open one preset.)
Then find and locate the .vitalbank file on your computer and click open.
Now it will import all the presets including the custom wavetables or custom sampled audio.
Then go to your preset browser by click the preset name bar and locate the new preset folder to see all the new presets.
