Re: where are my samples in my dra...
Sorry but I don;t understand...
When you try loading the UB kit (preset) you created, does an alert window pop up to tell you that it can't find the samples?
... surely you don't want to "commit" your samples ;-)
... OK seriously. If you want your Logic project to be autonomous and be moved anywhere and keep all the samples intact then you've got to choose to Save assets.
In the Save as... dialogue window you'll see an 'Advanced' disclosure arrow.
Click on it.
From the list you can choose to save audio files and samples for EXS24 and UB to the project folder.
This can eat a lot of space, but is useful if you need to send someone your project who may not have the same samples as you or you decide to move your samples around.
btw, in your UB preset kit. Take a look in the Sample window (where you import audio files). For each voice there should be the name of the file there. You can use the name there to then locate the file and reimport it.
