While using Splice INSTRUMENT, you may install content that you find you don't really care for. Since these are deeply sampled instruments they can take up quite a bit of drive space, and so it's important that you're able to remove content you no longer use.
To do so, go into the "Library" panel and find the pack or preset you want to delete. Click the 3 dots next to the pack or preset and then choose the "Remove" option.
You will be prompted to confirm, and notified that in order to use this content again you must redownload it.
