Wotja: No, sorry! That may be supported later (TBD). NB: Even if you create a pak, the loops must be in 16-bit format (24-bit is not supported at this time).
Mixtikl: Yes, you can, but remember that when not in a correctly formatted Pak they will not be pitch shifted or time stretched if you change the mix root or tempo. For the content you want to use, simply copy it to the "Intermorphic Folder".
