Hi.
I think that it would be smart to investigate mzero’s elk herd for sample management and see if it’s a better approach for you. The ability to reorganize the +drive is a bit more flexible than transfer. Check out the dedicated topic (and davemech’s walk through video) for more info.
I believe that there are several discussions re: general sample management practices, I’ll find one that I can link you to if you’re interested in how others approach the topic. Ultimately, if your goal is performing with this hardware, there are many benefits to organizing all of your content under the umbrella of a single project, but everyone has to do what makes the most sense for them.
You can check out some of the topics PofM mentions in his post here if interested:
Also, using sample chains is an effective way to make use of space and a different way to approach kits (meaning not the standard elektron “kits”) via utilizing the grid machine, and digichain is a really nice free utility for that purpose created by Brian3kb who is a member here.
Just as general naggyness I would encourage you to frequently back up your projects using transfer, as it just may save your ass one of these days.
Hold on and I’ll add a couple of links to this post (edit: amended)
Anyways hopefully some of that is useful to you.
Good luck.
