yes, you can import longer samples to the Digitakt using the Elektron Transfer app… easy peasy. It’s more difficult to use for free-running samples, as you’re tied to the clock / bpm… i was using mostly 30-second to 75-second samples for field recordings, background activity, etc.
you can get around the loop-based rigidity using the logic conditions - there’s an A:B function, for example, where you can set an event to trigger once, every Nth pass of the 64-step cycle (combined with a slow bpm), so the sample won’t choke itself out. Like, I could set it so that a sample would only trigger once, every eight cycles, on the eighth time around (as opposed to the “first” or fourth pass, or the 7th pass etc.) - it takes a bit of forethought, and I found that you can’t really use samples over ~2 minutes, unless you don’t mind the sample choking itself out and starting over.
the Digitakt is my first Elektron experience. it takes just a couple weeks to get your head around the way it works, and it’s not always super immediate, but it’s a great little machine with a lot of potential for shaping, transforming, and arranging sounds.
