If you aren’t so picky about the forced normalization, you can set up your sample (or pattern of samples) on one track and then resample it back into the digitakt using a fixed recording length with the gated recording feature, once it’s resampled you can use that in slice machine.
The downside to this, is that it will normalize your sample even if the original was loaded straight from transfer, and then sometimes even set to internal there will be minute noise present which can false trigger the gate recording and lead to imperfect loops. You have to be on your toes when you do it if you intend to set the gate to 0 or 1. You’ll have to try it out and see if that works for you or not.
That’s the thing right there. The best tip, the trick and the work around all in one. Sample curation isn’t for everyone, I lose motivation sometimes because of it but my hearing is too good to work with the results otherwise.
At least prepping on a computer and using transfer you don’t get hit with the forced normalize. If you’re resampling breaks or something which you’re setting up with precision, sometimes I record some of the dt metronome (as a click track) to make double sure that what I’m setting up (and what I’m ultimately putting back into the machine through transfer) will slice correctly.
