I sometimes EQ them, (multiband) compress them a bit or layer them with other samples.
And all the basic editing like cutting silence from the start / end.
But with the newer EQ’s, base/width filter and master compressor on the DT I mostly do this on the device itself now and resample. Much more fun 
(And with the latest DT OS 1.30B there is no more distortion with the parametric EQ’s: Digitakt 1.30 : Bug reports - #191 by maerteijn)
