Make use of pitched up Flexi and processing to resample and dirty up your sounds.
Load a sample in to Sampler (1st Flexi).
Arm Resampler (2nd Flexi) for recording and then trigger Sampler to play. Stop the recording. Voila! Instant sampler artifacts.
Adjust and/add processors between Sampler and Resampler. Reduce the Pitch to lessen the resampling artifacts.
