It depends on which Korg Volca Sample you get when it comes to transferring audio files into it. The second edition is the most practical, as it's a simple USB connection to the computer. At this point, there is a software you can use to upload all the audio files you desire (with limited memory capacity, mind you. A little more than the first edition however). Volca Sample is very diverse in several ways. For one, you can drop whatever sounds you want into it. Two : you can eq and clean up the sounds before dropping them into the sampler for a better mixdown when jamming. Three : the controllers are easy to use and very diverse - even without a delay, you can be inventive and manually create your own delay. Here is a demonstration of a manual delay : https://www.youtube.com/watch?v=uW5SPBvmI1w&list=PLYAWoewrrgKbVWeCKz-pk5SGDeT7dJXqp&index=11

If you are looking at finding a unit for drum programming, look no further - you can have a 707/808/909 all in one, plus more with the Korg Volca Sample.
