I want to be able to sample something and manipulate that sound and make music out of that.Those are both sample players, not samplers.
If you want a free sample player, try Soundplant. You pay if you use it for commercial purposes only. Works on old computers (older versions are also available), you can get an old laptop cheap. Samples are triggered with keyboard keys.
Depends on what you need.
