The TX16Wx is simply the best option to get when looking for a highly functional, yet affordable software sampler. Of course if you don't need pro features like time stretch or pitch shift it's free even! I've thoroughly compared it with Akai's MPC software and imo it does everything related to sampling, sample mapping and editing even faster once you've adapted to its workflow. It's pure efficiency and if you make a good suggestion to further improve the workflow or functionality the creator will be really quick to adapt.
Combine this sampler with Reaper and maybe Surge and you'll have enough music production possibilities and depth for a lifetime, if you are only willing to learn your tools well.
