ableton live is pretty flexible and widely used. but i think renoise is more powerful in many ways. and it’s cheaper, runs on more platforms, and has many open-source sampling/slicing addons, on top of the built-in utilities. i think it’s more powerful than ableton just using the built-in renoise tools, let alone the community-made addons. most of my musical projects run through renoise at some point. i use it for nearly all of the MCRPs, LCRPs, disquiet juntos, and other projects that involve extensive sample manipulation. it’s also nice for quick, easy things like through-zero wave cutting and fx re-sampling. much faster than audacity, and with a UI that’s much friendlier and more powerful than audacity.
