it depends on the way you work and on your workflow. If you like to control everything with knobs and sliders instead of using renoisecurve facilities itworth trying. But I`d say in most cases you will probably end in reediting the controller curves manually again. You may also try it for controlling everything which is remotable in renoise, but I didn´t do that yet, because I use renoise rather as a sequencer instead of a live instrument.
