The music I play is UK Hardcore/Hardstyle/Gabber which has a lot of distorted sounding bass. In version 2.11.1, you developers removed the ECO mode under the Transport>Keylock>Quality section, and forced it to run on HIQ mode all the time. HIQ sounds great when you slow down a track from it's base BPM, but it sounds horrendous when you speed up a track from it's base BPM. The distorted bass kicks sound muddy and lack any punch/crunch. The ECO mode actually fixed this problem. (If you want, I can provide audio examples of it). This problem even persists in current Traktor Pro 3 with your new Elastique 3 engine. I would like to see you guys bring back the ECO mode, and give us control over their time-stretch quality settings. I also would like for you to implement a dynamic hybrid quality mode as well. For example... 1.) If you slow down a track from it's base BPM, then the time-stretch engine will go into HIQ mode. 2.) If you speed up the track from it's base BPM, then the time-stretch engine will go into ECO mode. I think this hybrid mode would sound a lot better then the current implementation you guys have going right now.
