I'm very happy with Renoise but it has a problem, it can't do realtime pitchshifting.

For example, consider a breakbreat which I want to trigger at different pitches sometimes. Like I keep 'Q' pressed for a 'C' pitch, but then I press 'B' for a lower pitch. In Renoise the resulting beat is not only lower pitch, but also longer/slower. I want it to be the same speed, just a different pitch. I've been doing this externally in Audacity, then keeping a couple of different pitched versions in Renoise but that's tedious.

Or consider a melodic segment snipped from a song into a sample. Say I want to play it simultaneously in its real pitch and 5 semitones higher, so it forms a sort of chord effect. Again, no easy way to do this in renoise.

Is there a DAW app that does that kind of thing? I've heard of ableton live, it has 'live' in the name so maybe it can do it?
