slowing down clips/tape/sounds, like the OP1
Use case example, on the OP-1, you record something at 64bpm. But you then change the tape speed to playback a bit slower, say 50bpm. You like this feel, you even want the pitch shift. In Ableton, set the project bpm to 50. Import your stem/clips whatever you want to call them. In the track parameters, enable "warp" and set the bpm to the original tempo - in our case 64. Set the warp type to repitch & ta-da you have a similar effect. The reverse should apply for speeding up!
