I really would like a method where you can change the dynamics of the sample like in FL Studio. For example, making the waveform play faster (Shorter or lengthen it) without actually putting on a track and time stretching it. It would be efficient an official tool for sample xt/ impact. This is esp useful for beats.
Other possible editing features:
1. Making a slicer. Slice up the sample
2. Being able to change the Sample shift like in Presence.
