One note stretch with constant time, looping and more (Variphrase-like features)

Hi, one note stretch should have an option to set it at a constant time. That is essential especially for rhythmic sounds. Being able to enter the BPM would great to as this would allow synchronizing to host tempo (which would be another most valuable feature especially for rhythmic sounds). Of. course a looping option would be great, too. Then we would be close to Variphrase possibilities.
