Groove and timestreching
I'm quite confusing about how can I apply time stretch to a groove, I see the official documentation and it says that you have to activate using @timestretch 1, and ten there are other attributes related like mode, quality and formant that you can use. It doesn't says that are mandatory to work, but I put them anyways. Still doesn't work.. I don't know what is happening.
If you look at the groove~ help, in particular the timestretch tab you'll see that with timestretch on pitch and playback are decoupled, so if you change the sig~ to something different from 1. ( try 0.5) you will hear the time stretch without changing pitch
