Got this great app yesterday having heard many accolades for it on this forum. Nothing else gets a track slower (varispeed on Logic is like a joke compared to this) and as clear as this. I just luv it. Already figured out a scalding lick with it. You can name preset locations on the track and do looping.
For a while I was using VLC with the slow playback but this went even slower. If you have to figure out some hard stuff or just want to make play along easier I highly recommend it.
It's worth the $54 for what it can do. I'm not affiliated with the company whatsoever; just wanna share this experience with my GJ brothers and sisters
