Great potential

If they fix a few bugs it would be great. App just stops mid way through songs making it frustrating to use. Also every time you use it you have to reload song which also seems sub optimal. Program should resume from last session. Also frustrating.

Excellent functionality but...

A previous reviewer mentioned something about only one channel. I can't attest to that. What I have seen so far is an excellent interface, the ability to change pace and pitch, and create a loop to practice a section of a song. The functions are straight forward and easy to manage.

All this for free is fantastic, however, I would like the ability to save the loops I've created. As it stands, I have to keep the current song in the app, otherwise, I lose my loop and have to find the song again if I exit to the main page.

Other than that one gripe, this is a fantastic program.

Neat but could be even better.

It delivers what they said it would. Easy design and clear however I would like to see an option to upload the final edit to another app like Dropbox or soundcloud so we can share our mixes. Other than that, it's great.
