Great, but needs ability to save! Also needs iOS 8 Update.

This app was one of the reasons I recently bought an iPhone. I wanted the ability to loop a section of a song for practicing guitar. This app does that pretty well. The feature it's lacking however, is the ability to save loops. It's time consuming having to reopen a song, find the part to loop each time you want to practice. Why not just offer an option to save loops? If they did that, I'd pay $20 for this app.

Also, apparently this app isn't iOS8 ready. I hope they do this soon so I can update my phone. Anyway…thanks for the free app. I own the THR10X guitar amp as well and would recommend it to anyone looking for a good feature rich recording device and practice amp.

Just waiting

Just waiting the ios8 compatibility... It was sad to use another "not even close" app to learn 14 songs from Slayer (for the Vallyum band I was called) in the last week! So hope you fix it soon !

Doesn't work with iOS 8

This used to be a great little app for slowing down and isolating bits of songs I was trying to learn. It's major flaw was that I had to re-load the song each time I sparked up the app, which was time consuming and unnecessary. Add to that the fact there have been no updates in about 2 years and one wonders about Yamaha's commitment to the app.

But ever since I upgraded (?) to iOS 8, the app doesn't work at all. If they fix this bug, then great. If not, well, at least it was free.
