Does this still work?

I just bought a new THR amp and I want to practice with this app. This app seems to not be working with iOS 14 or maybe I am not using it correctly as there isn’t any instruction. Please update the app. I think it would be very useful if it works.

Why would you release this software with all these bugs and things that need to be fixed

You need to have every parameter adjustable and be able to be edited on this system itself that would be VMRTHR1011 or the wireless models either or you should be able to just having at least more than one to how about three how about four affects at the same time that something that shouldn’t really be that difficult this is Yamaha correct overall not too impressed you guys are leaders you make great guitars and instruments fix this

Love it

Awesome little app for learning new songs on guitar. Really cool how you can slow down the song but not change the pitch. Also, I absolutely love how it lets you isolate the guitar in a track to really hear what’s going on. Just needs some instructions!
