★★★★★ Buttons are a little buggy, and sometimes are invisible, though still functional.
★★★★★ Make sure you back everything up on the cloud regularly because the save all data option doesn't work and it doesn't give you an option to do it on cloud.
★★★★★ You can't scroll on the chain layout and the edit doesn't work.

★★★★★ BOSS should really put some money into a good application design team.
★★★★★ But until then, the Bluetooth module is a waste of money, and the app is pointless.
★★★★★ Save your money and do not buy the Bluetooth adapter.
4 of the 1 and 2 star reviews.
★★★★★ In order to upload the latest version to the amp, you have to connect a computer first, download files then upload them and all that jazz.
4 of the 1 and 2 star reviews.
★★★★★ I just don't understand why we can't add landscape support to this app.
★★★★★ Most iPad cases don't even support vertical standing.
★★★★★ I like the amp and the whole concept of tone studio but the app doesn't really support the concept very well.
2 of the 1 and 2 star reviews.
★★★★★ Forces a login on EVERY download of amp preset.
★★★★★ Why do I have to sign into my Roland account multiple times while the app is still open?
2 of the 1 and 2 star reviews.
★★★★★ Really strange that they should get it so wrong.
★★★★★ On to gen 3 and they still can't make a decent app even the tone studio disconnects from the amp on the PC. Total garbage everything goin back

★★★★★ This app will probably be great someday, but for now it is missing some pretty necessary features
Nothing stands out.

★★★★★ I don't know why there's so much hate, I understand it's frustrating having to buy a piece of equipment on top of the amp I found mine used on reverb for much cheaper. But, the app works fine although some UI with the…
★★★★★ I felt compelled to write a decent review after all the bad has come out. Now that it works with tone exchange, this app does it all and makes buying the BT module worth it.
★★★★★ I wanted a way to do deep editing off the katanas patches and this is it! Greatly enhances the usability of the Katana!

★★★★★ Adding landscape mode for the iPad would make it more user friendly to keep app open while using the amp.
★★★★★ But for a $60 plus shipping expenses it should have a much better interface and offer a more user friendly experience.

Und leider völlig unzureichende Beschreibung, wie das funktionieren soll
Barely wants to connect. Needs updating.
The app works as advertised. I’ve have no issues connecting to my iPhone or iPad. Adding landscape mode for the iPad would make it more user friendly to keep app open while using the amp.
I have a gen 3 100w and when it scans for devices all it shows is a black screen it does not connect at all
When I download a preset from tone exchange it takes 30 to 60 seconds for it to actually load on the amp. Also, the LEDs on the app go out of sync with the LEDs on the amp.
