Apps For Amps

About this app

Katana Librarian allows you to connect your phone or tablet to your BOSS Katana amplifier via USB or a Bluetooth adapter (sold separately), unlocking your amp’s full potential!

The free version of the app allows you to test your connection and load the built-in demo patches. A one-time in-app purchase is offered if you wish to unlock the full feature set, which will allow you to:

- Download patches from your amplifier.
- Modify the patch parameters; includes support for all effect types; the editor also changes in real-time as you adjust the parameters on your amp.
- Organize your patches into groups. Tag your favorite patches, or create a set list for a live performance.
- Import and export MkI, MkII, Gen3 and GO .TSL files.
- Rename and delete patches.
- Write patches to the amplifier's channels.
- Emulate the functionality of a GA-FC pedal (even on a KATANA-50 or KATANA:GO).
- Use the hotkey feature in combination with a Bluetooth MIDI or HID foot switch (e.g. https://amzn.to/3RqNcDY) for hands-free patch and effect switching.
- Access undocumented Katana features like hidden amps and multiple simultaneous effects (where available).

Ratings and reviews

This has been a life saver during gigs. It gets a bit flaky once in awhile but I suspect it's my phone/cable connection and not the app. I play in every bands that have very different needs. ** Wish list ** I would love the ability to save a set of 8 patches to a group that I can name and load them in one shot rather than one by one when I switch bands. Maybe this exists already? I would also like to have more functionality without having to be connected to my Katana.

Wow! This app has it all and is very easy to use! This provides a much easier and more portable means of accessing Tone Studio functions than lugging around a laptop. Plus it includes lots of "secret" amp models and lots of other cool stuff. The app also makes it very easy to search for and download patches from Facebook groups, websites, the cloud or just about anywhere. It worked perfectly with my Samsung Tab A Android tablet using the OTG USB adapter. I bought the full version and I love it!

Works great. No problems so far. The ease of use makes it my go to app for quick patch changes. I bought the full version and haven't regretted it. No connection issues everything is compatible, phone, app, amp... Cables are easy to find and inexpensive. Otg and USBa to USBb "printer" cables are a little outdated but still works. Cool app I would highly recommend it.

What’s new

- Add support for the KATANA:GO tuner
- Improve GO patch conversions
