A patch editor and librarian for your BOSS Katana amplifier.

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).
