Bluetooth support is now available in KatanaMan and GT1Man, and GT1BassMan. This enables connection to the Boss device without requiring a USB connection to your phone/tablet. The connection relies on the use of a compatible MIDI/USB adapter. 

The CME WIDI Uhost product has been validated for this purpose. You can find the CME Uhost here:

The XSONIC Airstep Kat pedal has been validated for use with KatanaMan Pro and the Katana range of amps. You can find the Airstep Kat here:

EatonPlan apps are progressively implementing the ability to connect to your Boss™ Katana amp or GT effects processor using your Android device's Bluetooth connectivity, and a compatible, third party Midi/USB adapter. This guide provides details on how to set-up a Bluetooth connection.

KatanaMan Pro, GT1Man, GT1BMan and GT1000Mate allow you to control various functions from a footswitch, keyboard, keypad etc via Bluetooth. This article describes how to do this.

This guide describes how to connect your Boss Katana Amp or Effects Processor (GT-1 or GT-1000) to your Android phone or tablet in order to use the EatonPlan apps KatanaMan, GT1Man, GT1BMan, GT1000Mate etc. 

The Boss ™ Katana-100 is a great sounding amp with a myriad of effects, amp models, and overdrive/distortion (OD/DS) settings, but configuring the ones you want to use, switching between them whilst performing, and tweaking settings on the fly is a real challenge.

A new menu entry 'Options | Map Key Codes' allows you to now specify the characters/key codes you wish to use with your bluetooth device (eg footswitch), and which functions these are mapped to.

Both KatanaMan Pro and GT1Man now have the capability to view what we call 'Song Notes' from within the app.
