## What is Katana Tone Control?

Katana Tone Editor is a full-featured tone editor for the BOSS Katana MkII amplifier series, built for guitarists whose gear has outgrown official software support.

FEATURES
- Full control of Gain, EQ, Volume, and Amp Type across all amp channels
- Edit all five effects blocks — Booster, Mod, FX, Delay, and Reverb
- Browse and manage both channel banks (A and B) plus Panel mode
- Import .tsl patch files, including bulk import of entire patch libraries
- Assign imported patches to any channel and upload directly to your amp
- Real-time sync — changes made on the amp's own panel appear instantly in the app, and vice versa
- Works over direct USB or Bluetooth MIDI (including third-party MIDI-to-Bluetooth adapters)

COMPATIBILITY
Katana-50 MkII, Katana-100 MkII, Katana-100/212 MkII, Katana-Head MkII, and Katana-Artist MkII.

WHY THIS APP
Official editor software for the Katana MkII series has aged out of support on current operating systems. Katana Tone Editor was built from the ground up to give Katana MkII owners a modern, reliable way to keep editing their tone — using the amp's own standard MIDI implementation, with no proprietary driver required.
