Tone Ninja

An iPhone app for organizing compatible guitar patches, editing selected BOSS Katana settings through a compatible BLE MIDI bridge, and exploring optional AI-assisted tone tools.

Patch management, rig editing, and tone exploration.

Tone Ninja is in active development. Feature scope and compatibility may change as testing continues.

Patch library

Organize compatible patches, LiveSets, imported content, and saved versions in one mobile workspace.

Compatible rig editing

Connect selected BOSS Katana workflows through a compatible BLE MIDI bridge and work with supported amp, EQ, boost, effect, delay, and reverb parameters.

TSL movement

Import and export compatible TSL files so established patch workflows can move between Tone Ninja and supported tools.

Saved versions

Preserve useful variations and return to an earlier sound after experimenting with a patch.

AI-assisted exploration

Optional prompt, refinement, and related tone features are in development. They are intended to provide starting points while the player remains in control.

Platform and compatibility

Tone Ninja is currently being developed for iOS. Hardware behavior depends on the supported amplifier model, device generation, firmware, and connection path.
