Features
A tab editor, an audio engine you assemble yourself, .gp compatibility in both directions, and print-quality output.
The editor
Keyboard-first, with undo on everything, and notation coverage wide enough that .gp files arrive with their articulations intact.
Resonance Engine
The playback path is yours to build. It is not a fixed sound set with a reverb knob on the end.
AI (MCP)
Tonograph is an MCP server. An AI client on the same Mac can read the score you have open, edit it, and look at the rendered notation to check its own work.
Export and print
Paper, PDF, and .gp for everyone you play with.
