The TONIC 2 Black Friday deal takes 33% off the zplane key and scale detector, bringing it to $26 until Nov 6, 2026.
TONIC 2 is a music theory analysis plugin. It works out the key and scale of an audio source or MIDI, then suggests notes and chords that fit.
It installs as AU, VST3 and AAX on Windows and Mac.
Put it on an audio track and press play in your DAW. TONIC 2 offers three candidate keys and scales, each with a percentage probability.
You can also drop an audio file straight into the plugin for offline analysis. MIDI tracks work too.
That covers loops, remixes, samples, recordings and rough song ideas.
Choose any of the three suggestions and the on-screen keys light up with the notes and chords that fit what you've already written.
You can audition those notes and chords on external sound sources. You can also drag specific chords into your DAW as MIDI clips.
Two modes shape how you play:
The maker pitches this as a way to explore new melodies and harmonies, or to learn more music theory.
The tuner readout is handy if you want to see how far a sample sits from standard pitch before you build around it.
