What's in the dojo

Ear Training

Intervals, chords & harmonic recognition by ear.

Identify triads, sevenths & extensions by sound.

Metronome

Precision timing. No drift. Subdivision control.

Rhythm Gate

Hear a pattern. Tap it back. Master groove.

Scale Runner

Play target scales on MIDI — speed and accuracy.

MIDI Games

Chord Attack, Velocity Strike & more. Connect any keyboard.

Hear it, play it back. MIDI drills close the loop — identify the interval, then voice it on your keyboard.

Fast sessions, measurable gains. 10 minutes a day. Streaks, XP, and accuracy history show you improving in real time.

Battle mode. Fight five opponents in a gauntlet — each one tests different ear skills with type effectiveness.

No drift. No latency. Audio uses the Web Audio API clock directly — rock-solid timing on every tone.

DAW Pro, AI MIDI, live amp input, cloud sync, full training access, and advanced analytics.
