One take, mistakes and all — that’s what the feedback looks like in practice.

Each one gets the same treatment: you play it, it checks every note against the target, and it tracks how you’re doing.
Pick a voicing — inversions and drop-2 included — and play it in any of the 12 keys. Notes turn green as your fingers land; it catches wrong inversions, missing notes, and extra ones, not just the chord name.
Load a progression, set a tempo, and a playhead walks you through it in any key. Run it timed against the click, or self-paced so it waits for each chord before moving on.
Loop a melodic line or a scale run slow, then speed up as it locks in. It anchors to whatever octave you play in, and you can comp underneath without that counting as wrong.
Every voicing you drill becomes a set of cards — one per key — scheduled with FSRS, the same spaced-repetition method behind serious flashcard apps. Clean reps space out; the ones you fumble come back sooner. Open the review queue and it hands you what’s due, weakest keys first.
Today this schedules voicings. Progressions and melodies show in the review view too, with full scheduling on the way.
Drill mode picks the keys, leaning on the ones you’re weakest in. Play a key cleanly enough and it unlocks the next; as your accuracy holds, it nudges the tempo up. A mastery strip shows all twelve keys, each shaded red to green by how solid it is.
ChordLab finds your MIDI controller on its own — no driver hunt. No keyboard around? The on-screen keys are enough to try it out.
Choose a voicing, progression, or melody, set the tempo, and decide if you want it timed or looping. Takes about ten seconds.
Notes light up when you nail them. It counts your reps and accuracy, so you can tell whether you’re improving or just repeating the same mistake.
Keyboard up top, library on the left, practice on the right. No menus to dig through mid-session.
