Record what you play

Play a few chords on your MIDI keyboard and the app recognizes them and turns them into an exercise.

Press R, then play

The app already listens to your keyboard to check your answers. When you record, it writes down what you play instead of comparing it with a question.

Press R and play. The app recognizes each chord when you let go of the keys: it works out the root from the bass note and the chord type from the spacing, so inversions are recognized too. The counter in the corner goes up by one for each chord.

The practice screen while recording, with a red dot and the counter at 2 of 50 in the corner. — Recording in progress, with two chords so far on the counter.

A close-up of the recording indicator: a red dot and the count, three of fifty. — One recording holds up to fifty chords, enough for a whole song.

Stop recording to get an exercise

Press R again to stop. What you played becomes a Songs exercise with the chords in the order you played them. You can drill it, loop it, transpose it or share it as a link, and you never had to type a chord name or pick one from a menu.

The practice screen after recording: the chart reads C, Am, F and the first chord is the question. — Three chords played on the keyboard, written down as C · Am · F.

If a song is stuck in your head, play it once from memory, stop the recording and practice the chart the app wrote for you.

How it tells one chord from another

When you let go of a chord, the app lines the notes up from the lowest, measures the gaps between them and looks the shape up in the same table of chords it drills you on: triads, sevenths, ninths, suspended chords and intervals. Then it works back from the bass note to the root, so E–G–C is recorded as C major with E in the bass.

Doubled notes count once, so a C in both hands or an octave in the left hand makes no difference.
A shape that is not in the table is skipped rather than guessed. Nothing is written down, and you can go on to the next chord.
The same chord twice in a row is written once, so you can hold it or strike it again without filling the recording with copies. To drill each chord several times, turn on repeat each chord in the result.
Chord names follow your Preferences: inversions appear as C/E or C.1, whichever you chose.

Chords or a melody?

You can record in two ways:

R records chords. Two or more keys pressed together make one entry, and a single key on its own is ignored. Each entry in the result is graded as a whole chord.
Shift+R records a melody. Every key is one entry and the result is graded note by note, so a tune played one key at a time becomes a melody drill instead of a string of two-note intervals.

Use the first for a song’s accompaniment and the second for its tune in the right hand.

The practice screen after a single-note recording: the chart reads G, F, E, D, C. — Five notes recorded one at a time: G, F, E, D, C.

`R`	Start or stop chord recording
`ShiftR`	Record single notes (a melody)

What it needs

Recording needs a MIDI keyboard. It listens to the keys you press on the instrument, so the naming mode cannot be used to record. If no instrument is connected, R tells you so. Connecting a keyboard takes one cable.

The app reads a chord from the shape of its notes and ignores the key signature. C major is C major wherever you play it, and a chord with its third in the bass is recorded as an inversion.
