Key Lines

Sheet music and piano practise reimagined

App Screenshots

Open any song.

Key Lines works with any MIDI file. They’re the industry standard, and super-easy to get hold of.

Pieces are displayed as you would play them on a keyboard, so there is no learning curve to get started.

Scroll through a piece for interactive playback to help you either find or study a section.


Section looping

Loop sections. Practise until perfect.

Looping lets you pick specific parts of the piece you want to practise. Just drag the top and bottom handles set the start and end of the loop.

With a loop set up up, you can use the speed trainer to have it start each loop playing slowly, and gradually speed up after each loop. Tweak how slow it starts, and how many loops it takes to reach the full tempo.


Bookmarks

Make your mark. Annotate anywhere.

Bookmarks let you mark out sections within a piece. You can add as many as you need.

Use your finger or Apple Pencil to freehand draw anywhere in the piece to annotate.*

* iPad only


Playback customisation

Customise every aspect of playback.

View every track within a MIDI file, and change the key and tempo to your liking.

Percussion tracks play along side the active track, or can be swapped out for a standard click metronome, or silenced entirely.
