What it is
You open a MIDI file, choose how the notes look, and save a video with sound.
Pianists who post their playing usually record the screen of a teaching app or spend hours in a video editor. HearCloselyKeys does one thing: a clean video of the keyboard with the notes of your piece, in the frame your site needs.
Your files stay with you: MIDI, sound and video are processed on your computer and are not sent anywhere.

A look is not a set of colours: each has its own light, backdrop and way of drawing a note.

How it works
Three steps from a file to a video.
- Open a MIDI file
Or drag it into the window. The app works out which hand plays what.
- Choose a look
Notes, effects, note names, captions, a frame for YouTube or for a phone.
- Save the video
MP4 with sound: the app’s piano or your own recording.
Nothing is uploaded: the video is made on your computer.

- Frames for every site
16:9 up to 4K, 9:16 for Shorts, Reels and TikTok, 1:1 and 4:5 for the feed.
- Your own recording
Put your recording in place of the app’s piano and set it in time with the notes.
- Hands and tracks
The right and the left hand in their own colours; a single track is split into hands automatically.
- Note names
On the notes and on the keys: C D E or do re mi, with the octave or without.
- Hall and loudness
A room, a chamber hall, a concert hall or a cathedral; the loudness of the video is set for YouTube.
- Transparent video
Notes without a backdrop, to lay over your own video in an editor.
Questions
- May I post the videos and earn from them?
Yes. The video is yours. On the free plan it carries our mark.
- Whose piano sound is it?
Samples of the Salamander Grand Piano by Alexander Holm, licence CC BY 3.0. If you use the app’s piano, mention the author of the samples in the description.
- Which MIDI files fit?
Any standard MIDI file with piano notes. Best of all - with the hands in two tracks.
- Do I need the internet?
Not for making videos. The internet is needed only to sign in to your account, and from time to time for the app to renew its licence.
