MIDI Editor - Music Sketchpad

By Nikolozi Pty Ltd

Open iTunes to buy and download apps.


MIDI Editor turns your iPad, iPhone, and iPod touch into a music sketchpad. Quickly and easily compose melodies, chord progressions and even drum patterns. It works with your favourite synths and music apps that support MIDI input. Once you are done, export the MIDI clip to other apps.

• Three simple note editing modes: pencil, edit and velocity.
• Add and remove notes with taps.
• Precisely edit a note's position and length on the timeline by zooming in to its exact location.
• Select and edit multiple notes at the same time.
• Cut, Copy, Paste, Select All and Delete supported.
• Velocity Mode: Select notes and drag your finger vertically to adjust their velocities.
• Transpose entire clip by +/-24 semitones.
• Undo/Redo edits.
• Adjust grid’s vertical and horizontal zooms independently.
• Import MIDI files from the other apps via Open in... *
• MIDI clips sync via iCloud.
• Export the MIDI files to other apps such as Dropbox, AudioShare, Cubasis and Mail.
• Change which app the MIDI Editor controls by selecting a MIDI Output.
• Background Audio Mode: MIDI clip continues looping in the background while you tweak synth's parameters.
• Adjustable Tempo and MIDI Clip length.

Note that the app itself does not produce any sound. It sends MIDI note messages to Core MIDI compatible apps.

* If a MIDI file consists of multiple tracks they will be imported as separate clips. At the moment maximum imported MIDI clip length is 32 bars.

Customer Reviews

Lightweight, powerful MIDI Editor

I don't understand some of the negative reviews for this app. This is a not a synthesizer; it does not make sound. It's a powerful MIDI editor in a 1MB file size app. Yes, the piano roll grid can be a little tricky at first to figure out. But all the functionality is there. It does polyphonic notes. It does copy/paste, and group transposition. Zoom in and touch the left side of notes to move the note, or the right side of it to lengthen/shorten.

But the killer feature of this app is the ability to open raw MIDI files (thousands of which are all over the internet, or you can create your own with other programs), and then allow you to edit them, re-export as MIDI files, OR control other apps in real-time using Virtual or CoreMIDI (for hardware).

Despite the simplistic interface, the app has worked great for me. Some caveats - "Open in" only imports 32 measures right now. This is clearly indicated in the app description, but I hope to see it increase. Also, the app only controls one MIDI track at a time. I do not believe you can control multiple apps using different MIDI "channels". But for what the app does, it is phenomenal. Hope to see continued work on the app, as it will be used on all my devices.


very good midi editor. which i could have two clips going at once though, or even two different synths/apps going at once! then again it would just get too complex. cant complain though. very simple and quick interface :)
