Please Note: The MIDI* record and play features of this free app require a hardware MIDI accessory from Line 6: a Mobile Keys 25 or Mobile Keys 49 keyboard, or a MIDI Mobilizer II or MIDI Mobilizer MIDI interface. For more information on these products and the many compatible MIDI apps, please visit

MIDI Memo Recorder simply records and plays any MIDI data - any time, any place. The app's streamlined design makes it quick and easy to store, find, recall, and even email any type of MIDI information - all your synth sounds, Line 6 effect patches, musical inspirations, and more. And with iOS version 9.3 and higher, MIDI files can also be transferred between your mobile device and your computer using iTunes File Sharing.

When the MIDI Memo Recorder app is used in conjunction with the MIDI Mobilizer II and MIDI Mobilizer hardware MIDI interface accessories, it's compatible with every single product equipped with standard 5-pin MIDI connectors. That means literally millions upon millions of keyboards, amplifiers, effects devices, and other types of audio gear throughout the world.

The MIDI Memo Recorder app also serves as the firmware updater for Mobile Keys keyboards, and for the MIDI Mobilizer II and MIDI Mobilizer MIDI interfaces. That means you can always get the latest firmware simply by updating to the current version of the MIDI Memo Recorder app and running it.

* "MIDI" stands for Musical Instrument Digital Interface, the worldwide standard for communicating musical performance data between musical devices, computers, and mobile devices.

All You need from a simple MIDI librarian.

I think this turned out to be one of the most handy music tools for ios I have.

Installed and got it working with the mobilizer 2 on both the ipad2 and iPad touch - recording, saving and sending sysex dumps in about a minute.

At first I thought installing it in order to use the mobilizer was an obtrusive nuisance but I'm using this a lot as a backup buffer when sound designing, so it's turned out to be really a nice bonus app with the mobilizer.

Solves a need brilliantly, a few more features please

For years I've wanted something that could quickly record an idea I had on my Yamaha Disclavier, a piano with Midi. All laptop solutions sucked because by the time I booted up, started a sequencer, configured it, got it ready to record...the inspiration was gone. And if a new virus pattern had to be downloaded, arrgghh.

This thing is absolutely immediate. Instantly works. (this says something about the whole idea of apps versus a bloated, general purpose PC).

For me, I would like what the other reviewer requested: a way to get existing midi TO this app. And his categorization ideas is good.

Otherwise, I am extremely happy with tnhe concept and it makes a great use of old iPod Touches or iPhones when you upgrade to new ones.
