## What is MIDI Memo Recorder?

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 www.line6.com/mobile.

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.

### 1/5 — Please modernize!!

*2018-08-28*

Got an adapter for my iphone 7 to use the cords, just need the software to update!!

### 1/5 — Line 6 Abandoned its MobileKeys Customers!

*2016-03-29*

I thought Line 6 was better than this! Line 6 stopped updating this app long ago. It does not work (without undocumented hacks) under iOS 9. C'mon Line 6!

### 1/5 — Ne reconnaît pas tous les claviers!!!

*2015-05-25*

Mon clavier USB-MIDI Midistart Music 25 n'est pas reconnu. 
On ne peut pas mettre zéro étoile. Dommage...

### 3/5 — Buggy

*2015-04-26*

Works but not always. Has yet to be updated for new iOS screen sizes, which makes it feel like it has been abandoned.

### 1/5 — Merci Apple

*2014-11-11*

1 étoile pour Apple
Merci Apple de faire que les accessoires que l'on achète cher se retrouvent du jour au lendemain plus compatibles et donc inutilisables.
Les amis avez vous trouvé une solution pour que le midi mobilizer 2 soit à nouveau compatible?

### 1/5 — When it works, it's excellent.

*2014-10-26*

I use this with my mobile keys 49, and when it works, it's great. It is compatible with almost every great synth app out there, and is very stable and user friendly.  Unfortunately, any time there is an iOS update, it completely stops working. This app almost never updates, and leaves the user to troubleshoot when hardware doesn't work. If this worked with every major mobile os, i would give them some slack, but issues should be resolved without making a user wait for 8+ months each time. It's very very frustrating.

### 1/5 — màj, vite

*2014-05-06*

fonctionnait très bien sur iphone 4 jusqu'au passage à iOS 7....
Vite, une mise à jour, que je puisse de nouveau
"jouer" avec mon mobile keys !
merci

### 1/5 — Ne marche plus ......

*2014-04-29*

Mon clavier mobilkeys n'est plus reconnu par mon iPad et GarageBand. L'orque j'ouvre l'application line 6 il me dit qu'il manque une interface mais je ne trouve pas. Déçu.

### 1/5 — Gig nearly ruined

*2014-04-20, version 3.0.4*

This software is required to make the Line 6 midi mobiliser II work. After 7 solid rehearsals with it triggering Nanostudio, my iphone 4 reports "This device is not supported by this phone" ... ON A GIG whilst setting up.  Nanostudio can't now see it.

Thankfully, as a pro I have backup solutions on which I can truly rely. If you're a pro do not use. You don't know when you be left stranded.

### 4/5 — Worked fine for me

*2014-02-10*

I installed this app into my iphone 4 to use my new line 6 mobile keys 25. Out of the box it would not work with a 3rd party synth app saying that my device was not supported on my phone. I installed this app and updated the firmware and she works like a champ! Fast and easy. As far as the recording ability built into this app, it seems very vanilla and I don't expect to use it much.
