Lemur is the world's best MIDI/OSC controller for iOS. Benefiting from nearly 10 years of development, Lemur is synonymous with multitouch music control. All these major artists can't be wrong: Daft Punk. Björk, Plastikman, CHVRCHES, Glitch Mob, Sub Focus, Max Cooper, Barker & Baumecker, Orbital and many more.

Version 5.0 introduces the incredible new Canvas object and the Sequencer family of features with rock solid timing.

Canvas — Canvas is a brand new object that lets you script custom widgets with full multitouch support. The object is adapted from the HTML5 Canvas element, which means you can design widgets featuring complex shapes, animation, shadows, and transparency The Canvas object opens the door to a completely new Lemur experience, where the appearance and behaviour of objects can be designed to precisely match the demands of your project. Polygons, waveforms, circular objects and infinitely more are all possible with Canvas.

Sequencer — Lemur 5.0 introduces a family of new features for tight sequencing. This includes three new objects: StepNote, StepSwitch and StepSlider. Each of these provides a different flavour of sequencing and is ready to use right out of the box. The objects do the hard work for you, simply add them to your template and they are ready to control your MIDI instruments.

In App Editor — Design your templates on the fly, without a computer in sight. The In-App Editor, available on iPad only, makes multitouch control truly improvisatory by letting you shape your controller the same way you shape sounds. Virtually every function of the desktop editor application is now available through an intuitive system of iOS menus and widgets. Best of all – it’s easier to use than ever. This means a much smaller learning curve and an immediate initial experience. Any basic configuration, such as a typical bank of faders, can now be created with a few familiar taps and gestures. And any factory template can be adjusted quickly to suit your particular needs.

Skins — Lemur features three new skins, in addition to the classic look. Choose the look that fits your style and get inspired.

LiveControl 2 — Experience the ultimate Ableton Live controller, designed in partnership with master designer ST8. Improvise a riff on the Play page, then switch to the Sequencer page to edit the pattern. Choose a key and scale to guide your melodies and use Quick Chord to instantly create harmonies. Use the Modulate page to flawlessly map any parameter from any plugin to the MultiBall object and take advantage of Physics, LFOs and gesture recording. The Launch page gives you everything you would expect from a clip launcher, and more. We even integrated snapshots and morphing.

REQUIREMENT (for the Lemur Daemon):
- OS X (Intel only) 10.5+
- Windows (XP SP3 or 7 recommended)

The In App Editor feature is accessible only on iPad devices.


Simply connect your iPad/iPhone to your laptop over Wi-Fi and make the connection! Lemur also supports CoreMIDI allowing you to use hardware interfaces such as Alesis' iO Dock or the iConnectMIDI or class-compliant USB MIDI interfaces (with a camera connection kit). You can even control up to 8 computers from one iPad with Lemur!

Amazing tool even if imperfect

Nothing does what lemur does really. There are other midi template creators but the scripting depth in lemur makes it immensely powerful. Sure, the editor is clunky and the language is (often frustratingly) limited. But it is also the most used app on my iPad and a core part of many of my music performances.

Many of the bad reviews are from people who misunderstand the tool and its depth. If you aren't at least somewhat fluent with programming concepts you make hit a brick wall with lemur, but that is not the applications fault as much as a representation of what it achieves: stable customizable creative audio control.

P.S. If I was going to fix one thing in lemur, it would be improving the step sequencer objects. They play poorly with external sequencers, cannot be paused or reset easily and are not solid enough for reliable live use. Maybe I'll dig into the canvas object someday and work around this on my own.

Best App I Own


This app is incredible. It works flawlessly (if you know what you're doing), it's beautiful to look at and the possibilities are endless.

I have absolutely nothing bad to say about Lemur. This version seems to be rock-solid and works immediately as soon as I boot up Ableton, which is all I really ask for (other apps of this nature can be kind of a nightmare to get going, and nothing kills inspiration like troubleshooting.)

The only feature request I can think of is it would be nice if every controller showed its assigned MIDI Output Message while you're in Edit Mode. While I'm duplicating buttons and whatnot, sometimes I forget to change the assigned output and I end up with two controls doing the same thing. This is such a minuscule thing to gripe about I feel a bit embarrassed bringing it up.

Thank you to the developers for this unbelievable software. It blows my mind that we live in a world where stuff this cool exists.

couldn’t get anything to work, waste of time

I couldn’t get anything to work, a total waste of my creative time. The OSX editor, needed to upload templates onto the iPad doesn’t work with my external monitors plugged in, connections to the ipad from the editor were always “busy”, the documentation is insulting with remarks like “connection are simple and easy” when in fact there is a substantial list of everyday reason that their software connections don’t work, like apparently in one place they tell you to make sure your bluetooth radio is disabled. Honestly, this developer seems like they live in a bubble and are totally clueless to the new user experience. Good luck, wish I could get a refund.
