Mrmr ( is an ongoing research project to develop a standardized set of protocols and syntax conventions to control live installations and multimedia performances via mobile devices. The project was begun by Eric Redlinger, then researcher-in-residence at the Polytechnic Institute of NYU's experimental media center. The project is open-source and the code base is freely available at

Mrmr enables you to use ordinary cell phones and PDAs as controllers in audio-visual performances, or to participate in interactive museum exhibits, or to use your mobile device in the place of the mouse or trackpad from your full-size computer. It also makes a great, free OSC controller for Max/MSP, VDMX and other VJ/DJ software.

Key elements of the Mrmr project are:
• create your own interfaces using only a text editor
• multiuser by design / client peer-to-peer or client-server models supported
• open standards (zeroconfig/bonjour/mdns, OSC)
• dynamic interfaces: widgets can be reconfigured 'on the fly'

It's an amazing idea for an app but it has many bugs

Learn French Please ,

Great start -

I've been following this app for awhile. Now I don't have to think about spending money on a lemur =) A few problems for me on windows, bonjour doesn't really work for zero network config - but that's ok - I just point mrmr at the IP address and I can use it in Max no problem. Please get us the documentation on interface building. I'm trying to write banks by hand ( no mac here so can't use the bank builder app) oh and a hint for the guy trying to figure out how to make four banks use |*| to separate your banks in hand coded banks.

My wish list:

* two way control - I'd like also receive messages from my computer as well - turning buttons on and off and such.

* A way to upload buttons (for us non-jailbroken)

* More than one color type for buttons.

* Dials, switches, and numerical readouts of values.

* Accelerometer data - I really don't need it unless I ask for it - having it run all the time is kinda annoying.

Good start

I love this app. I am hoping to use it as a remote control for the Make Controller, but the accelerometer support is really slow. It could also use more documentation. When I wrote this review the app had been out for only a couple weeks so far. Even at this rough early state though it is better than the other OSC remote controllers out there. I would pay money for this, but even better - it's free!
