JazzMutant Lemur & Lectro DM84


Sergio Sanmiguel

Recommended Posts

I was reading the article about Sound Super Michael Bergman with the Lectrosonics DM84 Matrix Mixers and they mention that the controller used was the JazzMutant Lemur But the thing is that the "Lemur" communicates with ethernet devices & there's no ethernet port on the Lectro DM84 Mixer... 

Any idea on how was this accomplished?

The lemur-software can be set to communicate with other programs on the mac or simply MIDI. You need a host in between.

From the flyer:

--------------------

A comprehensive macro utility greatly expands the

remote control capability. The DM84 can be remotely

controlled using commands sent over USB, a serial port,

or a network connection. An extensive text-based com-

mand language is defined for the DM84.  Touch panel

controllers, for instance, use this command interface.

Macros are predefined groups of commands that are

stored internally by the DM84. All of the commands

contained in the macro can then be executed by issuing a

single Run command to the DM84. There are two advan-

tages to this approach:

Thats from the Lectro site right? I guess I didn't read that part... Makes sense.

Thanks!

Your speculation above, Sergio, is absolutely correct.  You need a laptop between the Lemur and the automixers. The Lemur speaks and understands a protocol called OSC - essentially MIDI 2.0 run via CAT-5. There is a piece of software associated with the Lemur called the JazzDaemon that translates between the higher-bandwidth OSC into serial MIDI messages which are then -as far as what the Lemur was designed to do- supposed to go to various MIDI musical instruments. We wanted to use those MIDI messages to dynamically remote control Lectro's  AutoMix/Matrix box. Unfortunately, Lectro's machines don't speak MIDI, - but they do speak a serial protocol and, indeed, they are designed to be remote-controlled.  What you then need is a mechanism to parse MIDI into LecNet - which didn't actually exist until  misunderstood genius Peter Schneider wrote it from scratch over the course of a few days instead of sleeping.

      So that's how you hook up the Lemur to the DM84. It's a massive pain in the ass. Especially considering that there are other, off-the-shelf control devices (Crestron) that speak directly and natively to Lectro's machines and would have kept us from reinventing  the wheel. We found the latent possibilities within the interface inspiring enough to warrant this added complexity. I love that thing.
