LEMUR – Urban Music-Bots

**LEMUR (League of Electronic Musical Urban Robots)**

Who are the LEMUR bots?

(from the website): LEMUR: League of Electronic Musical Urban Robots is a group of artists and technologists who create robotic musical instruments. Founded in 2000 by Eric Singer, LEMUR creates exotic, sculptural musical instruments which integrate robotic technology. The result is computer-controlled mechanized acoustic musical instruments which can perform music by and with human musicians.

LEMUR presents concerts around the world featuring their instruments, often in collaboration with renown composers and performers such as They Might Be Giants, Jim Thirlwell (Foetus), Morton Subotnick, George Lewis, Ikue Mori, Todd Reynolds, Ben Neill and others.

LEMUR creates interactive installations for museums and galleries featuring musical robots, computer-generated video and motion tracking to create an immersive sonic and visual experience.

LEMUR also creates instruments and installation by commission, including musical robots and unusual MIDI instruments and controllers.

LEMUR is based in Brooklyn, NY and Pittsburgh, PA. LEMUR has been supported by grants from the National Endownment for the Arts (NEA), the Rockefeller Foundation, the New York State Council on the Arts, the Jerome Foundation, the Greenwall Foundation, the Mid-Atlantic Arts Foundation, the New York City Department of Cultural Affairs, the Trust for Mutual Understanding, the Experimental Television Center and Materials for the Arts.

Arduino + MIDI drumkit / Sound Generator

This might be an interesting circuit for the DC Fest Organ. This would be a great starting point for us to experiment with different types of mappings and sensors.

It is an Arduino MIDI Drum Kit and Spooky Sound Trigger from TodBot.com

I really like this site as a reference because it has has interesting and fun projects that can be built to learn the Arduino IDE but you can take these components and create really cool interactive + kinectic + visually/sonically interesting art pieces. Here is some video of the Arduino Midi DrumKit+ Sound Trigger how-to link from above:

I will be posting a few photos/videos of our group’s work on this upcoming project!

Arduino + MidiRouter

This project includes a multplexer and the circuits are supposed to route MIDI.

This might turn out to be a useful circuit. It’s one if f found on the Fritzing Project website and has been translated to English via Google Translate from German). *CLICK* on the image link below to download the associated files for the Project ( Fritzing “virtual Arduino” *.fze file, and associated Processing *.pde file.

Midi Router (By the blogger at http://pallingermusic.blogspot.com/):

Says Pallinger Music guy: “My first Arduino, and at the same first electronics project ever. A router with 5:1 MIDI keyboard interrupt status and LEDn. Intended as a master keyboard hack for my Fatar Studiologic VMK 188 +, but can also be used as a standalone MIDI router’s Studio.

For now, I’ve just finished the keyboard. It consists of five buttons and five LEDn, NXP 4067BP and a multiplexer / demultiplexer, 1N4007 diodes 5x, 5x, and 1x 220 ohm 10k ohm resistors.

Each key has an associated LED. Pressing a button is triggered on the interrupt pin D2 at the Arduino 0th In the interrupt routine is the first of the serial In-/Output 4067 set to LOW, wait 20ms and then ask which button was pressed. This is then stored in the EEPROM and the key corresponding to its LED lights put on.

Next is the MIDI board. In this case a standard MIDI In and MIDI outputs 5 – according to the number keys on the keyboard.”
