The SMOMID is a unique interface/musical instrument created by Nick Demopoulos. SMOMID is an acronym for “String Modeling Midi Device.” SMOMID hardware resembles a touch-sensitive guitar or bass. Its software allows the performer to control numerous aspects of a performance, including the playing of melodies and harmonies, the direction and pattern of a melody, controlling beats and bass lines, triggering samples, manipulating audio files, and more. All aspects of a performance can be controlled from the grid on the fret board and the buttons on the instrument body. In addition to emitting sound, SMOMID also emits light that is rhythmically in sync with the music the instrument is then creating.

The first SMOMID, completed in 2010, had four strings. The second SMOMID, completed in June 2012, has nine membrane potentiometers that function as strings, two joysticks, eleven high powered LEDs, several force sensing resistors, sixteen buttons and two Arduino Mega micro controllers that allow all of these sensors to interface with a computer or other midi device.

In 2013, this project grew to include two additional controllers called pyramidis that incorporate a dynamic and interactive visual component. Lights on these devices interact with musical rhythms and timbrel aspects of music created with the SMOMID. They also provide additional control surfaces that allow Nick to incorporate “Machine Learning” and other algorithmic type processes in real time.

The SMOMID was created out of necessity. Despite the fact that the guitar is the most popular instrument in the world, there are almost no guitar-like midi controllers commercially available. But make no mistake, The SMOMID is not a guitar, nor is it a substitute for a guitar or a shortcut to creating sound. The SMOMID is a new and unique interface. Like all musical instruments, it has its strengths and weaknesses, and requires patience and practice to master.

The Smomid has been featured in Guitar World, Guitar Aficionado, Warper Party Radio, Create Digital Music, BOMB Magazine, Popular Noise Magazine and Metal Injection. The Smomid made it's debut performance in 2010, and since that time has been featured at the In/Out 2011 Festival, SXSW Music Festival, Dixon Place Theatre in New York, WNYC's Greenspace in New York, the Interactive Music New York Festival, Handmade Music New York and the 2010 and 2013 World Maker Faire among others.
