The Distance Music event at Lake Eola October 25, 2014

The distance organ premiered in 2014 at the well attended “Distance Music at Lake Eola for Seven Train Horns and Brass Choirs” concert in downtown Orlando. Horns were donated by Nathan Airchime, powered by nitrogen (N2) gas through seven radio-controlled, solenoid-actuated poppet valves donated by Parker Hannifin’s Pneumatic Division. Funding came from an $8710 Kickstarter and grants of $2500 from the United Arts of Central Florida and $1000 from the Awesome Foundation. This video explains the design of this concert:

In the 22 acre Lake Eola, seven nitrogen powered train horns pitched C,Eb,F,Gb,Ab,Bb and D were each mounted upon a heavy, pedal-powered, 5 seat fiberglass boat shaped as a swan. They were “played” by on/off commands sent through radio signals broadcast from the shore which emanated from a Logic X sequence on a laptop computer. The homebuilt radio broadcaster and 7 receivers at the train horns used an Xbee-PRO DigiMesh 900 using the 902 to 928MHz (ISM) band. They transmitted data at 87kbps – basically offs and ons, to each horn receiver, which was was coded to respond by sending 12 volts to a coil opening a Parker Hannefin Pneumatics N-Poppet solenoid valve when it is addressed in the serial data. The voice communications between the composer, swan boat captains and conductors was provided by a Lectrosonics T4 rented from Tai Audio in Orlando. The conductors received their own, pre-calculated, separate, recorded audio click from the same LogicX sequence that controlled the train horn data. The north ensemble’s click was 0.985 seconds ahead of the south ensemble in the last movement to allow time for the sound to reach the south-shore audience in order to synchronize with the south choir’s beat.

The speed of sound changes with air temperature. Thus, adjustments would need to be made to the tempo of the entire work to maintain the set placement of the horns. This adjustment would be made by changing the tempo on the Logic sequencer according to the chart below. Not only did the sequencer control the horns, it also sent each conductor their own click track with spoken rehearsal letter cues.
