"Conductor (2011) by Alexander Chen. Video capture. View live at: mta.me

Conductor turns the New York subway system into an interactive string instrument. Pulling from the MTA's actual subway data, trains pluck at intersecting lines. The piece begins in realtime by spawning trains which departed in the last minute, then continues accelerating through a 24 hour loop. The visuals are based on Massimo Vignelli's 1972 diagram.

Vintage Analog CRUMAR T-1 Hammond vk Clone Organ synth

via this auction
"The sound of the organ is of course, pure 100% analog drawbar perfection. It is super fat, super squishy, swishy and dense, with tons control over the tone (crazy wide and slow LFO for subtle leslie to siren-like detuned chorus effects and enough percussion options to keep you busy for a long time. Indisputably, the T1 was the king of analog hammond-style combo synthesizers, and the flagship of the Crumar line, hence its devoted and increasing following among analog enthusiasts and players, and its subsequent extreme rarity."

Modded Roland GR-33B Analog Bass Synth

via this auction

"The modification on this unit replaces the 24-pin connector with a break-out box that has a single 1/4" input. This allows any line-level signal to run through and be tracked by the GR-33B.
There are also extra knobs on the box that add more flexibility to filter cutoff and resonance and LFO. Because of the modification, the unit no longer works with a 24-pin connector, and only plays monophonic, although all 4 oscillators can fire at once.
Since the unit has been modified and works differently than it's original design I am selling the unit AS-IS FOR PARTS. This listing includes the modified Roland GR-33B unit only."
