Sequencers allow you to compose a melody just by drawing the notes onto a 2D grid, virtually turning anyone with a moderate feel for pitch and rhythm into an electronic music producer. For [Yuvi Gerstein’s] large-scale grid MIDI sequencer GRIDI makes music making even more accessible.
Instead of buttons, GRIDI uses balls to set the notes. Once they’re placed in one of the dents in the large board, they will play a note the next time the cursor bar passes by. 256 RGB LEDs in the 16 x 16 ball grid array illuminate the balls in a certain color depending on the instrument assigned to them: Drum sounds are blue, bass is orange and melodies are purple.
Underneath the 2.80 x 1.65 meters (9.2 x 4.5 foot) CNC machined, sanded and color coated surface of the GRIDI, an Arduino Uno controls all the WS2812 LEDs and reads back the switches that are used to detect the balls. A host computer running Max/MSP synthesizes the ensemble. The result is the impressive, interactive, musical art installation you’re about to see in the following video. What better tune to try out first than that of Billie Jean whose lighted sidewalk made such an impression on the original music video.
Ok, that’s impressive…
No comments? Seriously?! This thing is cool!

Unfortunately, the actual site is down so the software is not available.
This is great fun to watch, the colored balls and lights from the table look really attractive and fun to play with. But the bottle caps build is just as fun and very inspiring from a technological point of view. Thanks for posting.
I’m loving this!
I want to see it in person. Really hope this idea spreads like fire. :)
I wonder why it is stretched not square. Perhaps to double it’s density later, otherwise it’s an exercise run.
Who else thinks this thing would create huge lines in a science centre?
I work at a science center. Can confirm. Lines would form.
