![]() It is known to separate the " Old World" of Africa, Europe, and Asia from the " New World" of the Americas in the European perception of the World. It covers approximately 20% of Earth's surface and about 29% of its water surface area. The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about 85,133,000 km 2 (32,870,000 sq mi). The pass starts from just northeast of the island of Newfoundland over the North Atlantic Ocean to central Africa, over South Sudan.

Changes: changed to full screen, updated for Processing 3, added colour, added rectangle and star shapes The code for the sketch is shown below //Visualiser for use with Sonic Pi 3 written by Robin Newman, September 2017 These can be timed appropriately with the musical content. The final setup works well with Sonic Pi 3, which controls the patterns both with the Audio signal it produces, and also with OSC messages which can be sent to the sketch display code. I added further flexibility such as the ability to rotate the shapes, and to shift the whole display vertically and horizontally across the screen. I then added some code so that the sketch could receive incoming OSC messages sent from Sonic Pi 3, which could be used to control various parameters for the shapes, such as stroke width, colour, and offsets on the screen. I added rectangles and star shapes and experimented with off-setting these as the program ran, and also with using more than one basic shape at the same time. I experimented with adding further basic shapes to the display (it originally used an ellipse primitive, set up to give concentric circles, which could also be driven to produce a star burst effect). I played around with this, upgrading it to work on the latest version of Processing, and added some colour. It was written several years ago and was only monochrome based. I did a trawl of the internet and came across a promising looking processing sketch which produced a pattern which reacted to incoming audio. The recent arrival of Sonic Pi 3 allowed for further possibilities, because it enabled the use of OSC messaging. I did some experiments with the iTunes visualiser which added quite a nice backdrop, but only with a significant delay between the audio and the fluctuations of the display. The built in Scope can give attractive displays, but I wanted something with a bit more colour, and which covered the whole screen. ![]() Every since Sonic PI had a transparency mode added (not available on the Raspberry Pi versions) I have been interested in adding a Visualiser graphics display as a backdrop. ![]()
