«Synchronous control bus visualizer using the shared memory interface» by rukano

on 29 May'12 00:53 in synchronizationcontrol busaudiovisualanimated user interface

Messing around with Control buses and later Control Ndefs and using getSynchronous to use the exact value of the UGen in the draw function. Extra: you can click on the zone of the moving circle to pause and resume the running synth on that bus :)
