+
+Playing the video from source:
+------------------------------
+

+
+Recording the video from source:
+--------------------------------
+
+1. Record OpenGL calls

+`renoise 078elektrouschi-video.xrns`
+`apitrace trace ./sv $(cat img)`
+
+2. Convert to video
+
+- Export audio from 078elektrouschi3-external-fx2.xrns (e.g. 078elektrouschi-video.wav)078elektrouschi-video.wav
