I programmed a couple of parameters in a VST synth to a controller, set a single note (C1) to play for three minutes and eleven seconds, then recorded the automation. The parameters I was manipulating in real time were the shape of the waveform and the frequency. After recording the automation I added a bit of compression, a nice slow chorus to give it a left to right sweep, and a short delay with a lot of feedback for some added atmosphere. The image is just a snapshot from my photos and has nothing to do with the sound, but you’ve gotta love stick figure warning messages.
