Pixelated Oscilloscope History! This mode keeps a record of the last 72 frames of audio input buffer. If an individual buffer value went above the ‘threshold’ (set by Knob3), it will show up as a filled square and scroll across the screen. Shift the record left & right with Knob2. Control the scroll direction with Knob1. Don’t forget to hit ‘Persist’ now and then!
