The video "Classic Oscillators Part 1" is listed on the web site as "Virtual Analogue Oscillators Part 1". Whichever variant of the title you prefer, the title implies that there is or will be a "Part 2" video. And the Part 1 video's narration says that there will be a Part 2, concentrating on oscillators 2 and 3, as Part 1 itself concentrates on oscillator 1.
I cannot find a "Classic Oscillators Part 2" or "Virtual Analogue Oscillators Part 2" video on the web site. Has the video been produced? If so, where may it be found?
