This is my new VCV Rack module called Sapphire Tube Unit. It is now available in the VCV Rack Library:
In this demo, I show the basic functions of Tube Unit as both a synthesizer and an effect filter. I recommend using headphones to experience the stereo field. You can also watch the scope to see how the left channel and right channel output relate to each other. This reveals how Tube Unit’s output is really a complex number, where the real part is the left channel and the imaginary part is the right channel.
