Simillion This is good. He probably uses scale correction and tempo fixing and he seems to be using the theremin to play samples but still great Melody and style and deserves props
betabox It doesn't seem at all to be a theremin. You can definitely see that there's a light source and a light receptor being used as a trigger for the 'laser' sounds, and I see no relationship between distance and pitch.
Simillion agreed, either weird type of theramin with software support making it a non-analog instrument at that point (i.e., not a theramin functionally) or just not a theramin, probably mislabeled video.
HonkeyKong The video title is now Laser Harp which, by name alone, deserves 5 stars .
