Hello,
I was thinking about waveform and sound of the theremin. For a musician's ear, I think it's pleasant low sounds more sharp-like wave, and high ones more like a sine wave. It's not easy to achieve this when you set one waveform position for all octaves on your instrument. Have we any device (like synthesizer) where you can set for example more sine wave above selected frequencies and more sharp wave under selected frequencies?
Thank you for your ideas!
