Exponental/Linear Modulation of Phase, + new circuit idea

[jhaible]

I fully agree with that. Wrapping the modulation voltage on an analogue
all pass filter would be something very different. In order to try Sean's
method in analogue hardware, I suggest a BBD line, a multiplier, and the
waveshaper stage.
