Hi all,

I implemented a LFO random for the VCF. Though, my pseudo random
number generator is not great. I'll have to find a better one but it
works. I've also implemented it with depth control using parameter 84.
I like the sound of doing a chromatic randomise. I'll have to think
about how to implement that though. The problem right now is that the
LFO applied to the DCO only shifts the frequency up or down ONE
semitone. So the LFO really doesn't push the DCO frequency much at
all. That's why I've not bothered to do the random on it at this
point. So when I develop the second LFO, I will write code to support
pushing the DCO frequency across a wide range. We know the hardware
can do it because the joystick is able to flex the DCO a full octave.
