Sample/Hold with Arduino as randomizing function

[ghostofjohntoad]

First off a little background.  I've been building pedals for just a year and have progressed to the point of a challenge. I have some electronics background but it's been a bit since I have had courses so I am getting back up to speed reading all I can.   I ordered the TonePad FSH1 board to try my hand on that - as I am extremely intrigued by non-standard sorts of guitar pedals. 

Here's my question  would it be possible to incorporate the arduino as a random generator to supply the FSH1 board?  Like say using a variety of sensors and randomizing that info to feed the circuit.  I envision using light, temperature, proximity, twitter feeds whatever can be sensed really.

I've been looking at a way to incorporate my arduino into guitar related stuff for some time and this sounds like an interesting concept.

Well it could certainly be used in a variety of ways.  One might be to simply substitute for the clock that drives the gate of the FET which lets the noise source through.  The rate of the clock, and even accelerating/decellerating or other patterns of clocking could be achieved.

A second way might be to provide the current for controlling the filter sections directly from the Arduino's output (well, not directly directly but substituting for the noise source and clock).
