A demonstration of running audio through a sample and hold.  The input to the Oakley S&H comes from a little bell patch.  (The Limit control is set to zero, since we want fidelity.)  The clock in to the S&H comes from the square wave output of a CGS VCO.  We are monitoring the output of the S&H.  The demo is in three parts.

The first part is the clean sound of the bell patch, through the S&H!  It is clocked at the maximum frequency of the CGS VCO, which is about 28 Khz.  In the second part I start manually lowering the VCO clocking frequency, pausing in a few places.  Now you can hear the cross-modulation between the audio frequency of the clock and the bell signal.  I leave the clock at about 1 Khz for the last part.  Lastly, I patched the envelope from the bell patch to the VCO FM input to produce a correlated up sweep in the clock frequency.
