Oh right... sample and hold is an analogue circuit that will sample a momentary frequency and hold it until it gets a new trigger then it will sample another momentary frequency and hold.
Usually it is used by triggering it periodically or on beat and then a noise is feed in so the output is random but rhythmic tones.
You can send in pitch sweeps and then make a staircase like effect of a pith tone rising rhtyhmically.
If you trigger at audiorate it can be used a bit like a bit chrusher.
In the analogue world a sample and hold is often used to programmatically switch between sets of sequences - so that if the output of the S&H is High or above 5 volts then the output is high so play the top sequence if the output of the sample and hold is low then play the 2nd sequence.
In Max/Msp you can use the output of sah~ to drive timed envelopes - used a lot in granular synthesis.
For a more analogue overview of Sample and Hold try this vid -

Here's a rough idea - the last one is not right but I had to go before I could finish it but I thought I'd post it anyways in case it is of some use....
