The Selective Sample & Hold is a simple dual S&H based on the LF398 S&H chip, but with a twist – there are two possible inputs, and a Select input to determine which one will be sampled between the two. With nothing in the Select input, it acts as a standard S&H on input A, but with a high gate or CV signal patched in (about 4v or above) it will switch to sample from input B. The two output jacks are both the same single sample, but separately buffered.
Note: this module does not have its own noise source. You will need to use an external signal to sample for it to work. Nor does it have its own clock, so again, you need an external clock/trigger to use it as well as some gate or other signal for the “select” input.
