After Later Audio – SHTH Sample & Hold / Track & Hold

The SHTH module gives you two different kinds of stepped outputs using two classic synthesis techniques – sample & hold and track & hold. All this in the most compact format imanginable!

Sample & Hold

The Sample & Hold section is occupying the top four jacks,. The noise output is normalled to the input so you can directly send a gate or trigger into the SAMP input to get a stepped output at the OUT jack.

• IN - Signal that will be sampled, normalled to NSE output
• SAMP - When high updates the voltage being sent to the output
• NSE - White noise output
• OUT - The sampled output (sampled value from the IN jack when the SAMP jack receives gate or trigger)

Track & Hold

The Tack & Hold section occupies the lower four jacks. The walk signal (a randomly meandering voltage) is normalled to the input. Track & Hold is different from Sample & Hold in that it will pass the input signal to the OUT jack until the TRACK input receives a high gate – this will hold the value until the TRACK input goes low, again. it will begin tracking the IN signal again.

• IN - Signal that will be tracked
• TRACK - When high the value will be held at the output
• WALK - A meandering voltage
• OUT - The track output (follows IN while TRACK is low, held voltage while TRACK is high)
