This new module should not be judged by it’s size, at 6hp it’s packed with features.
At its core it features a noise source and two precision Sample & Holds that drastically reduce the typical voltage drop over time (20 minutes for a 0.01v drop) and with 0.3% of maximum deviation from the Input which allows for quantized signals to be sent through without any noticeable detuning.
The Sample & Hold sections can also be used as a Track & Hold meaning it holds the incoming input while the Trigger input is ON and lets the input flow to the output when the Trigger input is OFF.
Each section also features it’s own slew processor with a single control over attack and decay and an ON/OFF switch.
The noise signal is normalled to both sections inputs, meaning that without a jack plugged into the Input the sample and hold function will act upon the incoming noise signal generating random CV values.
The [Trigger A Alternate] switch allows to Link both sections so that any trigger input in Trigger A will alternate between triggering the A and B section.
Besides each section outputs there’s also 4 extra outputs: Noise, Difference, Average and Sum. The [Noise] output is coming from the noise source, the [Difference] output is the subtraction of section A minus section B, the [Average] output is the sum of both A plus B and then divided by 2 and finally the [Sum] output is the sum of both A plus B sections.
This module will also be available as a full DIY kit.

Here's the detailed step by step Assembly Guide Pdf:
When designing this module we opted for a long slew time, this was decided in order for the slew to be able to smooth out the internal noise source to a slow moving voltage.
It has come to our attention that some users find this fixed slew time range too high and would prefer a smaller range mainly to use the slew as a portamento when using the sample and hold for 1v/oct sources plugged into VCOs.
We will keep our initial slew range as a default but user's can now request the shorter slew range when buying directly from us.
We also added both capacitors to our DIY kit and added all info on our Assembly Guide pdf. This will also allow experienced users to make this change themselves.
Beware that desoldering the smd electrolytic capacitors isn't an easy soldering job as it may lead to breaking some pcb tracks and thus rendering the slew function unuseable and hard to repair.
We can't offer any warranty if you accidentally damage your pcb.
