RND STEP is a high performance, 3-channel sample & hold module, comprised of 6 separate Noise / S&H circuits in just 4HP.
It has emerged from the combined efforts of video-maker extraordinaire Ben “DivKid” Wilson and purveyors of high-end Eurorack modules, Steady State Fate (SSF), and aims to be flexible and fun – whilst also performing to very high technical standards, something often missing in existing designs.
Each of the 3 channels feature two internal analogue pink noise generators, and two sample & hold circuits – one feeding the unipolar output and the other the bipolar output. The unipolar output always samples its own noise source, and produces stepped random voltages between 0V and 5V.
By default, the bipolar output also samples it’s own noise source – producing bipolar stepped random voltages between -5V to +5V. However, you can override that internal connection by plugging an external signal into the Sample socket. This allows for sampling of external audio or CV signals, and will work with voltages anywhere between -10V and +10V.
RND STEP will operate at slow trigger rates and can generate extended hold times, whilst sustaining the voltage with extremely high precision. At the other end of the spectrum, it will also operate right up into audio rates for creative analogue downsampling effects. When triggered at audio rates RND STEP outputs downsampled and clocked noise tones from the internal pink noise generators. These can then be used for modulation, percussion or sound FX.
Trigger input 1 is normalised across to all 3 channels, meaning that a single trigger could produce 6 unique random voltage outputs simultaneously – of which 3 are bipolar, and 3 unipolar. Having both of these options ensures that you always have a suitable voltage range for the task in hand, without having to resort to additional utilities such as offsets and mixers.
As comparators are used on the trigger inputs, you could even trigger one channel using the output of a random voltage from another channel. This would result in the changes in voltage being be more sporadic, as they would only occur when the fluctuating voltage coming into their Trigger input passes a certain level.
RND STEP is a collaboration between Steady State Fate and DivKid. The potential range of patch applications for RND STEP is vast and a selection of patches are demonstrated in the announcement video below.
- 6 high performance analogue sample and hold circuits split across 3 channels
- Both unipolar and bipolar outputs on all 3 channel
- Highly accurate sampling of external audio and CV sources
- High hold times and low droop rate for accurately sustaining sampled voltages – especially crucial when used with pitch sequencing
- Trigger input normalisation from channel 1 to all other trigger inputs
- DivKid-certified. ’nuff said 😉
