RND Step Eurorack Sample + Hold Module

RND STEP is a high performance, 3 channel sample and hold module, comprising of 6 unique sample and hold circuits in just 4HP.

Each channel features two internal analogue pink noise generators, and two sample and hold circuits split across unipolar and bipolar outputs. The unipolar output always samples its own noise source for a stepped random voltage between 0-5V. The bipolar output by default samples it’s own noise source (for -5V to +5V stepped random). However, you can override that connection with the sample input. This allows for sampling external audio or CV signals, and it can sample voltages anywhere between -10V and +10V with the sample input.

RND STEP will operate at slow trigger rates with highly extended hold times, ensuring it holds the voltage with minimal droop, but it will also operate up through audio rates for destructive downsampling FX for audio. 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 will normalise across all 3 channels, meaning a single trigger can give 6 unique random voltages, of which 3 are bipolar and 3 are unipolar. The combination of both ensures you have the right voltages in the correct ranges for the sources you wish to modulate.

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 here:

• 6 high performance analogue sample and hold circuits split across 3 channels- a mixture of both unipolar and bipolar outputs
• Highly accurate sampling of external audio and CV sources
• High hold times and low droop rate for holding sampled voltages
• Trigger input normalisation from channel 1
• 4HP wide
