Product Usage Instructions
To use the Analogue Sample & Hold device, follow these instructions:
- Connect the Signal In to the desired audio source.
- Connect the Signal Out to the desired destination.
- Connect the Clock In to a clock source.
- Use the Internal BPM / Tap or External clock input to set the tempo.
- Adjust the Dynamic Phase Alignment and Subdivision Probability settings as desired.
- Use the Increasing Fader to increase the available range of subdivisions and increase probabilistic chance of new subdivisions.
- Use the BPM Fader Control Definition to define the function of the fader.
- Adjust the Clock Probability & Algorithm Parameter settings as desired.
- Use the Button Combinations to perform a Factory Reset, adjust Offset and Attenuation, or select an algorithm.
- Use the CV inputs to control the device with external voltages.
- Use the Pattern repeat function to create up to a 16 step repeating pattern.
- Use the Waveshape Interpolation function for smooth transitions between steps.
- Use the Down Sample function for BPM related down sampling.

Fader Control Definition
The Random Toggle defines the function of the fader.
Button Combinations
- Factory Reset – Press and hold both Shift Button (1) and Tap Tempo Button (2) and switch Random Toggle (3) up and down 3 times.
- Offset and Attenuation – Press the Shift Button 3 times and hold it on the third press. Press Tap Tempo Button (2) to toggle.
- Algorithm Selection – Press and hold the Shift Button (1) to display the currently selected random algorithm. Shift Button (1) and Tap Tempo Button (2) will cycle through algorithms. Algorithms are expressed by animated LED cycles.Ascending patterns indicate 1, 2 and 3. Descending patterns indicate 4, 5 and 6.
Algorithm 1 – Classic Stepped Random
Digitally generated random steps derived from pseudorandom number generation.
This is the most “traditional” random algorithm.
Algorithm 2 – Repeatable Stepped Random
Digitally generated random steps derived from pseudorandom number generation.
Algorithm 3 – Chaos
On each clock cycle, the algorithm might flutter, cycle, wobble, produce a
random control voltage, or drift. Best suited for slower tempo clocking.
Algorithm 4 – LFO
LFO rate matches the tempo, but is not phase-aligned. Tempo/frequency changes
are fully interpolated and completely smooth.
Algorithm 5 – Probability-Synced LFO
LFO rate matches the rhythmically-relevant subdivisions if the clock
probability engine is enabled. Functionally, this algorithm is the same as
Algorithm 4, but the LFO frequency will adapt and follow the
rhythmicallyrelated subdivisions
Algorithm 6 – Downsampled LFO
LFO rate matches the tempo, but is not phase-aligned.
Tempo/frequency changes are fully interpolated and completely smooth.
