Maul's Sample and Hold (S+H) function is designed to output a stream of varied modulation values which are produced by taking the value ('sampling') of a dedicated internal noise source when it receives a pulse from its internal clock. The value is 'held' constant until the next clock pulse occurs.

It effectively performs the function of a 'random LFO'.

The S+H module's Visualizer represents the real-time output of the module.

s+h2

With the Sync button enabled, the Rate control is set in BPM values derived from the tempo of the host within which Etch is running.

With the Sync button disabled, the Rate control is set in Hz.

Rate

The S+H function is driven internally by a series of pulses called a clock, the speed of which is dictated by the Rate control. When a clock pulse occurs, the dedicated internal noise signal is 'sampled' - its current value is 'snapshotted' - and held constant at the sampled value until the next clock pulse, when the process repeats.

Slew

The Slew control introduces lag between each sampled and held value, resulting in a smoother transition between values instead of abrupt changes with the control at the minimum setting.

Gain

The Gain control offers a final attenuation control for the output of the module before it enters the TransMod modulation system. At 100%, no attenuation is applied to the output modulation signal.

This control is intended to be modulated by other TransMod sources, in a similar way to using a VCA to scale one modulation source with another in an analogue modular system.
