Moog Sample & Hold
Capture voltage snapshots for stepped random melodic mayhem
4 HP Eurorack module
The Sample and Hold module captures an instantaneous voltage from its signal input each time it receives a trigger, then holds that voltage at its output until the next trigger arrives. Musically, it excels at generating stepped, random melodic patterns when fed noise, or rhythmically quantized control voltages when driven by an oscillator or sequencer. It is a classic generative and modulation tool central to unpredictable, evolving patches.
Features
- Samples and holds instantaneous input voltage on each trigger event
- Internal clock with adjustable Clock Rate for self-contained operation
- External trigger input for synchronization with sequencers or other modules
- Glide control for smoothing steps between held voltage values
- Trigger selection switch to choose between internal clock and external trigger
- Signal input accepts audio or CV sources including noise for random melody generation
- Held output voltage remains stable until next trigger arrives
- Can be used to create stepped random control voltages when fed white or pink noise
- Can quantize a continuously varying signal into rhythmic steps when driven by an oscillator
Controls & Jacks (13)
- Clock Rate — Sets the internal clock frequency (0.3–30 Hz) for sampling when using internal clock mode
- Clock LED — Green LED that blinks in time with the internal or external clock
- V-TRIG — Voltage trigger input for externally clocking the sample and hold
- Int/Ext — Selects between internal clock (Clock Rate knob) and external trigger input
- Pulse — Pulse output synchronized with the sample clock
- S-TRIG In — S-trigger (short-trigger) input for legacy Moog trigger format
- S-TRIG Out — S-trigger (short-trigger) output for legacy Moog trigger format
- TRI — Triangle wave output from the internal clock oscillator
- Glide On/Off — Enables or disables the glide (portamento) circuit on the output
- Glide — Sets the glide/portamento time (msec to sec range) for smooth transitions between sampled values
- X-1 — Signal input (unity gain) to be sampled and held
- X-3 — Signal input with 3x gain amplification before sampling
- Out — Main output of the sampled and held voltage, with optional glide applied
