Doepfer A-148 Dual Sample & Hold
NoiseBug Price : $80
module a-148 (dual s&h) has two identical sample & hold modules, designed to produce 'staircase' voltages. the signal present at the sample input is sampled at a rate set by the signal at the trigger input, and held at that voltage at the s&h output.
the exact shape of the staircase depends on the sort of waveform at the sample input: noise or random signals produce random patterns; an lfo produces rising or falling staircase patterns.
two leds for each s&h indicate the voltage (positive or negative) of the sampled signal.
similar module: a-152 voltage addressed track&hold / switch (multiplexer) / digital outputs.
this module has a maximum current draw of 20ma. it requires 4 te/hp worth of space to fit in a eurorack frame.
