Module A-148 (Dual S/H) has two identical sample and 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.

For each sub-module the operation mode S/H (sample and hold) or T/H (track and hold) can be selected by a jumper. In T/H mode the output signal follows the input signal while the trigger input is "high". As soon as the trigger input turns to "low" the last voltage is stored. The factory setting is S/H for the upper device and T/H for the lower device.

The small module combines three functions already available in Doepfer's dual modules: ring modulation, sample & hold and slew limiting.

It is recommended for compact systems where space is an issue or for users who don't need two ring modulators or two slew limiter for instance but a small and multi-functional utility instead.

The upper section consists of a half of a A-114 ring modulator and has inputs for the signals X and Y. The X*Y output emits the multiplied / ring modulated signal. The bottom section is a sample & hold followed by a slew limiter. It has an input for the sample signal and a trigger input. A switch select mode of operation as the module can work as a sample & hold or as a track & hold. When in T&H mode no trigger is applied this section can be used as an individual slew limiter.

Simply put, Arpitecht is a voltage controlled Quantizer and rhythmic arpeggio generator.  As one of our most musical modules to date, Arpitecht is designed to be an inspiring tool for the modular musician.  

With Arpitecht, you can create intricate melodies that span 8 octaves, imply chord changes, instant acid basslines, evolving generative sequences, and, using the Triad expander, polyphonic chord generation.

Arpitecht features 16 scales, each with a unique set of "note masks" offering hundreds of note combinations with the ability to dial in via knobs on the front panel or CV. 32 rhythm patterns and 32 slide patterns all with CV control let you feed a static clock into it and get unique, evolving patterns of gates and note changes.

Triad expander module allows you to create uniquely voiced chords in the same key underneath your arpeggios. 

Features:

• Voltage controlled Quantizer and Arpeggio Generator.
• 16 scales
• Hundreds of note combinations possible
• Inspiring to creativity and easy to "land" somewhere new
• 5 octave range arpeggiation range
• +-1 octave transpose range
• Intuitive front panel and "keyboard" LED layout
• Rhythm and Slide Rhythm options for added variety to your arpeggio

Erica Synths Black Modulator is a fully analogue modulation and noise source.

Features

• LFO with sine, triangle and pulse outputs
• LFO/Audio range switch
• Zener diode-based noise generator for massive, full spectrum white noise
• Pink noise filter
• Noise crush knob and crushed noise output – fade from 1 bit noise to individual random trigger bursts
• Clockable sample and hold circuit.
• S&H circuit based on rare, high quality S&H chip
• S&H CV and clock inputs

This module has LFO/audio frequency oscillator with three simultaneous waveform outputs, Zener diode-based noise generator with three noise flavours and clockable S&H circuit.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.
