Module A-101-1 is a special multitype filter based on an idea by Nyle A. Steiner (published in Electronic Design, issue  25, December 1974, page 96 ff). The circuit uses the standard non-inverting amplifier filter design. Different filter types (low pass / LP, band pass / BP, high pass / HP) ar..

A-149-2 is an extension module for A-149-1. It makes available 8 digital random voltages (i.e. only low/high states like a gate signal). The outputs are controlled by the "Quantized Random Voltages" section of the assigned A-149-1 and correspond to the 8 digital outputs of the shift register th..

Module A-149-1 is the first module of the A-149-x range. In this group we present by popular request several functions of Don Buchla's "Source of Uncertainty 265/266" (SOU) modules that cannot be realized with existing A-100 modules. Many functions of Buchla's 265 and 266 SOU can be realiz..

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..

Module A-146 (LFO 2) is a Low Frequency Oscillator, which produces periodic control voltages over a wide range of frequencies. The LFO can be used as a modulation source for a series of modules (for instance pulse width and/or frequency modulation of a VCO, modulation of a VCF cut-off frequency..

Module A-146 (LFO 2) is a Low Frequency Oscillator, which produces periodic control voltages over a wide range of frequencies. The LFO can be used as a modulation source for a series of modules (for instance pulse width and/or frequency modulation of a VCO, modulation of a VCF cut-off frequency..

Module A-145 is a low frequency oscillator, which produces cyclical control voltages in a very wide range of frequencies. Five waveforms are available: sawtooth, inverted sawtooth, triangle, sine and square wave.The LFO can be used as a modulation source for any number of modules - for instance modu..

Module A-143-9 is a derivative of our planned thru-zero quadrature VCO. It is a voltage controlled sine LFO with 4 outputs. The phase shift between the outputs is 90 degrees. The sine shifted by 90 degrees is also called cosine, the sine shifted by 180 degrees is nothing but the inverted sine, ..

Module A-143-4 is a fourfold voltage controlled low frequency oscillator (LFO). As the frequency range includes moderate audio frequencies it can be used as a four-fold VCO too.four independent VCLFOs/VCOs with triangle corefrequency range switches: low (bottom position) = LFO mode, high&n..

Module A-143-3 is a low-cost four-fold modulation oscillator, often called LFO (low frequency oscillator). Like the other modules of the A-143 series (A-143-1 andA-143-2) not a very "exciting" module, just a bread-and-butter device and a simple demon for work. The module contains four simple LF..

The A-143 series of modules contain multiple modulation sources. Module A-143-2 is a four-fold ADSR type envelope generator. Other modules of this series are the Complex Envelope Generator A-143-1 (Quad AD) and the Quad LFO A-143-3.The module contains 4 independent ADSR-type envelope ..

Overview: Module A-143-1 is a complex envelope generator that consists of Attack/Decay generators. For the complex envelope generator the four units are daisy-chained, i.e. the preceeding unit triggers the following unit. The four units can be used even as four separate AD generators (switch po..
