Module A-108 is a completely new voltage-controlled low pass pass filter based on the well-known transistor ladder (Moog ladder). The module has internally an 8 stage low pass filter with different slopes available: 6, 12, 18, 24, 30, 36, 42 and 48 dB per octave. In addition it features an band pass..
Module A-110-1 is a voltage-controlled oscillator. This VCO's frequency range is about eight octaves (ca. 15Hz ... 8kHz). It can produce four waveforms simultaneously: rectangle, sawtooth, triangle, and sine wave (triangle and sine shapes are not perfect, see remark below). The output levels are typ..
Module A-110-2 is a low-cost voltage-controlled oscillator. It's a slightly reduced version of the standard VCO A-110-1. Compared to the A-110-1 the A-110-2 has no sine output and the (expensive) octave rotary switch is replaced by a 3-position toggle switch. In return the A-110-2 is equipped w..
A-110-4 is a so-called Thru Zero Quadrature VCO. The term "quadrature" means in this connection that the oscillator outputs sine and cosine waveforms simultaneously. The term "Thru-Zero" means that even "negative" frequencies are generated. But this a bit a misleading term as negative frequencies do..
A-110-6 is a Trapezoid Thru Zero Quadrature VCO. The module is based on an idea by Donald Tillman from 2003 but has been revised for the use of modern electronic circuits (no OTAs/CA3280). Because of it's unique trapezoid core it's totally different compared to other VCOs. But the trapezoid cor..
Module A-111-2 is the successor of the obsolete High End VCO I A-111-1.Here are the most important features of the planned module:triangle coremin. 15 octaves pitch range (typ. 0.5Hz - 20kHz)perfect 1V/octave tracking over min. 10 octaves (typ. 20Hz - 20kHz)exponential frequency controls and in..
Module A-111-3 is an extremely space-saving precision VCO/LFO with a 4HP panel only. Essentially it's the same basic circuit as the A-111-2 but with reduced features:triangle corefully analog designmin. 15 octaves pitch range in each mode (VCO/LFO):VCO mode: typ. 0.5 Hz - 20 kHz ..
A-111-4 contains four precision VCOs and has individual controls, inputs and outputs for each VCO available as well as a common control and output unit. After all the A-111-4 is very similar to four A-111-3 without LFO mode but built in output mixers for the three waveforms, and a master u..
Module A-111-5 is a complete monophonic synthesizer module that includes these components (modular version of Dark Energy):VCOmanual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)range switch -1 / 0 / +1 octavefrequency range about 30Hz ..
Miniature Synth VoiceModule A-111-6 is a complete miniature monophonic synthesizer module that has these features available:VCOTune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)Oct.: range switch -1 / 0 / +1 octaveMod.: modulation de..
Module A-112 is the combination of a voltage controlled 8 Bit Sampler and a wavetable oscillator. On top of it the module is able to generate some special effects. A-112 was designed as an additional sound source with the typical sounds of the early 8 bit samplers and is not comparable with the mode..
Module A-113 is a new sound source that derives from an incoming pulse signal four so-called subharmonics (German: Subharmonische). The term subharmonics was introduced by Oskar Sala in connection with his so-called Mixtur-Trautonium. A subharmonic means in t..
