Oscillators

OVERVIEWDual oscillator following the west coast philosophy of one main oscillator with it's frequency or amplitude being affected by an modulation oscillator. Furthermore the main oscillator has athree wave shapers for altering timbre and for emphasizing certain harmonics. The internal modulation i..

OVERVIEWAnalog additive oscillator module that generates the first eight harmonic as sine waves. The frequency spectrum can be processed in a creative way by 3 CV inputs. Linear FM, a voltage controlled signal mixer with faders and three outputs for standard wave forms are available as well. The osc..

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-143-9 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-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 ..
