“The DPO is a voltage controlled oscillator designed for generating complex waveforms and implementing FM synthesis within the analog domain. Expanding on the classic arrangement of Primary and Modulator Oscillators, the DPO has both of the VCOs operable as complex signal sources. It is in essence a Dual Primary Oscillator.” – ctrl-mod.com

“MATHS builds on the tradition set into motion in the 1960′s when Don Buchla adapted circuits found within analog computers for musical purposes. Buchla’s Algebraic Processor, Model 257 and 281 changed the way music synthesizers utilize control voltages. MATHS continues this great tradition of sculpting the control signals we use to sculpt our sound signals.” – makenoisemusic.com

“A Vactrol is an optoelectronic device consisting of a source and detector of light, which are optically coupled and electrically isolated from each other. The light source is usually a light-emitting diode (LED), a miniature incandescent lamp, or sometimes a neon lamp, whereas the detector is a semiconductor-based photoresistor made of cadmium selenide (CdSe) or cadmium sulfide (CdS). The source and detector are coupled through a transparent glue or through the air.” – Wikipedia

“The RXMS is a concept we are working on with Grant Richter. It stands for Richter’s Exquisite Mixer. The concept behind is a to apply the surrealist techniques of the exquisite corps game to patching.” – Tony Orlando (Make Noise)

“The only thing I am seeking at the moment is a unique reverb algorithm to design a Make Noise reverberation module around. Tom Erbe and I are currently chatting about that one.” – Metrono.me

“This podcast will hopefully illuminate the world of synthesizers and the people who use them along with the people who build them and repair them.” – Waveform City

“The so-called state-variable filter has a long history in electronic music- traditionally the most versatile voltage-controlled filter at any analog synthesist’s disposal. there were several classic design examples and variants produced throughout the heyday of analog synthesis, such as those implemented in the Oberheim SEM, the EDP Wasp, and the fabled,albeit lesser known filters such as the famous Serge filters and Arp 1047; the classic SVF configuration is simple and versatile- with several different filter responses available simultaneously ‘for free’ by nature of it’s design with no elaborate mixing schemes. traditionally there have been some considerations when designing a wide-range filter with variable Q using this topology, for instance, relative instability/ generally poor sound and behaviour at very high Q, many designs get around this by limiting the maximum Q available, among other things. those that are designed to allow for self-oscillation will often become unstable at the threshold and have inconsistencies initiating or mantaining oscillation across the entire audio range. The Toppobrillo Multifilter is a new/ traditional state-variable design based on a great modern quad VCA chip, the SSM2164. this, in part, helps make the Multiflter what it is, a clean, quiet, stable and very controllable filter at it’s core, without limiting its palette, well suited for processing anything you can run through it.” – toppobrillo.com

“CV/Gate (an abbreviation of Control Voltage/Gate) is an analog method of controlling synthesizers, drum machines and other similar equipment with external sequencers. The Control Voltage typically controls pitch and the Gate signal controls note on/off. This method was widely used in the epoch of analog modular synthesizers, beginning in the 1960s and up to the early 1980s. It was mostly superseded by the MIDI protocol, which is more feature-rich, easier to configure reliably, and more easily supports polyphony.” – wikipedia.org/wiki/Control_voltage
