    VCO – Voltage Controlled Oscillator, a continuous voltage source, which will output a signal whose frequency is a function of the settings. In its basic form these may be simple waveforms (most usually a square wave or a sawtooth wave, but also includes pulse, triangle and sine waves), however these can be dynamically changed through such controls as sync, frequency modulation, and self-modulation.
    Noise source - A source that outputs a random voltage. Common types of noise offered by modular synthesizers include white, pink, and low frequency noise.
    LFO - A Low Frequency Oscillator may or may not be voltage-controlled. It may be operated with a period anywhere from a fortieth of a second to several minutes. It is generally used as a control voltage for another module. For example, modulating a VCO will produce frequency modulation, and may create vibrato, while modulating a VCA will produce amplitude modulation, and may create tremolo, depending on the control frequency. The rectangular wave can be used as a logic / timing / trigger function.
    EG - An envelope generator is a transient voltage source. A trigger in the presence of a gate, applied to an Envelope Generator produces a single, shaped voltage. Often configured as ADSR (Attack, Decay, Sustain, Release) it provides a transient voltage that rises and falls. It can be triggered by a keyboard or by another module in the system that produces a rapidly rising trigger in the presence of a gate. Usually it controls the amplitude of a VCA or the center frequency of a VCF, but the patchable structure of the synthesizer makes it possible to use the envelope generator to modulate other parameters such as the frequency or pulse width of the VCO. Simpler EGs (AD or AR) or more complex (DADSR—Delay, Attack, Decay, Sustain, Release) are sometimes available.

Processors - characterized by a signal input and an output; it may have control inputs.

    VCF - Voltage Controlled Filter, which attenuates frequencies below (high-pass), above (low-pass) or both below and above (band-pass) a certain frequency. VCFs can also be configured to provide band-reject (notch), whereby the high and low frequencies remain while the middle frequencies are removed. Most VCFs have variable resonance, sometimes voltage-controlled.
    VCA - Voltage Controlled Amplifier, is usually a unity-gain amplifier which varies the amplitude of a signal in response to an applied control voltage. The response curve may be linear or exponential. Also called a two-quadrant multiplier.
    RM - Ring modulator - Two audio inputs are utilized to create sum and difference frequencies while suppressing the original signals. Also called a four-quadrant multiplier or balanced modulator.
    Mixer - a module that adds voltages.
    Slew limiter - is a very-low frequency lowpass filter which slows down changes in voltage. This can be used to create glide or portamento between notes.
    S&H - Sample and hold, is usually used as a control-voltage processor. Depending upon the design, usually an ascending edge (trigger), captures the value of the voltage at the input, and outputs this voltage until the trigger input reads another voltage and repeats the process.
    Sequencer, is a compound module which produces a sequence of voltages, usually set by adjusting values on front panel knobs. Basic sequencers will be stepped by a trigger being applied to the trigger input. More complex designs may have the sequencer step forwards or backwards, or only run for a limited number of stages.
    Custom Control Inputs - It is possible to connect any kind of voltage to a modular synthesizer as long as it remains in the usable voltage range of the instrument, usually -15V to +15V.

A little multi demo of my first (very minimal)2-osc  Doepfer modular. Well, Doepfer except the second oscillator which is a Tiptop Z3000 MkII (not installed on the picture)

Arp Sequencer

This track is a brief demo of some longer sequencer workout I created on New Year's Day 2015. Basically, it is two Oberheim SEMs controlled by two ARP Sequencers, multitracked onto eight-track using a clicktrack and a Friendchip SRC Synchronizer for overdubbing. The eight tracks were mixed down to stereo while additional sequencers were also tied into the mix. Apart from some delay,  reverb, and Dimension D simulation (Roland 330 series), no effects were added. The ratcheting was also done using two ARP Sequencers in conjunction.

I can't help thinking what a beautiful-sounding and extremely useful little synthesiser the Oberheim SEM is -- hats off to Tom Oberheim!

The Deviants are stoked to announce their 7th release- which is nothing less than the debut album of YaraKaviam: Experiment !

This full length 9 track masterpiece is brought to you by the fusion of the two creative minds, Yara and Malkaviam, who spent excessive working hours in the laboratory, analyzing and researching the effect of modulated soundwaves on the human mind.
The groundbreaking audio-outcome of their studies is showcasing perfectly the unique signature sound the duo developed over the years.
The whole album is defined through heavy basses &kicks, underlined by deep atmospheres blending together with mesmerizing layers of sound, all trickily arranged and produced on a high quality level.

User Advice: To maximize the intended effects, we recommend listening on high volume during late night-hours!
