Black Classic System


A fully integrated modular system with jam packed functionality by use of a classic two oscillator architecture with tons of awesome features to address the modern needs of synthesizer players is now available in Erica Synths Classic Black System.

The central core of the synthesizer is two Polivoks inspired Black Varishape VCOs. The special waveform mixer, pulse width modulation circuit and most importantly, the transistor based sub-oscillators will bring out one of the phattest sounding VCOs available. 

Shape the timbre of the sounds with the Black Polivoks VCF and the Black VCA. Black Polivoks VCF has iconic resonance screams when boosted into self-oscillation and in this state can also be used as sine VCO. Changing between lin/log response in the VCA with CV bias control provides precise control over tremolo effects.

Go further and add some more complex sounds! The Black Digital Noise makes a wide range of various  noise types: from almost white noise to Atari console-like videogame  one-bit noise and other more or less predictable noises. The CV control over almost all parameters, including clock sync, gives infinite explorations in timbral complexity and noise generation.

The Black HADSR/AHDSR envelope generator has classic looping functions that turn it into an LFO,  complete with CV control over each parameter and lin/log envelope shape option.

Included are two LFOs with a broad range of functions including 6 waveforms including S&H, a TAP tempo button, phase sync, and a start on GATE function with a built in VCA with LFO and hold/attack and decay envelope functionality.

Black Output module has manual and voltage controls for panning, with balanced outputs to patch into a PA, and headphone amplifier for more personal patching. 
Last but not least, a very accurate monophonic and duophonic MIDI-CV interface with analog GLIDE (portamento), master TUNE controls, modulation CV outputs, key velocity CV outputs, and CV IN (adds CV from midi controller to external CV for arpeggios) for transposition.

Erica Synths Black series design is mighty! Special attention was given to the layout of the system, designing it to be particularly easy to play. Large knobs are assigned to the main and most important functions of modules make it even more tactile and user friendly.
