Erica Synths | Black Classic System


Integrated modular system with functionality of classical two oscillator synthesizer and tons of cool features to address contemporary needs of modular users in Erica Synths skiff case.

The heart of the system is two Polivoks inspired Black Varishape VCOs. Unique waveform mixer, PWM circuit and most importantly transistor based suboscillators will bring you one of the fattest sounding VCOs you can get around.

Shape sounds with Black Polivoks VCF and Black VCA. Black Polivoks VCF has famous resonance screams in self-oscillation and can also be used as sine VCO. Versatile lin/log response VCA with CV bias control gives great tremolo effects.

Go further and add some crazy sounds! Black Digital Noise makes range of noise effects: from almost pure white noise to Atari console-like one bit noise and other more-less predictable noises. Its CV control over various parameters and clock sync feature give infinite explorations in non-musical sounds.

Black HADSR/AHDSR envelope generator has unique looping functions and CV control over each parameter and lin/log envelope option.

Tow LFOs with broad range of functions including 6 waveforms + S&H, TAP tempo, sync, start on GATE function and built in VCA with LFO amplitude hold/attack and decay function. Moreover, it can also be used as envelope generator.

Black Output module has manual and voltage control panning, balanced outputs and headphone amplifier.

Last but not least, very accurate monophonic/duphonic MIDI-CV interface which has analogue GLIDE, master TUNE, modulation CV, key velocity CV, CV IN (adds CV from midi controller to external CV for arpeggios).

Erica Synths Black series design looks mighty! We also paid attention to a layout making the system easy to play. Large knobs assigned to main functions of modules make it even more user friendly.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
