Erica Synths Black OCTASOURCE is what we want to believe - an LFO carried to its extremes.


  • LFO with manually and CV controlled rate
  • Manual selection of phase shift direction
  • 8 simultaneous outputs
  • Synchronization to an external clock
  • LFO freeze function
  • 8 waves with morphing between them
  • Phase shift, wave select and FM CV
  • Bipolar output signal level LEDs

It features one of 8 waveforms available on 8 outputs phase shifted by 45 degrees OR all 8 waveforms simultaneously on all outputs. Furthermore, waveform selection, phase shift and LFO rate are CV controlled, and the rate can be synched to an external clock signal.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Erica Black OCTASOURCE on Modulargrid

Imagine this. It is a night. Very dark August night. You are taking a creative break and a little walk into the woods. Trees are huge, black and silent. No moon. You can’t see almost anything in front of you. You are alone. Just you and a massive darkness. 

Suddenly you run into something. It is a dog. Beautiful black dog lies across forest road. The dog is dead. You could take him home, but you can’t recall him to life. According to divine Masterplan he is supposed to be your best friend, however he is dead and out of any life signs now… 

Some call it the creative block. Buddhists call it corpse meditation. “We are obsessed with externals. No one wants to see the internals.” 

This is the point where Black Octasource steps in. 

The biggest mystery behind all the systems of modular synthesizers - you will necessary need The Source. An internal force to vitalize your armies of wonderful VCOs, VCFs, VCAs and your other friends, listeners among them. Without source for internal vibrations they are still half born, still hiding their wonders inside. You need to open them. With love, blood, sweat, water, fire and LFO.

Black Octasource or eight synchronized channels of creative energy is the power you were desperately missing to start a long and beautiful friendship with almost any of the modules you own.
