Description

The Erica Synths Black Octasource is a modular synthesizer marvel, designed to bring your Eurorack setup to life with its many-tentacled modulation capabilities. This all-analog LFO is the secret weapon for sound designers seeking to craft intricate, evolving textures and rhythms. With eight simultaneous outputs, the Black Octasource offers unparalleled flexibility in shaping your soundscape.

Whether you're syncing to an external clock or operating manually, this module shines with its dual-mode operation. In SINGLE mode, a single waveform is phase-shifted by 45 degrees across the outputs, while MULTI mode unleashes a different waveform on each output, morphing them seamlessly for dynamic sound transformations. The intuitive WAVE knob lets you manually or CV-control the waveshape, ensuring the right modulation for every creative need.

For the experimental musician, the Black Octasource includes CV inputs for WAVE, Phase, and LFO FM, granting you full control over its modulation prowess. The inclusion of features like the LFO freeze function and morphing capabilities further enhances its versatility, making it a staple in any modular setup.

Key Features:

  • All-analog low-frequency oscillator with manual and CV rate control
  • 8 simultaneous outputs with 8 available waveshapes
  • SINGLE mode: 45-degree phase shift across outputs
  • MULTI mode: different waveform on each output with morphing
  • WAVE knob for manual and CV-controllable waveshape morphing
  • Synchronization to an external clock
  • LFO freeze and morphing functions
  • Two-color output signal level LEDs
  • Power Usage: +82mA @ +12V, -44mA @ -12V
  • Module Width: 12HP, Depth: 25mm

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Erica Synths Black Octasource.

Features and functionality

  • The Erica Synths Black Octasource is noted for being a single, clock-syncable LFO with 8 phase outputs or 8 wave outputs, useful for ambient music.

    Source
  • Octasource offers eight simultaneous outputs and can be used as a low-frequency wavetable oscillator but lacks FM when synchronized.

    Source
  • Octasource's rate knob, when sync'd, limits users to specific speeds: 1/4x, 1/2x, 1x, 2x, 4x, and frozen, impacting modulation depth.

    Source

Comparisons

  • The Black Octasource creates repeating modulation with 45-degree phase shifts, while the DivKid Ochd provides 8 un-synced LFOs for non-repeating variations.

    Source
  • Compared to Ochd, Octasource provides more control but all outputs operate at the same rate, limiting its versatility for complex soundscapes.

    Source
  • Batumi, though more expensive, provides superior modulation capabilities and requires the Poti 2 for full functionality, unlike Octasource which is more self-contained.

    Source

Use cases and applications

  • For ambient music, Ochd’s unsynchronized LFOs are preferred for more organic, non-repeating sound layers compared to Octasource’s synchronized outputs.

    Source
  • For those looking for clock-synced modulation, Octasource offers precise phase-shifted outputs beneficial for structured ambient compositions.

    Source

User experience

  • Users exploring ambient soundscapes often consider modules like the Xaoc Batumi for tempo-synced independent LFOs, offering a balance between Octasource and Ochd features.

    Source
  • Owners note Octasource's synchronized outputs are limited to six fixed rates when sync'd, affecting its flexibility in dynamic modulation.
