Description

Unleash your creativity with the Erica Synths Bassline Module, a Eurorack-compatible all-analog synthesizer voice that offers a rich spectrum of sounds perfect for both bass and lead applications. Designed for modular enthusiasts craving a complete voice in a single module, this unit packs a potent punch with its gritty AS3340 VCO featuring triangle, square, and sawtooth waveforms. Dive into a sonic playground with the transistor-based sub-oscillator and the resonant VCF inspired by the Erica Synths Acidbox, which offers both lowpass and bandpass modes for diverse tonal shaping.

The Bassline Module is equipped with dual bucket-brigade delay lines that emulate multi-voice detuning, delivering a lush, swarmlike effect reminiscent of detuned oscillators. With intuitive controls, including nine high-resolution knobs, you can finely tune parameters such as filter cutoff, resonance, and frequency modulation. The module also provides CV inputs for FM and VCF, enhancing its versatility in any modular setup.

The Erica Synths Bassline Module doesn’t just sound good; it's built for performance with tight 1V/octave tracking and an accent input that boosts volume and opens the filter when triggered. Whether you're crafting dirty synth sounds or creating distinct, throbbing basslines, this module is your gateway to audio experimentation.

    Source

User experience

  • There is confusion about different Erica Synths Bassline models, with some users mistaking the DIY version’s features for the commercial module.

Critic Reviews

Erica Synths Bassline

soundonsound.com

Erica Synths' Bassline Module offers a refreshing alternative to the typical TB-303 clone, with a unique acid pedigree. Its standout features include a versatile filter derived from the Erica Acidbox, and an oscillator based on the Curtis 3340 chip. While the module's pitch tracking can be finicky without careful calibration, it shines with its distinctive resonant qualities and a solid low-pass mode. The detune function adds rich textures, though can introduce noise at higher levels. Despite some limitations, especially in modulation flexibility, the Bassline's character and affordability make it a compelling choice for those seeking an original acidic flavor in their Eurorack setup.
