Description

Discover new sonic dimensions with the BASTL Instruments Aikido, a versatile addition to your modular synthesizer setup. This Quad VCA and mixer module offers an intuitive interface that invites experimentation with its four identical VCA channels, each equipped with level control, mute switch, CV input, and signal input/output. Designed for both creative and technical flexibility, the Aikido excels in dynamic sound shaping, making it a go-to choice for musicians who crave precision and expressiveness.

The Aikido goes beyond the ordinary with its side chain envelope follower, normalized to input A, providing three selectable response times for nuanced modulation. Whether crafting subtle textures or bold shifts, the spectral envelope follower, normalized to output D, offers three selectable frequency ranges, allowing you to capture and sculpt the perfect sound.

Ideal for both studio and live environments, the sum output and separate outputs for envelope followers expand your routing possibilities, giving you the power to create rich, layered soundscapes with ease. With its efficient power consumption of 120mA (+12V) / 120mA (-12V), the Aikido is a reliable workhorse that fits seamlessly into your Eurorack setup.

Key Features:

  • Quad VCA and mixer with four identical channels
  • Level control with 6dB gain and mute switch on each channel
  • CV input and signal input/output for each VCA channel
  • Side chain envelope follower normalized to input A with three response times
  • Spectral envelope follower normalized to output D with three frequency ranges
  • Sum output and separate outputs for envelope followers
  • Power consumption: 120mA (+12V) / 120mA (-12V)

Critic Reviews

Casper X Bastl - Aikido Review | More than a VCA Module — SINESQUARES

sinesquares.net

Bastl Instruments' Aikido isn't just another VCA module; it's a multifaceted powerhouse that elevates any Eurorack system. With its quad VCA and mixer capabilities, plus unique features like Mute buttons and Sidechain options, it stands out in a crowded market. The module's build quality and intuitive layout make it a joy to use, whether you're performing or patching in the studio. While its 11 HP size might irk those with OCD for even numbers, the Aikido's depth and versatility more than justify its slightly higher price tag compared to simpler VCAs.

Bastl Instruments reveal Aikido

soundonsound.com

Bastl Instruments' Aikido Eurorack module offers an intriguing blend of functionality with its quad VCA mixer and dual envelope followers. Its promise of flexible sub-mix and modulation routing, alongside instant side-chain compression, makes it a versatile tool for sonic experimentation. The clickless mute switches and dedicated level faders for each VCA are a nice touch, adding usability points. However, the module's complexity might be overwhelming for beginners, and its reliance on internal normalling could limit customization for seasoned users. At €245, it's priced reasonably for its feature set but may not be the best fit for everyone.
