Casper and Bastl released Aikido

Casper and Bastl released Aikido, a performative quad VCA mixer with flexible submix routing and two styles of integrated envelope followers. Clever normalization allows ready-to-go sidechain compression, expansion, and rapid routing experimentation.

Clickless mute switches and level faders make for immediate performability, while dedicated attenuverters on each channel make Aikido a powerful and flexible quad VCA. The main mix output is accompanied by individual VCA outputs with patch-programmable cascading mix routing. The Side Chain envelope follower offers 3 different response curves, while the Spectral Follower can be set to focus on treble, mid or bass frequencies.


  • 4 VCA channels, each with:
    clickless mute with light indication
    level fader with 6dB boost
    CV input with attenuverter
    input (DC coupled)
    output (DC coupled) cascaded mixing
  • Mix output (AC coupled)
  • Side chain envelope follower
    input (normalized to A input)
    output (normalized to CV inputs)
    switch to select response time
  • Spectral envelope follower
    input taken from Channel D output
    patchable output
    switch to focus the follower to low, mid, or high frequencies
  • Backside jumpers
    select whether direct VCA outputs are pre/post Mute
    cascaded mixing input and output (joins 2 Aikidos to 8 channel mixer)
    main mix input and output (for chaining the normalized MIX outputs), chainable with BUDDY
