The Shaka-8 Eurorack module uses high-quality stereo VCAs with all-analogue signal paths to create a powerful, intuitive, and performance-ready solution for routing audio between stereo (or mono) oscillators, samplers, effects and more.

The Shaka-8 operates in much the same way as a typical stereo audio matrix mixer, with the send level of each input to each output controlled by the corresponding knob, and the resulting "mix" being a sum of the knob settings in each column, added to the CV input corresponding to each knob.

Even better, you can easily chain Shaka-4 expanders to a main Shaka-8 unit to create matrices of 4x3, 4x4, or even more! Each channel has the same high quality signal path as the main unit. Now you can send stereo audio to all the effects you like!

Some patch ideas

Basic Effects Send / Return: Patch an Audio Output channel to the Audio Input of an effect such as a delay or reverb, and patch the fully Wet output of the effect to an Audio Input of the Shaka-8. Patch up to three audio signals to the other inputs of the Shaka-8. Use the knobs and CV inputs for each audio signal to control the send level to the effect, and use the knob and CV input between the effects module's input and output to control feedback amount.

Parallel filtering: Patch a stereo filter in an "effects loop" style as detailed in the previous patch idea. Turn up the resonance or use feedback to create interesting spectral content related to the main audio inputs.

Stereo Amplitude Modulation: Patch a stereo audio signal to an input audio channel and feed a simple audio-rate oscillator waveform to the CV input, then monitor the output. Adjust the Initial knob to offset the CV signal for best response.
