SetonixSynth

Notes: SetonixSynth's Laka is a powerful, multi-functional and extraordinarily flexible hub for flipping, offsetting, combining, and re-routing voltage signals throughout a Eurorack modular system of any size. Equally at home manipulating audio or control voltages, Laka will quickly make itself at home in the thick of each and every patch, with its uses limited mostly by imagination.

Each of Laka's four channels offers a separate high-headroom bi-polar CV processor (also known as an attenuverter) with its own offset, perfect for "dialling in" a signal for optimal use with other modules. Each channel offers a high degree of control including a "Zero" switch and bi-colour LED indicator. The "solo" output of each channel is available at all times via its own output jack, but the channels are also available in various mixtures via the three Submix outputs (A+B, B+C, C+D) and main Mix output (A+B+C+D).

The four Channel outputs are also combined in a more novel way via the Sequential section. The right side of the module is dedicated to selecting one of the four Channel outputs and routing it to the Sequential output. This section is controlled by a high-quality manual pushbutton, a Clock input capable of operating at audio rates, a Reset logic input, and a switch controlling the number of steps. This section allows a user to create complex CV waveforms from the four Channels, flip through audio, "audition" new sounds or signals, and numerous other functions.

Voltage processing just got a lot more fun: Laka is here!

Notes: 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.

Notes: The SetonixSynth SkyWave is an all-analogue voltage controlled oscillator capable of producing many different timbres and unique harmonic behaviours, thanks to an original step-based control scheme which allows the user to dial in completely different wave-shapes and levels for successive oscillator cycles.

This complex VCO uses an internal feedback loop with the clock output of the oscillator triggering a step sequencer which in turn cycles through settings at the frequency of the core oscillator, thus changing the shape and level of the waveform output on a per-cycle basis while also staying in tune and tracking pitch like a typical VCO.
