Halo 4-Channel Complex Modulator

Vostok Instruments Halo

Bring the magic of analog modulation to your Eurorack system with Halo from Vostok Instruments, a compact four channel CV-controllable LFO with a dedicated logic output section. Each channel provides both manual and CV control over the LFO's frequency, along with a low and high switch for selecting between slower or faster oscillation ranges—with speeds from 80Hz all the way down to two minutes per cycle. Every channel comes equipped with individual outputs for both triangle and square waves, giving you access to additional modulation capabilities with each channel. Below the aforementioned outputs is a Logic Waveform Switch, which let's you define which of the two waveforms gets sent to the Logic Section of the module. This section offers AND, OR, XOR, and MIX logic outputs, divided into two sets of outputs split between channels 1/2, and 3/4. These logic outputs open up a world of potential modulations shapes with nearly endless possibilities depending on your chosen settings. If you're in need of a complex modulation source, Halo from Vostok Instruments packs an immense amount of power into a humble 10hp.
