Vostok Instruments Halo Eurorack Multi-Channel LFO Module

We say...

Another winner from Vostok - this time a quad LFO with a built-in logic section for maximum modulation!

Manufacturer's description

Halo is a compact quad LFO designed to provide a large amount of modulation in 10HP. The module generates up to 16 simultaneous signals covering a wide range from classic triangle and square waves to complex logic-based sources.

Each channel is built on a CV-controlled analog core and offers two selectable frequency ranges, finely tuned to cover most applications. The Logic section creates new waveforms from each channel pair using analog boolean circuits for AND, OR, and XOR operations, as well as a mix of both channels.

Halo has the classic Vostok design layout, making it friendly and accessible to any user, yet also deep and powerful in functionality, allowing you to create an entire array of modulation goodness in a compact form.

Features

• Four analog CV-controlled LFOs.
• Manual and CV-controlled frequency per channel.

• Selectable frequency range from >2min to 80Hz.
• Dedicated Logic section adding 8 extra modulation outputs with AND, OR, XOR, and MIX operations for each pair of channels.
• 16 simultaneous modulation outputs covering a wide span of complexity in 10HP.
