Halo
Multi-Channel Complex Modulator
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 counts with 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.
