Castor & Pollux II PLUS expander

Castor & Pollux is a dual oscillator that echoes back to the legendary Roland Juno but shines with its own unique, massive voice. It contains two digitally-controlled analog oscillators implemented using a faithfully modernized version of the original Juno 106 design. It builds on the classic ‘80s sounds of its inspiration by using the second oscillator and internal LFO to layer in thick detuned sounds and harmonically complex hard synced waveforms.

Castor & Pollux II brings a redesigned interface and moves individual waveform outputs to an included expansion module.

The heart of Castor & Pollux's pristine audio performance lies in its intricate analog circuitry, which demands an extraordinarily rigorous calibration. This isn't just a challenging build; it's a testament to highly skilled craftsmanship (thank you Winterbloom, and Thea). Alas, Winterbloom is no longer among us, and this module is out of OEM production.

This is a reproduction, as the original manufacturer Winterbloom has closed up shop and is no longer producing this module.
