The beloved Auxiliary Oscillator Card for the Buchla Music Easel is back — redesigned, more affordable, and more powerful than ever.

This expansion brings a whole new dimension to your Easel by adding a digital oscillator that covers everything from slow modulation rates all the way up to audio frequencies. Alongside it, you’ll find a dedicated noise source with its own filter, giving you instant access to textures ranging from subtle grit to full-spectrum noise.

To shape your sound even further, the card includes CV control over the balance between oscillator and noise, making it easy to create evolving timbres and dynamic modulation. A set of intuitive switches provides quick routing options. On top of that, the redesigned card introduces a CV Multiplier allowing to merge two control voltages.

And with full compatibility across all Music Easels and Easel Commands produced after 2012, it integrates seamlessly into both modern and retro systems.
