    The Binary is a direct clone of the Duality based on our own trace, which is documented at length in our tracing journal. Some extra power filtering has been added, but otherwise everything is true to the original.

    BUILD NOTES Filter and Blend knob rotation The Filter and Blend controls were inadvertently reversed in the original run of the Binary. This was fixed in version 1.1 which began shipping in January 2022. If your PCB does not say “v1.1” in the upper right then you have the earlier reversed version. In this version the blend knob goes from full effect at CCW to full clean at CW, and the filter control will act as a treble cut as you turn it up rather than adding treble as in a normal tone control.
