Mixiplexer Interpolating Scanner - 12HP


Add plenty of flavor to your system with this unique signal routing device. Interpolate, scan, switch, crossfade, and more!

The Toppobrillo Mixiplexer or "mixing multiplexer", is a unique hybrid signal routing device that marries the idea and design of a quad-panner with a 4-channel crossfader, otherwise known as an "interpolating scanner"; a flexible 4-to-1 and/or 1-to-4 voltage-controllable "switch" with an adjustable linear cross-fade between channels.

Possible applications include source location or "position" control in a multi-channel setup, timbre mixing or "morphing" between sources, "soft" (ie. pop-free) switching, nonlinear wave-shaping techniques, and programming.

The Mixiplexer is all analog, and has been designed with audio in mind-(though is DC coupled) employing high quality low-noise VCAs throughout, with excellent channel separation and gain matching from channel to channel. "Off" is really "off" (-100dB) and "on" is never greater than unity gain.

Many combinations of input/output routing are possible, which allows for channel-to-channel routing, 1-to-4 or conversely, 4-to-1 or any combinations therein.


  • Four channel complex panning, scanning, and crossfading device
  • Continuously variable and voltage controllable crossfade response or "slope"
  • Four high quality linear VCA gain-control elements
  • Normalization scheme allows for easy 1 to 4 routing; patching into channel inputs breaks normals.
