An inexpensive small, useful and versatile tool based on a Bill Sequeira's idea.

Features

• No power required
• Audio or CV passive summing (3 inputs, 1 output - mono or stereo) with attenuators
• Audio or CV passive splitting (1 input, 3 outputs - mono or stereo) with attenuators
  
• Fits banana sockets with horizontal or vertical mounting, including a ground one
  
• Fits mono and stereo Cliff minijack sockets. These sockets also accept tinijax.
• Fits mono and stereo 9mm pots
• Format jumbler
• LEDs showing activity on each channel (work with CV only)
• Plugs directly into the module's socket using a gender changer
• Concatenable

Due to the passive nature of the circuit, the incoming signals are slightly attenuated.
