JMK Music Pedals has introduced the Plexus:4, a MIDI Router & Filter capable of processing MIDI signals on a 4×4 matrix.

The Plexus:4 lets you Route, Split, Merge, Poly Chain, Filter, Clock Divide, Channel Map and Keyboard Split in a small stand-alone box, that you can configure and use without a computer. You can also create custom MIDI configurations on the Plexus:4 and save them as presets, with the ability to save up to 128 presets in memory.

Features:

• 4×4 MIDI Routing – Split and Merge each input with each output. The 4×4 Matrix of lighted buttons give clear indication of what messages are going where.
• Filtering – Block and modify MIDI Messages on each output independently. Can be used like Four stand-alone filter boxes. No computer is required to configure.
• Poly Chain – Incoming notes can be distributed, round-robin, to different outputs. Use several monophonic synths as one polyphonic synth.
• Keyboard Split – Send notes to different synths based on the pitch or the velocity of the note played. Easily divide notes from a keyboard up into zones.
• Clock Division – Divide an incoming MIDI Clock to create slower tempos. Seven divisions settings are available for each output independently.
• Status Monitoring – Each active button on the 4×4 Matrix will light different colors for incoming messages indicating that a message is being passed, modified or blocked.
