    • Description:
    • The Yamaha MEP-4 is a Midi Event Processor, accepting incoming midi data and modifying it to the midi outputs. Four micro processors are included, allowing very flexible midi operation. Examples of use would be: split a single keyboard in four ways, independently transposed, midi echo, on a different note and sound, connect a drum machine to the MEP4 and play the kick drum with your sustain pedal, accent only strongly played notes with another tone generator, set aftertouch to send pitch bend messages, etc.

      Other features include:
      * up to 60 patches can be programmed - even a 9 character name can be assigned
      * data presetter functions for patch change of connected instruments at once
      * channel filtering
      * message filter
      * data modifier (as in examples above + much more)
      * delay processor (echo from 0 - 3000 ms, more)
      * output assigner
      * 1 midi in/4 outs + 1 thru
      * 16 character backlit LCD.

      The Yamaha MEP-4 is a MIDI Event Processor, accepting incoming MIDI data and modifying it to the MIDI outputs. Four micro processors are included, allowing very flexible MIDI operation.

      The MEP-4 is a totally new type of device that gives you complete control over MIDI signals. You can use it to change, ignore, filter and delay any type or types of MIDI signals.

      Examples of use include:

      * Double-tracking: By setting the MEP-4 to send a slightly delayed duplicate Note On signal for each one it receives, you can get the sound of 2 instruments played in unison. You can also set the delayed note to be sent on a different MIDI channel, which will give you 2 different instruments in unison.

      * Echo: You can delay the MEP-4 output, which will give you an echo effect. You can set the MEP-4 to send out a note (or notes) a set interval higher or lower than the note it receives, producing an echo of a different note.

      * Keyboard split: Using the MEP-4, you can split any MIDI keyboard into up to 4 sections (overlapping sections if you wish), and send Note On messages on a different MIDI channel from each section.
      The keyboard can be split in four ways, with each independently transposed.

      * Turn your MIDI keyboard into a MIDI master controller: You can set the MEP-4 to change incoming Modulation Wheel messages into outgoing Portamento Time messages. Or change Data Entry +1/-1 messages into Mono On/Poly On messages.

      * Increase or decrease Aftertouch or velocity sensitivity: Do you play with a heavy hand? Set the MEP-4 to cut in half (or a quarter or an eighth) all Aftertouch or Velocity Information. Or do the same with the Pitch Bend Wheel or Breath Controller.

      * Accent notes with another sound: Set the MEP-4 to send an additional Note On message to a different tone generator whenever you play a note especially strongly.

      * Connect a drum machine to the MEP-4 and play the kick drum with your sustain pedal.

      * Set aftertouch to send pitch bend messages, etc.

      The uses mentioned above show just a small fraction of the MEP-4's possibilities. The MEP-4 will multiply the flexibility and power of any MIDI keyboard setup. Also very useful with breath controllers.
