  • Page 3: Oled Display

    (PEEK mode) Buttons MPG-7 has 2 MIDI ports: Port 1 is a 5-pin DIN port, that have a second function will be labeled in blue and USB is a USB C port. MIDI data can be sent or underneath the button.
  • Page 4 POWE R I N G TH E M PG -7 MPG-7 can be powered by USB bus or by a 6VDC - 9VDC, 2.1mm x 5.5mm, center-pin positive, wall adapter. The USB port will still receive and transmit data when the unit is being powered by a wall adapter.

To return to the MAIN screen at any time, press the [MAIN] button in the navigation console. Pressing MAIN repeatedly will cycle between editing the Unit1, Unit2, or BOTH synths.

  • Page 7 7, you will see 3 channels displayed. This is because the MKS-7 has 3 layers (Bass, Chord, Melody), each of which must be on its own MIDI channel. For example, if set to 1 (2) (3), the MPG-7 will receive note and controller data on channels 1, 2, and 3, and will pass those messages to the MIDI OUT on the corresponding MIDI OUT channels.
  • Page 8 MPG-7 passes incoming note data to the synth. AUTO MODE: In auto mode, the MPG-7 listens for valid note data on the “base channel” (If set to receive on channels 1 (2) (3), then the base channel would be 1). Notes received on the base channel will be passed to the synth based on which layer is currently being edited on the MPG-7 (BASS, MELODY, or CHORD).

  • Page 10 MULTI-UNIT POLY MODE MPG-7 has the unique ability to turn 2 of any synth (Including synths that aren’t Juno-106 or MKS-7) into a single synth with double the polyphony. This can be used to turn 2 MKS-7/J-106 synths into a single 12-voice synth.
  • Page 11: Program Change Mode

    CHORD MODE On the MPG-7, Chord Mode allows you to play chords with a single keypress, and it works by “memorizing” a chord shape that you define and then applying it to every subsequent note you play. Chord mode can be applied to one or both synth layers.

    EDITING THE SYNTH When the MIDI settings are configured, the synth can be edited from the front panel of the MPG-7. If edit- ing a Juno 106, the EDIT SELECT buttons on the front panel will not be used. If editing an MKS-7 synthesizer, the EDIT SELECT buttons are used to indicate the current layer being edited.

INIT PATCH INIT PATCH To generate an “init patch”, press [SHIFT] + [PATCHGEN] buttons. This will transmit the default tone on the currently selected synth layer.
  • Page 14: Memory And Storage

    MPG-7 has onboard storage, allowing you to save your presets and setups. This is a much needed feature for the MKS-7, which doesn’t allow presets to be saved at all. MPG-7 comes with 128 KB of storage space, expandable to 256 KB with the optional plug in memory card.

  • Page 17 One major issue with the J-106 and MKS-7 is that they do not support MIDI bulk dumps, which makes loading a new bank of sounds tedious. MPG-7 allows users to import and export their banks using sysex bulk dumps, making it simple to transfer sounds and back up their data.
  • Page 18 MPG-7. layer of either synth plugged into the MPG-7. This allows us to do something like sweep the filter cutoff up on the one layer, while sweeping the cutoff down on another layer. Using the assigns and combinations of assigns, a sound can be animated in ways not possible with other controllers.
  • Page 19 There are a few guidelines to follow to maximize the MIDI performance of the MPG-7 when using assigns. An ASSIGN has the potential to generate large amounts of MIDI data. If you’re using an ASSIGN with 3 layers, which is routed to BOTH units, this will generate 6 MIDI sysex messages with each movement of the ASSIGN source.
  • Page 20 PATCH GENERATOR “VARIATION” FUNCTION PATCH GENERATOR “VARIATION” FUNCTION The MPG-7 patch generator contains many algorithms and makes several “choices” when generating a new sound. Sometimes the patch generator will generate a great sound, which we find ourselves wishing we could hear more variatons of. If the patch generator makes a sound that you want to hear variations on,...
  • Page 21: Weight And Dimensions

    WEIGHT AND DIMENSIONS The MPG-7 is 7 pounds and the enclosure measures 13” x 4” x 3”. The enclosure has 4 heavy-duty screw-on rubber feet for no-slip tabletop use.
