  • Page 10 INPUT CHANNEL will be passed to the synth on the OUTPUT CHANNEL. For example, if INPUT CHAN is set to 1/2, and OUT CHAN is set to 3/4, note data received by MPG-70 on channel 1 would be transmitted to the synth on channel 3.
  • Page 11 DATA FI LTE R S : Different types of MIDI data chan be filtered by the MPG-70. When a data type is set to ON, that data type will be passed through the MPG-70. NOTE, CC data, AFTERTOUCH, and CLOCK/REALTIME data can be filtered. If PITCH BEND or SYSEX needs to be filtered, this can be toggled on the synth itself.
  • Page 12 Below is an example scheme for using Multi Unit Poly Mode. In this example Multi- Unit Poly Mode must be turned ON in the Global Settings menu. Playing notes into MPG-70 on MIDI PORT 1 on channel 1 will play the two MKS-70 units as a single 24-voice synth.
  • Page 13 C H O R D M O D E : The MPG-70 CHORD MODE function allows users to input a chord, and then play it by keying a note. The chord will be transposed anywhere on the keyboard where a new note is keyed. CHORD MODE can be enabled on UNIT 1, Unit 2, or BOTH units.
  • Page 14 MPG-70 and MKS-70 is required. This means that the MPG-70 MIDI OUT is routed to MKS-70 MIDI IN, and the MKS-70 MIDI OUT is routed to MPG-70 MIDI IN. When transferring a bank of patches from MPG-70, it should be understood that the format of PATCH objects in the MPG-70/JX is different than the format of PATCH objects in the MKS-70 memory.
  • Page 15 2. Use the Receive MKS-70 Patch Bank function in the MPG-70 Sysex Menu to load the bank into the MPG-70. 3. Use the Send Patch Bank function in the MPG-70 Sysex Menu to send the bank to the computer. (Once in the MPG-70, the bank has been converted into Retroaktiv Patch format) 4.

This allows us to do something like sweep the filter cutoff up on the UPPER layer, while sweeping the cutoff down on the LOWER layer. Using the assigns and combinations of assigns, a sound can be animated in ways not possible on other controllers.
  • Page 19 There are a few guidelines to follow to maximize the MIDI performance of the MPG-70 when using assigns. An ASSIGN has the potential to generate large amounts of MIDI data. If you’re using an ASSIGN with 5 layers, which is routed to BOTH layers of the synthesizer, this will generate 10 MIDI sysex messages with each movement of the ASSIGN source.
