External Devices

Using MIDI CC & SysEx

To modulate an external hardware device, such as a synthesizer, via MIDI CC or MIDI SysEx, please follow the steps described in this section.

  1. Create a "Software Instrument" track and add the External Instrument plug-in within the I/O section of the track. Select your predefined external synth, or configure a new MIDI device according to your setup (MIDI port and channel).
  2. Create a second "Software Instrument" track and add the Modulation Processor as a MIDI-controlled Effect within the I/O section of this track.
  3. Open the MIDI Environment (Window > Open MIDI Environment) and add a connection from the synth track to the MP3244 track (Note: you might first need to enable the "Advanced Settings" to "Open MIDI Environment": Logic Pro X > Preferences > Advanced Tools > Enable All). All MIDI notes on the synth track will now also be sent to the MP3244 track. This is needed to trigger the Slope and Envelope Generators. For special note triggering you can skip the connection.
  4. Set the MP3244 output options.
    • MIDI CC:
      as "Format" select MIDI CC, set the "Device" to the MIDI port where the synth is connected to and than set the "Channel" to which the synth is configured.
    • MIDI SysEx:
      as "Format" simply select "MIDI SysEx".

Using Audio CV

To modulate an external hardware device, such as a synthesizer, via Control Voltages, please follow the steps described in this section.

In AUDIO CV mode the plug-in functions as a multi-channel plug-in with following configurations:

  • Main Out: No output
  • Output 1 L/R = VCA 1
  • Output 2 L/R = VCA 2
  • Output 3 L/R = VCA 3
  • Output 4 L/R = VCA 4

  1. Create a "Software Instrument" track and add the External Instrument plug-in within the I/O section of the track. Select your predefined external synth, or configure a new MIDI device according to your setup (MIDI port and channel).
  2. Create a second "Software Instrument" track and add the Modulation Processor as a MIDI-controlled Effect within the I/O section of this track with "Multi-Output (1xStereo, 4xMono)".
  3. Open the MIDI Environment (Window > Open MIDI Environment) and add a connection from the synth track to the MP3244 track (Note: you might first need to enable the "Advanced Settings" to "Open MIDI Environment": Logic Pro X > Preferences > Advanced Tools > Enable All). All MIDI notes on the synth track will now also be sent to the MP3244 track. This is needed to trigger the Slope and Envelope Generators. For special note triggering you can skip the connection.
  4. Open the Mixer Window and add 4 additional AUX channels by clicking the "+" icon on the MP3244 channel.
  5. Select for each AUX channel a physical output of your audio interface to which the CV data will be sent.
  6. Done!

Internal Devices

To modulate a software device, such as a synthesizer, within Logic, please follow the steps described in this section.

In-Host MIDI CC

In order to get this working you need system wide virtual MIDI buses. Mac OS provides a built in IAC Driver that lets you create virtual MIDI busses. For further information please refer to the Virtual MIDI Guide.

  1. Create a new Software Instrument track for your virtual synth and add your virtual synth within the I/O section.
  2. Create a second Software Instrument track and add the MP3244 as a MIDI-controlled Effect within the I/O section of this track.
  3. Set the MP3244 OUTPUT to MIDI CC and choose one of the IAC Driver Buses as DEVICE. Select the MIDI channel you want to send the data.
  4. Open the Environment and add a connection from the synth track to the MP3244 track. All MIDI notes on the synth track will now also be sent to the MP3244 track. This is needed to trigger the Slope and Envelope Generators. For special note triggering you can skip the connection and trigger the MP3244 directly from the track.
  5. Within the Environment add a physical input (New > Physical Input). Than connect the IAC Driver Bus (selected on the MP3244) to the synth track.
  6. Within VCA1 select the Continuous Controller number you want to send. If your virtual synth has a MIDI learn function you can choose any number.

    A: MIDI learn function
    This only applies if your virtual synth has a MIDI learn function: enable MIDI learn and click on the desired parameter. Go to the MP3244 and “twittle” the VCA1 GAIN knob. The synth should now receive the CC messages. As soon you are finished, turn the MIDI learn function off.

    B: No MIDI learn function
    If your synth does not provide any MIDI learn function you need to grab the synth manual and see if and what MIDI CCs are available. To modulate the CC you need to select the specific CC number within the VCA1 of the MP3244.
  7. You are all set!
