► Right-click  ([Ctrl]-click  on  macOS)  the  non-empty  Assignment  field  under  a  parameter
and select Unlearn in the menu to remove the MIDI assignment for that parameter.
→ The MIDI assignment is removed from the Assignment field and the parameter is not con-
trollable via MIDI anymore.
Of  course,  this  procedure  also  works  for  Native  Instruments  and  External  Plug-ins  loaded  in
MASCHINE.
11.2.4 Selecting VST/AU Plug-in Presets via MIDI Program Change
 
If you have a Native Instruments or third-party VST/AU plug-in loaded in a Sound, you can re-
motely  switch  presets  (or  patches,  programs,  etc.)  in  your  plug-in  via  MIDI  Program  Change
messages.
For this to work, your plug-in must expose its presets (or a particular set of presets) to the host.
Each VST/AU instrument or effect might handle its presets (or patches, programs…) different-
ly. Please refer to the plug-in documentation to know how to make its presets available to the
host.
For example, in MASSIVE, ABSYNTH 5, and FM8, you need to enable the Program List
and fill it up with the desired patches in order to expose these to MASCHINE and switch
between them via MIDI Program Change messages.
The Native Instruments or third-party VST/AU plug-in will listen to Program Change messages
according to the Source and Channel settings you have defined on the MIDI page of the Input
properties for the respective Sound — this page is described in detail in section ↑11.2.1, Trig-
gering Sounds via MIDI Notes above.
