 ## midiProgramChange for Arturia MIDI keyboards
-This is a MIDI CC to program change converter for Arturia MIDI keyboards.
-While their MIDI keyboards allow user configurations, it seems it is not possible to generate standard MIDI program changes.

+While their MIDI keyboards allow user configurations, it seems that it is not possible to generate standard MIDI program changes.
 
-This VST plug-in works with the Arturia default "Preset" knob configuration:
+You might be able to remap MIDI events in your VST Host (DAW), but as the "Preset" knob only sends relative changes, it is not so trivial.
+This VST plug-in maps the default Arturia MIDI CC commands of the "Preset" knob to MIDI program changes while keeping track of the absolute program number.
+
+How to use/operate:
   * rotating the "Preset" knob sends program changes instead
   * pressing down the "Preset" knob changes to the first program (reset)
   * all other MIDI events get passed thru
 
-No configuration needed, no GUI, just wire in your VST host this VST plug-in after the MIDI keyboard.

-(The expected MIDI CC ID for PresetEnc is 114, for PresetBtn the ID is 115. This is the default configuration on my Arturia Laboratory MIDI keyboard.)
