Rytm won't respond to MIDI data on Auto channel in Overbridge mode

A Logic Scripter script to translate incoming auto-channel notes on Ch14 (the default) to individual track channels on note C-1 (Midi 36) follows (this works as a workaround, but isn’t ideal):

/*
  Rytm translate auto-channel defaults into Note/C1
  channel equivalents (works only with default track
  channel settings)
*/

function HandleMIDI(event)
{
  const CHANNEL_AUTO = 14;
  const NOTE_C1 = 36;
  
  if(
  	(event instanceof NoteOn || event instanceof NoteOff) &&
    event.channel == CHANNEL_AUTO	
  )
  {
    event.channel = event.pitch + 1;
    event.pitch = NOTE_C1;
  }
  event.send();
}
