7. P.L.tr Pitch LFO retrigger

Defines what should happen to the oscillator's pitch LFO ("Low Frequency Oscillator") when a new note is triggered;

• 'FrEE' will not cause the LFO to restart
• 'Retr' will cause the LFO to restart
• 'Cond' will only cause the LFO to engage if the step that triggered the note has a valid ('when') 'PLFO' condition ('do') set.
  
• on' will cause the LFO to restart
