6. A.L.tr Amplitude LFO trigger
Defines what should happen to the oscillator's amplitude 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') 'ALFO' condition ('do') set.
