No, the LFOs do not trigger notes. One LFO opens the amplifier and the other LFO defines the pitch that sounds.
If you want to trigger notes without Midi-In, you can use "Synth.playNote(NoteNumber, Velocity)". Note that you must also send a Note-Off command. This is then done with "Synth.noteOffByEventId()".
This allows you to trigger notes via script. David demonstrates this in his video, which is why I posted it. :-)
If you use this in combination with a timer, I think you can script an arpeggiator / sequencer.
