Peter:

The early start doesn't happen only when you use an RT at a tempo SLOWER than which it was recorded.

I was just trying a song using style _T_FSHIN at 136 BPM and I added Resonator Guitar #613
(Guitar, Resonator, Background Hank Sw 130 ) recorded at 130 bpm.

On several generations of the song the resonator came in early. Not every time I generated the song-- but about half the time.
