hmmm… i just got the TimeFactor and i still don't understand it. becuase what everyone has been describing is spill mode type of effect. I have mine's off so no matter what setting the XF is on the changes are always abrupt from presets. i WAS hoping it would be feeding the sound from delayA to delayB and visa versa but that's definitely not it. Why hasn't a staff member answered this yet?
