I went down that road beforet the new version was out. They cleverly called the timefactor twin delay because it doesn't have that option. the best responds i got was use the ping pong algorythm and play it in stereo.
What i REALLY RELLY want is a virtual limiter. I was disappointed that the new Beta ware had an boost/cut control instead of this. Thats fine with the Mod/Pitch-Factor but a Limiter is what the TimeFactor needs! I honestly haven't found any use for it on the TF :/
