What Robert is looking for is an effect like tape speed change, or delay 
time change on old delays, where changing the speed *does* change the 
pitch. Among Loopers, that effect has always been see as a good and 
desireable thing, while among remix artists it is apparently a bad thing. 
(I assume that is why the repeater doesn't work that way?)

So no, the repeater does not do the tape speed slow down effect. Speed and 
pitch change are independent. You could probably rig up a midi continuous 
controller setup where two midi cc messages were sent at the same time to 
control both pitch and time. (I haven't tried this, so I don't know if it 
works or how much it sounds like a real slow-down effect.)  With real tape 
speed or delay time slow downs you don't get artifacts in the audio. with 
sustained sounds in the repeater, you get artifacts when you time stretc. 
I 
have experienced that with long sustained chords the speed correction 
causes artifacts after 5-10BPM of change. Some of you probably want those 
artifacts, so it is good I guess. If you weren't expecting it, you'll 
probably find it annoying.
