problem with phasing in a feedback loop

[bishbo2000]

I am having latency issues when setting up a delay feedback loop. its as if the send is adding a millisecond(s) of latency as the signal passes through, causing phasing and nasty frequencies

The feedback loop is simple, from a track in Ableton, not external, a ping pong delay and limiter (both Ableton effects) on the return and then sending back to itself

Also getting phasing when using third party compressor for parallel compression

Its the same with Delay compensation on and off,

it happens in a clean Ableton set also, 1 track of audio and 1 return, CPU at 4%

M-Audio Firewire 410 interface, buffer is 256 samples, no clicks or dropouts.

any ideas? does this happen to you too???
