That would have been my measurement.
The time from hitting a button to the time a sample starts to play.
To get down to 3-4mS you need a Gorduis Midi controller.
The fcb1010, and oddly enough the EDP front panel take 4-5mS.

Matthias says the EDP has 1mS jitter in response time, ie
it checks for button presses once a mS.

Any latency from the A/D converter got missed out in that measurement.

Triggering a sample by foot is a good way to learn to compensate
for brain>>foot>>sound latency, brain>>foot being by far the largest 
part of that.



andy butler 
anyone have figures for looperlative latency?
No reason to think it won't be comparably low, but increasing
sophistication can allow latency to creep up (as Xavier(LG) found out, and 
fixed),
and apparently A/D & D/A converters can get slower as the quality goes up.
