In the RME website they have the latency tests, which go down until 3ms in some pc laptops (IBM, HP and some others). With powerbook it is 1.5ms. Is the latency in the other system better? (digiface or MADI-cards)
on MADI we had latencies go down to 4.5ms (if i remember correctly; probably it was a bit more like 6ms)
i do not think that fireface will really get low latencies with any dsp-software. of course you could utilize the "onboard" mixer to have the so-called "0 latency"-features of the card, but then you cannot do any processing of the data. this is kind of a marketing trick, as people tend to think that latency means ADC->FirefaceIN->PC->FirefaceOUT->DAC while it really is ADC->FirefaceIN->FirefaceOUT->DAC.
and then pd's structure imposes the 4.5ms latency, so you will never get as low as advertised.
