I am running a Toshiba laptop with a Pentium 4, 2 gig, 3.4 Ghz with a
RME800 Firewire interface. Here are the latencies with different
48 samples 4.9ms
96 samples 6.9ms
128 samples 8.2ms
256 samples 13.5ms
I have been using the 128 sample/8.2ms setting lately.
Before I switch to the RME800, I used a Firepod and the latencies were
much greater -- in the order of hundreds of milliseconds. The driver
and chipset of the interface can have a profound impact on the
latency. That is, a "cheaper" interface may place more of the
processing burden on the driver side and, in turn, place more demands
on the laptop's CPU.
Before I started live looping, I never noticed the latency with the
Firepod -- Cubase compensates for it and I just happily worked with
multi-track recording, sequencing, etc. However, when I turned to the
laptop for live looping, the latency (and a few other issues)
surfaced. I have been extremely happy with the RME800.
