Really? I don't think so. The latency setting you select in the setup menu is not the TOTAL latency, the 4ms you selected is the In/Out latency of the Audio 8 soundcard. So that 4 ms In + 4ms out = 8ms, then you have to add the timecode decoding/processing latency, which is where the rest of it comes from. Total latency = In + timecode process + Out.Latency is 4ms btw, not 20 like someone here mentioned
Depends on if you're using a Mac or PC. Macs have more In/Out latency choices to choose from than PCs. I only test on my Macbook at the lowest setting (1.5ms) and 44.1kHz. The lowest needle drop latency I could get was 14-16ms (avg 15ms) But needle drop latency isn't as good to measure total latency compared to change of velocity measurements. If you really want to know to do that, read this...

Or you can just check nem0nic's page ( http://www.nem0nic.com ), he's a beta tester for TS and has done test as well, but only on PC he's only done needle drop latency, which he found to be 13ms.
I take it you mean the multi-colored waveforms. Well, they are not just random colors. They actually mean something and are frequency based color coded. Red = bass, green = mids, blue = highs. I HATE the TS interface. Mono-colored side by side waveforms? Sorry, SSL's stacked (vertical or horizontal) and colored waveforms are much better IMO. But who cares, stuff like GUI and waveform colors are subjective and a matter of personal preference.but I HATE the Serato interface, it's like someone ate magic fluo markers and barfed over your screen
