i seem to remember doing this before ... i think you have to right-click the presonus icon or something similar.

anyways, at the time, when i switched to high-cpu, i found that while getting lower latency, LIVE was unstable (i.e. it would just close, randomly) ... so, it didn't seem worth it.

I guess maybe it is a PC thing...I've never been able to adjust latency from within Live's audio preferences. That's one thing that annoys me about the Firebox....you can't just set the latency in samples, it's pre-calibrated for 2ms, 3ms, 4ms, etc.

I don't know how it works on a Mac....on PC there is the Firebox icon which you can click on to change the latency, sample rate, and mic preamp boost. If you right click on that icon you get a drop-down menu labelled CPU, with settings of High, Medium, and Low. According to Presonus, the High setting should be used with processors of 2 GHz and higher.

fair enough... that must be a pc thing then, i only do settings in the apps in samples, done. then there is the presonus mixer for routing and a control for input boost. that's all.

Hmm, well I've been testing it back and forth and the CPU setting doesn't seem to affect latency after all. I'm not sure what was going on....I wasn't able to get a decent latency seemingly until I switched that CPU setting, but now I can get acceptable latency. I have the Firebox set to 2ms latency (it's lowest setting) at 48kHz, and Live reports input latency as 96 samples / 3.63 ms / 9.13 total latency.

I don't think I would be able to detect 9.13 ms latency. I can only start to hear two sounds as distinct at around 20-30 ms, so it feels like the latency here is more like 20 ms rather than 9 ms. I'm playing guitar in and I can tell when I trem pick or play fast that there is noticeable latency...not enough to affect playing, but enough to get a weird disembodied feeling about it.

Still, it's definitely good enough to play...not quite like Neb's instantaneous RME setup though...
