hi list lately i switched on presonus firebox audio interface i am concerned about the latency managed to reach 12ms in PD with the help of jack osx but read elsewhere that it is possible to get down to something like 4-5ms does anyone use the same configuration? what are your results? i am doing live vocal looping with overdubs so every ms of latency matters i`m on 1,5ghz g4 powerbook 1gb ram, osx 10.4 thanks for any repilies ma.
