Okay, really desperate here, I would really appreciate some help as I've tried everything. Been trying to work out the presonus firepod for the last 3 months, but nothing worked. Here are the symptoms : 1) strange artifacts, noise and glitches are added to the recorded sound, kinda like a bit crusher effect used on the tracks. This glitch can be heard either on playback, or while I record on the phones output of the firepod. Imagine a distortion + pitch vibrato going on. 2) as I record, the tracks on Cubase don't "grow" as fast as the time cursor line, when I stop the recording, the tracks shrink, to various sizes. Here is what I have tried : - every possible combination of settings as for latency, drivers settings, etc. - installing a fresh windows on a new partition with sp2 (I had sp1 installed prior) - trying another firewire cable - trying the firepod on my mac laptop (that worked, but only tested once) Dunno what else to do !!!! HELP !! This is delaying all by projects. One thing kind of worked temporarily, when I change internal clock to S/PDIF and then back to normal, the recording will work for 1 or 2 minutes, then the bitcrusher comes back for no reason. On a side note (though this doesn't constitute a problem) on my old windows sp1, the pc would recognize my MOTU Ultralite but ask for sp2 to go through with the installation. On the fresh windows sp2 install, the pc just doesn't see it !?!?!? The computer is an AMD Athlon with 2 gigs of RAM. Recording goes on an another internal hard drive, using Cubase as a software, when I tried the firepod on my laptop, I used the same Cubase. Francis.
