I just installed Amplitube CS. I've tried using it with an Xsonic Xtone and Line 6 HX Stomp as interfaces into my laptop. My laptop has 8 GB RAM and an i7 processor. I have plenty of drive space and the app has been installed to my primary drive.
I'm getting really bad crackling sounds when I play. It's not something that's happening every few seconds...as if I haven't authorized it...it's happening all the time. I can make it mostly go away by increasing the buffer to 1028 or 2056, but this causes massive latency.
I've used both the Xtone and HX Stomp as interfaces into my iPad and iPhone and I don't get the same crackling sound from Amplitube CS for iPhone or iPad. It's only occurring on my laptop.
I have updated all drivers and I still have the problem.
I just purchased iLoud Micro Monitors and I'm evaluating Amplitube 5 as a replacement for my HX Stomp. I'd really like to get the MAX version, but obviously I can't do that if I can't get CS to work.
