The white noise issue was never an issue for me in particular. After reading about it here, quite a while back, I decided never to tempt fate, especially in a performance setting. I always use an iPod Touch for audio playback either connected directly to channels 15 & 16 in stereo, or through AirPlay. But the white noise problem should never have happened just the same, out of the gate. Thank goodness this issue disappeared with MF 3.x though. :thu
I have a sneaking suspicion that it’s not actually MF 3.x with the issues. I’m leaning towards a lack of processing power in the older iPads. I think Wynnd mentioned a while back that MF 3.x is a total re design from the ground up and quite possibly just requires more CPU / system RAM to run smoothly. And the older iPads cannot handle it. I may be just talking absolute poodoo here, but that’s my impression. I’m sure the more tech savvy members will be able to explain this better than I can.
It is quite interesting that there are quite different experiences on the same hardware/software to quote ijpengelly. I'd be interested to find out too.
