According to this link BWF files have a 4gb limitation.
http://www.ebu.ch/en/technical/trev/trev_274-chalmers.pdfThat would be one way to get around the 2gb limit. I am just curious about what settings people are recording to go over 2gb files. That is almost 2 hours at 24/48. are you doing 24/96 or just bands that play really long sets?
Not sure if that BWF file type upgrade is hardware related or something they could include in a firmware package for the version 1.
The solution to the brickwalling issue is a good upgrade.
The internal battery problem is easily defeated by the myriad of external power packs available. I ran into an old Nak 550 taper friend at a show the other night and he could not believe something this size has 1/4" jacks.
