To clarify, the original files may be copied off the card and later returned to the recorder and the take containing them rebuilt, without any need to rename the files. This was not possible previously. The take could be rebuilt, but the files would only play sequentially as individual mono or stereo files, rather than all channels of the multichannel take playing simultaneously.
Alternately the files may be renamed before being returned to the machine for rebuilding and playback, as long as the naming scheme accommodates these Tascam file name requirements:
DR-680 file naming rules-
Mono file: XXX_monoY.wav
Stereo file: XXX_stY.wav
(XXX) = Take name part (no more than 10 half-width alphanumeric characters)
(mono) or (st) = file type
(Y) = Track number (1 to 6 for mono, 12, 34, or 56 for stereo)
file extension = .wav or .bwf
Just bought two more 32GB cards prior to a fest last a couple weeks ago due to this previous limitation. The last time I'll need to do that in the foreseeable future. Looking forward to updating and trying this out.
As a feature which was supposed to be there but was previously non-functional, his was long due for correction, so big thanks for this continued support for a now discontinued product, Tascam!
