I made my first two recordings this weekend using two A10s (one SBD, one AUD), and not only did bluetooth control work seamlessly, but I was amazed get home and find that the two clocks seem to have been in perfect sync — I didn't need to do any time stretching to line them up in Audacity.
Anyone else know if this is an unreported feature, or if I just got super-lucky with my two devices?
