My Aeros also falls out of time with my BB drums, but only on one or two songs - songs that it previously kept precisely in line with. Now it’s completely ceased to fire up when I hit the Beatbuddy, and it won’t complete the firmware update. After downloading it it says “Error code: 0. 1) Please insert a valid update file using the SD card 2) Unplug the Aeros power supply 3) Reconnect the Aeros power supply.” Unsure what they mean by step one’s “a valid update file using the SD card.” I’ve contacted Singular Sound and they say they’re contacting their “development team.”
