Hey again, I know you are in contact with support but I don’t believe you sent your affected songs to us from your SD.
Please, if possible, connect your SD to the computer, copy the affected song folder from SD to computer.When doing this copy the folder not the contents, do not alter the contents or this could corrupt the song from being readable by the Aeros. Compress the song folders into a .zip or similar format and send to support@singularsound.com.
Something that would also be helpful to have from you is your log files after this happens to you. If possible, please activate the Active Logger and get the Aeros to have the exact same behavior. Then, please send the logs along with your songs to support as well!
Here is how to use the active logger as described in the manual:
Active Logger
This is a new logging system that is available starting with version 4.0.0. This logger records all events that the looper undergoes and is intended to help us diagnose issues that are hard to replicate. This system can only be used if there is an SD card inserted into the Aeros. To turn on the Active Logger go to the Updates Page, then to the Diagnostics Page. On the Diagnostics Page there is a toggle button at the top right of the page, turn this on to start the Active Logger.
If this feature is off, the Aeros’ logging system will work as it did previously: When an SD card is inserted, boot-up data as well as any data from a crash will be saved in a log file on the SD card. These events will also be logged when the Active Logger is on.
Note: This Logger does use some memory when active, due to this reason you may experience less than perfect audio quality when it is on. This Active Logger is by default off, only turn it on when trying to catch a bug that is hard to reproduce.
Important: Logs are not saved forever, a log will be saved from the previous power on, but if you turn the Aeros off and on again, that log will be lost. Only the current power cycle and previous power cycle logs are kept.
For now, I would create a new song (do not simply clear and reuse the same song) and use that. This song file may have something odd going on. Because I cannot verify if the other users reporting the exact same behaviors at this time, you are the only user reporting this specific behavior.
One question I’d ask is what type of SD do you use?
Thank you for your patience!
