Tested the multitrack recording and I have longed for this feature for many years.
The only one thing that buggers me is this, the only "reference of sync/timeline"
is in the date and time of the file name.

An aditional file with "sync and timeline info" would be a warm welcome for anyone
wanting to sync the files together externally.

would only need to have a few lines of info:
