2EH is a song converter, it uses all the loaders except
UltraTracker, Extreme Tracker and Imago Orpheus (because they use
multiple commands, which EH does not support).

Not ALL commands in the supported formats are... supported, so
if a FNK song uses a crazy command, or an S3M uses something not
often used, you will get a message about an unsupported command.

2EH is really the Aural player with just the NONE device, converting the
loaded format into EH.

Not all information is retained in conversion, song titles are converted
into the message block. Empty samples are removed, unused samples are removed,
etc.

The sample packing method is simple but can be effective, and if a sample can
be packed, it will be.
