Hi Bernie.
Either way will do, from a folder at your PC, USB stick or Floppy.
The new version of EMC also read and convert in "batch mode", you
can i.e. choose a folder as source, and another as target for the
converted files, that way you don't have to convert one by one.
As a start to be familiar to the steps, copy some files into a new
folder, make another one for save work and start explore.
Good luck converting, prepare yourself for some work to make the
styles sound good at the keyboard you convert for.
In fact, I think Technics files are the ones who need most work
after convert.
Cheers
