Not sure just how much info you need and how much you already know.

If you're wanting to know how to assign the DSK strings, then go to the TRACKS window and right click on the next available blank track. From the drop-down menu, select SPECIFIC VSTi/DXi SYNTH FOR MIDI TRACK. This will give you a list of the available instruments. If this is the first time you've used DSK and you don't see it listed, select ADD VSTi PLUGIN and then add the DSK Strings from the folder where you stored it.

This sets up the track ready for the MIDI data to be written or copied.

Hope this isn't just duplicating what you were doing anyway.
