Use the monthly payment plan to get the fully functional version of Artist for $10 a month. Open each wrk and then use the function to create a MIDI file containing all the MIDI data in the wrk file. If you decide to stop making payments before completing the purchase in 12 months, the version will revert to the demo. If the wrk contains a single MIDI clip, dragging the clip from the track view to the desktop or a Windows folder creates a MIDI file from the clip.

Aha.  OK, I'll give that a try.  And who knows, I might actually keep it.  I prefer this interface to Logic Pro's for composing and sequencing.

You may be able to get by with the free SONAR Mac prototype for conversion. I do not have a Mac to test it. If that does not work, Artist is the least cost solution to perform the conversion. There is SONAR Home Studio, less cost than Artist to purchase outright but it does not have a monthly option and has some track count limits.

Thanks all, I'm just going to get the Artist version for now.
 
(BTW, I can't respond to PM's yet, but thanks.)

Glad you got it worked out. 
 
That was a good recommendation Steve. Didn't even think of that. Duh! : )
